Mazatlán (Spanish pronunciation: [masaˈtlan] ) is a city in the Mexican state of Sinaloa. The city serves as the municipal seat for the surrounding municipio, known as the Mazatlán Municipality. It is located on the Pacific coast across from the southernmost tip of the Baja California Peninsula.

Mazatlán is a Nahuatl word for "place of deer". The city was colonized in 1531 by the Conquistadors where many indigenous people lived. By the mid-19th century, a large group of immigrants arrived from Germany. Over time, Mazatlán developed into a commercial seaport, importing equipment for the nearby gold and silver mines. It served as the capital of Sinaloa from 1859 to 1873. The German settlers also influenced the local music, banda, with some genres being an alteration of Bavarian folk music. The settlers established the Pacifico Brewery on 14 March 1900. Mazatlán has a rich culture and art community; in addition to the Angela Peralta Theater, the city has many galleries, museums and buildings of historic value.

With a population of 438,434 (city) and 489,987 (municipality) as of the 2010 census, Mazatlán is the second-largest city in the state. It is also a tourist destination, with its beaches lined with resort hotels. A car ferry crosses the Gulf of California, from Mazatlán to La Paz, Baja California Sur. The municipality has a land area of 3,068.48 km (1,184.75 sq mi) and includes smaller outlying communities such as Villa Unión, La Noria, El Quelite, and El Habal. Mazatlán is served by General Rafael Buelna International Airport.

Mazatlán etymologically comes from the Nahuatl language and means "Land of deer" (mazatl "deer" and tlan referring to a place abundant with something).

Originally, the name Presidio of Mazatlán was used for what is now called Villa Unión. The port of Mazatlán served as a reference to arrive to Presidio by sea, and was called the Islands of Mazatlán. By decree of the Estado de Occidente, on September 11, 1828, Presidio of Mazatlán was renamed Villa of the Union. This freed the name Mazatlán (land of deer), and since the port was known as Islas de Mazatlán, the name was adopted.

Indigenous groups were in the region of Mazatlán prior to the arrival of the Spanish. These groups included the Totorames, who lived from the south bank of the River Piaxtla to the Río de las Cañas, as well as the Xiximes, who lived in the mountains in the bordering state of Durango.

According to the Codex Mendoza, the region was conquered under the reign of Tizoc and incorporated into the Aztec Empire.

During the early years of the Spanish conquest in Sinaloa, the region currently occupied by the municipality of Mazatlán remained uninhabited. The nearest town was Chametla, which was occupied by the Spanish in 1531, and lent its name to the province, despite being abandoned shortly afterward.

The city was colonized in 1531 by an army of Spaniards.

In 1534, the Valley of Mazatlán was divided into 25 Castellanos by an unknown person who did not stay there for long. In 1576, Don Hernando de Bazán, Governor and Captain General of Nueva Vizcaya, sent Captain Martín Hernández with his father, brothers, and soldiers to occupy the site of Mazatlán, granting them land and titles in return. The Captain's claims were ratified in the City of Durango in 1639, and endorsed in the same city in 1650.

Nuño de Guzmán's entry to Sinaloa in 1531, and the appointment of the conquered lands as provinces, prompted the internal territorial division of the State. Chametla was occupied by the Spanish, and listed the province extending from the Rio Cañas Elota to the boundary with the province of Culiacán. Both provinces belonged to the kingdom of New Galicia.

In 1565, the town of Chametla was gradually diminished by ongoing Indian raids. That year, Captain Francisco de Ibarra recovered the territory south of the state, rebuilt Chametla, and founded the Villa de San Sebastián (known today as Concordia), and awarded the region to New Vizcaya. The provinces under his jurisdiction included the villages of San Sebastián, Charcas, Copala and Pánuco.

During the last years of the seventeenth century and early eighteenth century, the territory within Sinaloa remained unchanged, until 1732, when the provinces of Sonora and Ostimuri were united, as were the provinces of Sinaloa, Culiacán, and Rosario, with San Felipe and Santiago being the principal cities.

In 1749, Sinaloa was divided into five provinces with their mayors and lieutenancy: Maloya, with jurisdiction over Chametla, Rosario, and San José; Copala, with jurisdiction over San Ignacio, Piaxtla, and Mazatlán; Culiacán, with jurisdiction over Badiraguato, and Sinaloa, which bordered the Mayo River.

In 1786, the intendant system was implemented due to the need to establish a provincial government. Arizpe Municipality was formed out of the territories of Sonora and Sinaloa. That year, the first mayor, Garrido Durán, established eleven subdelegations, eight of them in Sinaloa, with Mazatlán being within the subdelegation of Copala, which was later called San Sebastián.

Among the first decrees that the legislature enacted was that the addition of each of the eleven districts, and this union, corresponding to the Union Villa Mariano Balleza, be given the name of one of the leading insurgents, parish priest Dolores Hidalgo, on the night of September 15, 1810.

In 1813, the Cadiz constitution came into effect. Article 310 of that constitution provided for the installation of local councils in towns that had more than 1,000 inhabitants. In 1814, Fernando VII repealed that constitution but it was later reinstated in 1820, and the first municipalities in Sinaloa were founded.

In the late eighteenth and early nineteenth century, Mazatlán was a native fishing village located north of Cerro de la Aduana. In 1821, it was declared the first port of Mazatlán on Mexico's Pacific coast.

Jurisdictionally, Mazatlán remained dependent on the sub-delegation of San Sebastian, unaffected by the divisions between the states of Sonora and Sinaloa. In 1824, they got together to form the Western State. After the imposition of new internal divisions of five departments and municipalities divided into parties, Mazatlán was in the department of San Sebastian, which was formed with the parties of its name, San Ignacio and the Rosary, and it extended to the River of Reeds.

In 1830, the Western State was divided into two states. The first constitution of the state of Sinaloa, promulgated on December 12, 1831, divided the territory into eleven districts with their respective parties, leaving the district town of La Union separated from Concord and San Ignacio.

Until the early 19th century, Mazatlán was a collection of huts inhabited by indigenous people whose major occupation was fishing, according to Abel Aubert du Petit-Thouars, a French explorer. In 1829, a Filipino banker named Juan Nepomuceno Machado arrived and established commercial relations with vessels coming to Mazatlán from far off places such as Chile, Peru, the United States, Europe, and Asia Pacific. By 1836, the city had a population of between 4,000 and 5,000. It subsequently became the largest port on the Mexican Pacific coast.

In 1846 during the Mexican-American War, Mazatlán was invaded and occupied by the U.S. military as part of the U.S. Pacific Coast campaign. In 1859, the port was blockaded by Captain Sidney Grenfell of the British steamship H.M.S. Amethyst. On November 13, 1864, the French Army and the Imperialist forces took possession of Mazatlán, until they were deported on November 13, 1866, by General Ramón Corona's forces. After customs officials seized twenty-three ounces of gold from the British warship Chanticleer on June 18, 1868, which at the time was blockading the port, its captain, William H. Bridge, threatened to bomb the city on November 22.

During the California Gold Rush, fortune hunters from the United States' East Coast sailed from New York Harbor and other Atlantic ports to Mexican ports in the Gulf of Mexico. After landing, the aspiring miners travelled over land for weeks to Mazatlán, where they would embark from the port to arrive in San Francisco in another four to five weeks.

When Félix Zuloaga Tacubaya proclaimed the Plan of Ignoring the Constitution of 1857, the garrison of the Plaza de Mazatlán did not remain outside this proclamation, and on January 1, 1858, the Plan of Mazatlán was proclaimed, which followed Zuloaga's Plan.

The capital of Sinaloa, until the year 1853, had been Culiacán. However, that year, the capital was transferred to Mazatlán. On July 22, 1867, the federal government passed a law that forbade state capitals from also acting as ports. As a result of this law, on September 20, 1873, the State Legislature decreed that Culiacán would be the state capital again.

The Siglo XIX constitution of 1852 decreed a new internal division in Sinaloa, which reduced it to nine districts by removing San Ignacio, which had been annexed to the Cosalá, and Choix, which had been annexed to El Fuerte. It also amended the name of the district from Villa de la Unión to the port of Mazatlán. That same constitution also decreed the headquarters and council facility policies in each district.

In 1861, the political headquarters were removed and turned into prefectures, and the same year the State Legislature adopted the Act on Municipalities. In 1868, the district had five municipalities in Mazatlán; one in the center and the other four in Villa Unión, Siqueiros, La Noria, and The Milkweed.

On the morning of November 13, 1864, French Navy ships fired twelve cannon shots into the city, causing minor damage to several homes, but not causing any deaths. The attack stopped when the prefect of the city made known to the invaders that the Mexican Army had left the square and the city was formally ceded to the French.

The Mazatlán Times was a weekly published by the American A. D. Jones. The first issue appeared on May 12, 1863. The publisher boasted that his was the only weekly English-language newspaper, not only in Mazatlán and Sinaloa, but throughout Mexico.

In 1873, according to the census of the State, the District of Mazatlán was reduced to three municipalities: Mazatlán, Villa Unión, and La Noria. Siqueiros had been annexed in 1870 to the central municipality, and The Milkweed to La Noria.

Mazatlán's lighthouse (El Faro) began operating in mid-1879. The maritime signals were manufactured in Paris, France, containing a large oil lamp with mirrors, and a Fresnel lens to focus the light. Since the light was static, from a distance it was often mistaken for a star. By 1905, this lamp was converted to a revolving lamp. During that period, the Mazatlán lighthouse was considered to be the naturally highest in the world. Today, the 1000 watt bulb can be seen for 30 nautical miles (60 km). Near the lighthouse shore, famous "divers" (called this even by the Spanish-speaking inhabitants of Mazatlán) perform daring jumps off high rocks into the Pacific Ocean, for tips from onlooking tourists.

On June 26, 1880, Jesus Ramirez, former general in command of 400 men, stormed the garrison of the square and appropriated Mazatlán. The city was subsequently bombed again by the Mexican warship the Democratic, which, during its attack, killed and wounded a high number of women and children. Of the 24 cannon shots fired, only three hit the army headquarters, and the rest landed on neighboring houses.

Angela Peralta (1845–1883), a Mexican opera diva famed throughout the world, died of yellow fever in Mazatlán shortly after her arrival in the port. Legend has it that she sang one last aria from her hotel balcony overlooking the Plazuela Machado. Her memory is held dear by Mazatlecos to this day, and the restored Angela Peralta Theater by the Plazuela keeps her memory alive.

The Cerveceria del Pacífico was founded in the city in 1900 by German immigrants.

In 1912, the municipalities enacted law No.21 as a form of internal division of the State. However, it wasn't until 1915 that the law was abolished by the political directorate, when it erected the first free communes.

With the publication of the decree creating the municipality of Mazatlán in the official newspaper on April 8, 1915, independent life began in the region. The Constitution of 1917, culminating in the first constitutional governor, General Ramón F. Iturbe, born in Mazatlán, confirmed the sixteen municipalities into which the state was divided, which would then be subdivided into receiverships and police precincts.

The City of Mazatlán has the dubious distinction of being the second city in the world after Tripoli, Libya, to suffer aerial bombardment (although the local historical display at the plazuela claims that Mazatlán was the first). During the Mexican Revolution, General Venustiano Carranza (later president), intent on taking the city of Mazatlán, ordered a biplane to drop a crude bomb of nails and dynamite wrapped in leather on the target of Neveria Hill adjacent to the downtown area of Mazatlán. The crude bomb landed off target on the city streets of Mazatlán, killing two citizens and wounding several others.

Mazatlán is also the hometown of Pedro Infante, one of the most popular actors and singers of the Cinema of Mexico's golden years.

Mazatlán was well regarded by film stars such as John Wayne, Gary Cooper, John Huston, and others of their generation as a sportfishing mecca. The hotels along Olas Altas flourished during the 1940s, 1950s and 1960s, supporting this vibrant trade.

In the 1970s, tourism in Old Mazatlán declined as newer venues catering to Western tourists opened on the expanses of beach to the north of the city ("Zona Dorada"). As an example of Mazatlán's tourism expansion, one of the largest timeshare providers in Mexico, Grupo Vidanta, was founded in 1975 with the inauguration of Paraíso Mazatlán (Mazatlán Paradise). This time also saw the expansion of the Hotel Playa Mazatlán, and the construction of many others, a trend that continues to this day.

Next to Infante, Lorena Herrera, one of the most famous actresses and singers in Mexico and Latin America during the final decades of the 20th century and the first decades of the 21st century, is Mazatlán's most famous native. German-born telenovela star Sabine Moussier, a stablemate of Herrera's—both have been under Televisa contract since the 1990s—also grew up in Mazatlán. Hollywood and Broadway actress Sara Ramirez is also a Mazatlán native.

As the 21st century began, the Centro Histórico was rediscovered by newcomers and locals alike, spurring a renaissance of restoration and entrepreneurial endeavors. Once-fine homes that had fallen into literal ruin were restored to their former glory as family homes and boutique businesses. The city has assisted by upgrading infrastructure such as better water, sewer, and electrical services.

Mazatlán experienced two total solar eclipses in relatively rapid succession on July 11, 1991 and April 8, 2024, and it was the first city in North America to experience the latter eclipse.

The town of Mazatlán is organized territorially into nine syndicates:

Mazatlán: Municipal capital, largest and most important tourist destination.

Villa Union: Located 25 km from Mazatlán, second most important town of the municipality. It is said that the first settlers belonged to a Spanish family who arrived there in 1576. Among its economic activities are fishing, agriculture, livestock, fruit growing, aquaculture, and brick making.

El Recodo: So-called for the square shape of the Rio Presidio at this point. It is the cradle of Don Cruz Lizarraga, founder of the international Banda El Recodo. Its economic activities are livestock, agriculture, fruit growing, tanning, and saddlery.

El Quelite: A picturesque and attractive tourist town located 38 km northwest of Mazatlán. The El Quelite River passes through it. Its houses contain the Spanish classical influence predominant in the eighteenth century. Charrería is practiced here, as is the Prehispanic game called Ulama. The main economic activities are: livestock, agriculture, farming and fruit growing.

Mármol de Salcido: This town is 32 km from Mazatlán. It was an important cement and line production center. Its current economic activity is the production of chilies, fodder, and tomatoes; its coast has a large number of pristine beaches.

El Roble: Founded in 1867, it is 32 km from Mazatlán. It became the largest sugar mill in the south of the state. Its main economic activities are agriculture and the production of cheese and honey.

Siqueiros: Originally called Penitas, it then adopted the name of San José de Siqueiros, in honor of the patron saint of the town, and the name of its founder. Founded in 1749, it is located 29 km from Mazatlán on the Presidio River. Among its economic activities are agriculture, livestock, and vegetables.

La Noria: Located 35 km northwest of Mazatlán, its first settlers date from the late sixteenth century. Among its economic activities are livestock, agriculture, and saddlery. It is close to Presa Picachos. A few miles away is the famous Vinata de Los Osuna, a major producer of blue agave, belonging to the family of the same name.

El Habal: A village located 10 km north of Mazatlán. Its inhabitants are engaged in animal husbandry, farming, and fruit growing.

The town of Mazatlán is located in the southern Sinaloa. With a land area of 3,068.5 square kilometres (1,184.8 sq mi) (5.3% of the total area of the state), it is Sinaloa's ninth largest municipality. It is bordered on the north by the municipality of San Ignacio and the state of Durango, on the south by the town of El Rosario and the Pacific Ocean, on the east by the town of Concordia, and on the west by the Pacific Ocean.

Its average elevation is 10 metres (33 ft) above sea level.

The orography is determined by the ramifications of the Sierra Madre Occidental on the northwestern coastal plain bearing towards the Pacific Ocean, where the hills rise towards Vigia, Punta de Materén, and the Monte chair. This orography, before entering the municipality of San Ignacio, takes the name of Sierra del Metate, whose characteristic is the formation of Peak Metate.

At the edge of Mazatlán and Concordia runs the Sierra del Metate and Panuco. In this county, the Sierra Madre Occidental is diverted to penetrate Durango, leaving before some detachments, such as the Sierra de San Juan and the Friars, and constitutes, in of its topography, the following hilly areas:

To the north end of town one can see the Friars extending northwest, with elevations ranging from 150 to 1,900 meters above sea level. In the northwestern portion, El Quelite branches have elevations of 50–700 meters above sea level. On the south-east and north sides, Arroyo de La Noria and some tributaries of the River El Quelite rise. The town of La Noria is located in this same part of the mountain, extending in a northwesterly direction at 300 and 500 meters above sea level. On its western side, the Zapote Brook begins. The Sierra de San Marcos is located in the north at 50 to 700 meters above sea level. Forming the southeastern and northwestern slopes are Brook Copala and some tributaries of the Presidio River.

The geological nature of the municipality, primarily made of sedimentary rock, gives rise to the outcrop of fragments of marine and consolidated rocks, and volcanic and metamorphic rocks. Mazatlán generally consists of tonalite and monsonitas belonging to the Middle Tertiary: rhyodacites, rhyolites and ignimbrites with tuffaceous sediments at the base outcrops; andesitic rocks and felsitic late Early Cretaceous conglomerate, sandstone, tuff, sandy tuff "tobalítica", conglomeratic sandstone, arkose storm origins and late Tertiary rhyolitic tuffs, limestones, shales, sandstones and quartzites of coal, gravel and conglomerates that make alluvial fans and slope deposits; rhyolite and rhyodacite tuffs of the same composition, dacite and Lower Tertiary andecita medium; volcanic and pyroclastic spills of andecitic Cretaceous composition; plutonic rocks of basic composition and basic ultra late Paleozoic, Cretaceous limestones, conglomerates of igneous and metamorphic songs; sediments within the course of rivers and streams and sandy sediments, gravel, silt, and orange.

El Quelite River, and the Zapote, La Noria, and Los Cocos streams form part of the water resources of the municipality in the southwestern and southeastern slopes; these streams increase its volume considerably during the rainy season.

The current of the El Quelite River recorded a catchment of 835 square kilometers, where it drained annually for an average of 107 million cubic meters with variations ranging from 78 to 163 million cubic meters. This hydrological current passing through the town of Mazatlán touches the towns of El Castillo, Las Juntas, Amapa, Los Naranjos, Milkweed, Modesto Station, and El Recreo. After traveling a distance of 100 kilometers from its source, it discharges into the Pacific Ocean. The El Zapote and Los Cocos streams drain in a southeasterly direction to end at the Presidio River, up to the villages from which they take their names.

On the southeast slope of the Sierra del Quelite is the De La Noria stream, and on the north side of it are some tributaries from the El Quelite River. The La Noria stream drains in a southeasterly direction of the town of the same name, and finally ends in the Presidio River.

El Zapote stream is formed on the western slope of the Sierra de La Noria, and moves in a southwesterly direction. In passing, it touches the towns of Zapote and El Recreo, and empties into the Pacific Ocean.

On the northern slopes of the Sierra del Salto, near the village of the same name in the state of Durango, the Presidio River moves southeastward and makes a journey of 167 kilometers. Its catchment area is 5,614 square kilometers, with an average annual expenditure of 900 million cubic meters, a maximum of 2,225 and a minimum of 550 million cubic meters. Populations on its banks are Los Cocos, El Zapote, El Placer, El Tecomate, Copala, El Recodo, Porras, Villa Unión, Alley Ostial, and Alley Rosa.

The coasts of the municipality extend over 80 kilometres (50 mi), and sandy beach sediments are formed in the northwestern flank of the head of the municipality. There is a substance classified as berms, which is a soft sediment formation. The coast consists of gravel and conglomerates that form alluvial fans and slope deposits.

In the southwestern corner, Huizache Lagoon occupies an area of 4,000 hectares (40.0 square miles). It receives the maritime influence through the Ostial estuary and freshwater diversion channel, and receives water from the Presidio River.

The coastline of the municipality is lined with shrimp and small-scale flake fishing vessels.

Cooperatives are distributed in the estuaries of the Escopama, Salinitas, El Veintinueve, and Estero Uriah Huizache lagoon.

Most of the islands of the municipality are formed by ignimbrites, rhyolitic tuffs and tuffaceous sandstones of altered and deformed light color.

Bird Island is located between the extreme equatorial coordinates of 106 ° 28'34 " west longitude and 23 ° 15'25" north latitude; its area is about 0.4 square kilometers, 1.1 kilometers long, and maximum and minimum range of 800–650 meters respectively.

Deer Island is located between 106 ° 27'60 " west longitude and 23 ° 14'03" north latitude; its approximate length is 1.850 meters (6 ft 0.8 in), and its width varies between 250 and 700 meters (820 and 2,300 ft).

Crestón Island is located on the western edge of the outer bay of Mazatlán, and it has a length of 700 meters and a maximum width of 800 meters. To the northwest, about 3 miles away, small islands like "Southern Brother" and "Northern Brother" (the first with 46.3 meters in elevation) and Turtle Rock rise 1.5 meters above sea level at its highest ridge.

Goats Island is similar to Crestón's appearance; it has a height above sea level of a little over 50 meters.

Stone Island is the most important part of the municipal coastline; its size is the largest of all because it has 30 square kilometers, and is approximately 14.5 miles long by 2.5 wide. Despite its name, Stone Island is a peninsula that connects to the continent near the Mazatlán International Airport.

Located just south of the Tropic of Cancer, Mazatlán has a tropical savanna climate (Aw), bordering a hot semi-arid climate (BSh), with a marked and rather long dry season and an average annual temperature of 25 °C.

During the summer months, with the humidity factor, temperatures usually feel well above what the thermometer shows.

During the period of 1940–1980, the municipality experienced an average annual 748 mm of precipitation, with a maximum of 215.4 mm in 24 hours, and 90.4 mm was observed in one hour. During the same period the average evaporation rate per year was 2146.80 mm; the prevailing winds are in a northwesterly direction at an average speed of 5.0 meters.

The flora of Mazatlán are tabachines, eucalyptus, laurels, and poplars. Its fauna includes birds like ducks, herons, and pelicans. There are armadillos, raccoons, and a variety of marine species such as whales, dolphins, turtles, and fish. White-tailed deer is one of the main animals that characterizes Mazatlán. Today, there are fewer animals and plants than before, due to the way humans have changed the ecosystem.

Mazatlán has several protected areas, one of which is the Protection of Flora and Fauna Area (APFF). CACAXTLA Plateau is located between the towns of Mazatlán and San Ignacio in the central part of the state of Sinaloa, and contains a portion of the coastal habitats of the state, and is the largest in Sinaloa. This wealth of habitats favors the presence of 66 species of flora and fauna listed in NOM-059-ECOL-2001 and CITES and 47.5% of endemism reported for Sinaloa, plus charismatic and commercially important species. At the same time, the protected area is home to a population of 7,964 inhabitants, whose livelihood depends entirely on the extraction of natural resources in this area. The relationship between nature and society in the APFF Cacaxtla Plateau is the focus of this program.

Tourism and fishing are the main industries in Mazatlán. The city houses the main beach resorts, and has the second largest fishing fleet in Mexico. The most processed seafood products in the city are shrimp and tuna. The first Mazatlán hotel with a restaurant inside was named Canton La Fonda, and became operational in 1850. It was owned by a Chinese immigrant, Luen-Sing, which called the establishment the Luen-Sing Hotel. In 1864, there were three hotels and three restaurants in Mazatlán, with more opening in the late nineteenth century. Today, more than twenty miles of beaches are the main attraction, and the city contains a large number of hotels, restaurants, bars, and shops. The city is also home to the Pacífico brewery, a coffee factory, and two power plants.

• Isla de la Piedra Beach: A miles-long Located in the southern part of the city on the peninsula that is separated from the old city by the entrance to the main commercial harbor; only accessible by car on a recently paved road from just off the airport access road, or, by small passenger ferries that provide regular service from the docks at the edge of the historic center.

The Historic Center of Mazatlán, among whose former inhabitants are French, German, Chinese, Italian, Spanish and Americans (many contemporary inhabitants of Mazatlán are descended from these), was named Heritage of the Nation on 12 March 2001. A civil association composed of a group of Mazatlán locals have managed to revive this area, along with the support of various organizations, companies, and government authorities. Among the buildings and areas of high cultural value are the Cathedral, Plazuela República, Plazuela Zaragoza, Plazuela Machado, Plazuela Hidalgo, the Angela Peralta Theater, the old Hotel Iturbide (today the Municipal Arts Centre), Mansion of Redo, Melchers House, House of Retes, Corvera Building, Bank of London and Mexico Building, Haas House, Temple of San José, and various others.

Mazatlán hosts several events annually, the most important being the International Carnival of Mazatlán, which was 114 years old in 2012. Other important events are the Mazatlán Cultural Festival and the José Limón International Dance Festival, celebrated every year in the winter and spring, respectively. There is also the Book Fair and Arts of Mazatlán (Feliart) and Mazatlán Book Fair (FELIMAZ).

Another important event is the International Motorcycle Week, which attracts thousands of motorcyclists from around the country as well as from abroad, and is held each year during Easter week.

In sports, Mazatlán is home to the Pacific International Triathlon held in April, and the Pacific International Marathon, which is held every year in late November and early December, and is attended by athletes from around the world.

In 2012, Mazatlán was chosen as the host city for the tenth installment of Premios Oye!, prizes awarded by the National Academy of Music in Mexico, and the Volleyball Olympic qualifiers for the Olympic Games in London 2012.
