Bayamón (Spanish pronunciation: [baʝaˈmon], locally [baʝaˈmoŋ]) is a city and municipality in Puerto Rico. Located on the northeastern coastal plain, it is bounded by Guaynabo to the east, Toa Alta and Naranjito to the west, Toa Baja and Cataño to the north, and Aguas Buenas and Comerío to the south. Part of the San Juan metropolitan area, Bayamón is spread over 11 barrios and the downtown area and administrative center of Bayamón Pueblo. With a population of 185,187 as of the 2020 census, it is the second most populated municipality in the archipelago and island after the capital of San Juan.

Two theories exist about the origin of the name Bayamón. According to one, it was named after the local cacique, Bahamon. The other theory states the name was derived from the Taino word Bayamongo, which is the native name of the river that runs across this region, implying that Bayamón is the area around this main river, which later on became the center of the city's development.

Bayamón is nicknamed "City of the Chicharrón" or "Pork Rind City" (Ciudad del Chicharrón) after the popular fried dish, locally known as chicharrón volao, that is often sold as street food. Other nicknames include "City of Cowboys" (Ciudad de Vaqueros), after the local sports team, "City of the Sciences" (Ciudad de las Ciencias) after the popular tourist educational attraction, and, more recently, Ciudad del Tapón, due to the high amounts of road traffic congestion there.

The Taino, the indigenous peoples who encountered European explorers and settlers, were the long-time settlers in this area. Before the foundation of the municipality, Hacienda Santa Cruz was established near the Bayamón River in 1750. The Spanish colonist Juan Ramírez de Arellano formally established Bayamón as a Spanish settlement on May 22, 1772, on a hill known as Alto del Embarcadero. The establishment of its current parish church on that same spot also dates to this year.

In 1821, Marcos Xiorro, an African slave, planned to lead a revolt against the sugarcane plantation owners and the Spanish colonial government in Puerto Rico. The slave conspiracy was revealed and suppressed, but Xiorro became a hero among the slaves. He is part of Puerto Rico's folklore. Marco Xiorro was owned by Vicente Andino, a militia captain who owned a sugarcane plantation in Bayamón. An earthquake in 1867 caused damages in Bayamón, particularly to its parish church.

Puerto Rico was ceded by Spain in the aftermath of the Spanish–American War under the terms of the Treaty of Paris of 1898 and became a territory of the United States. In 1899, the United States Department of War conducted a census of Puerto Rico finding that the population of Bayamón was 19,940. The city grew considerably during the start of the 20th century. The area became home to numerous factories specializing in textiles, fertilizer, aluminum between 1901 and 1920. During this time the city also became home to financial institutions such as the Puerto Rico Commercial Bank (Banco Comercial de Puerto Rico), the American Colonial Bank, the First National City Bank of New York, the Chase Manhattan Bank and the Banco Popular de Puerto Rico. This developed and strengthened Bayamón's economy and turned it into both an industrial and commercial hub. The city's infrastructure also developed with the establishment of a bigger sewer system.

The city was also host to some of the events of the VIII Pan American Games in 1979.

Hurricane Maria struck Puerto Rico on September 20, 2017, causing large-scale damage and destruction to infrastructure. Numerous landslides occurred in Bayamón as a result of the hurricane's significant amount of rainfall. In Bayamón, around 300 homes were destroyed, and two people were killed by Hurricane María. Many municipal buildings, and the Goya Foods factory in Bayamón sustained significant damage.

Bayamón lies on the northern coastal plain region and Northern Karst Belt in northeastern Puerto Rico. It is bordered by the municipalities of Toa Baja, Cataño, Comerío, Aguas Buenas, Toa Alta, Naranjito, and Guaynabo. Bayamón has a surface area of 43.5 square miles (113.1 km2). The terrain is mostly flat, but it does include some large hills such as La Peña and Vergaras.

Bayamón is Puerto Rico's second-most populous municipality and is part of the large metropolitan area centered around San Juan. Other cities included in the metropolitan area are Guaynabo, Cataño, Toa Baja, Canóvanas, Carolina and Trujillo Alto. Bayamón is served by the Luis Muñoz Marín International Airport. Despite the city's size, it has no weather station.

The rivers that pass through Bayamón include the Río Bayamón, Río Hondo, Río Minillas, Río Bucarabones and Río Cuesta Arriba.

Like all municipalities of Puerto Rico, Bayamón is subdivided into barrios. The municipal buildings, central square and large Catholic church are located in a small barrio referred to as "el pueblo".

Barrios (which are, in contemporary times, roughly comparable to minor civil divisions) and subbarrios, are further subdivided into smaller areas called sectores (sectors in English). The types of sectores may vary, from normally sector to urbanización to reparto to barriada to residencial, among others.

Comunidades Especiales de Puerto Rico (Special Communities of Puerto Rico) are marginalized communities whose citizens are experiencing a certain amount of social exclusion. A map shows these communities occur in nearly every municipality of the commonwealth. Of the 742 places that were on the list in 2014, the following barrios, communities, sectors, or neighborhoods were in Bayamón: Abra Estrecha, Barriada Vista Alegre, Juan Sánchez, Nuevo, Bda. Cedeño in Pájaros, Collores in Santa Olaya, Corea, Dajaos, El Chícharo, Sector Gandul, El Volcán, La Cambija, La Caridad, La Morenita, Los Viejitos, Papito, Sergio Reyes, Parcelas Sabanas, and Punta Brava.

Bayamón is the site of several notable Puerto Rican landmarks and places of interest. Bayamón Central Park is a public park where people gather and relax. Bayamon also hosts the Braulio Castillo Theater, the Francisco Oller Museum, and the José Celso Barbosa Monument. The Bayamón City Hall building is notable by being built across a major divided highway. While walking through a connecting corridor, right above the road, pedestrians can see passing cars underneath. It is believed to be the only building of its class in the world.

One of the most popular attractions in Bayamón is the Parque de las Ciencias. It is a science-themed park with various exhibitions and attractions. It is located in the middle of karstic hills. An observation building on one of the hills provides a good view of the metropolitan area. The building hosts antennas for government and civil communication.

El parque del tren was a park featuring what was then Puerto Rico's only working train. It featured a DC-3, which had been used by United Airlines. In 2001, the park was dismantled and destroyed in the course of major road construction. What is left of the park is a small plaza for activities and an area for jogging and passive entertainment. The area is now known as "Parque del Nino" or "Children's Park".

Shopping is a major tourist activity in Bayamón. Plaza del Sol and Plaza Rio Hondo are large commercial centers in the city.

A suspension bridge in Bayamón is a pedestrian-only bridge, at the time it was built, it was believed to be one of only three of its kind in Puerto Rico.

To stimulate local tourism during the COVID-19 pandemic in Puerto Rico, the Puerto Rico Tourism Company launched the Voy Turistiendo (I'm Touring) campaign in 2021. The campaign featured a passport book with a page for each municipality. The Voy Turisteando Bayamón passport page lists Centro de Conservación de Manatíes, Paseo Lineal over the Bayamón River, and Ron Del Barrilito in the Hacienda Santa Ana, as places of interest.

All municipalities in Puerto Rico are administered by a mayor, elected every four years. The current mayor of Bayamón is Ramón Luis Rivera Jr., of the New Progressive Party (PNP).

The current flag of Bayamón features the Nordic cross found in many Northern European flags and is colored in blue and yellow over a white field. It was embroidered by Gloria M. León and maintains the design and colors of its coat of arms.

This shield is a symbol and synthesis of the history and the values which distinguish the city of Bayamón. The main colors of the shield are blue and silver, representing the waters of the Bayamón River and recalling that it was on these banks that the first hydraulic sugarcane refinery of Puerto Rico was established in 1549. The center contains the Holy Cross (Santa Cruz), patron of the first church of the municipality and the name of the old sugarcane refinery "Santa Cruz", which was the historical origin of the town of Bayamón. The sugarcane flowers (guajana) allude directly to the sugarcane industry that is of social and economic importance to the origin and development of Bayamón.

The five-tower crown, which is used for cities, was assigned to Bayamón as an exception for its extraordinary urban development, the magnitude of its population and for its religious dignity, which will possibly be raised to become Episcopal seat. The motto "IN HOC SIGNO VINCES" makes reference to Emperor Constantine when in the 4th century had the vision in which the victory was promised to him if it accepted the cross of Christianity as his banner.
