Batanes, officially the Province of Batanes (Ivatan: Provinsiya nu Batanes; Ilocano: Probinsia ti Batanes; Filipino: Lalawigan ng Batanes, IPA: [bɐˈtanes]), is an archipelagic province in the Philippines, administratively part of the Cagayan Valley region. It is the northernmost province in the Philippines, and the smallest, both in population and land area. The capital is Basco, located on the island of Batan and also the most populous in the province.

The island group is located approximately 162 kilometers (101 mi) north of the Luzon mainland and about 190 kilometers (120 mi) south of Taiwan (Pingtung County), separated from the Babuyan Islands of Cagayan Province by the Balintang Channel, and from Taiwan by the Bashi Channel.

The name Batanes is a hispanicised plural form derived from the Ivatan endonym Batan.

The ancestors of today's Ivatans descended from Austronesians who migrated to the islands 4,000 years ago during the Neolithic period. They lived in fortified mountain areas called idjangs and drank sugar-cane wine, or palek. They used gold as currency and were farmers. They were seafarers and boat-builders. Batanes was a major site for the Maritime Jade Road, one of the most extensive sea-based trade networks of a single geological material in the prehistoric world, operating for 3,000 years from 2000 BCE to 1000 CE.

In 1687, the British explorer, privateer, and naturalist William Dampier visited the islands and named them in honour of prominent Dutch and British figures. Itbayat was named "Orange Isle" after William of Orange. Batan was named "Grafton Isle" after Henry FitzRoy, 1st Duke of Grafton. Sabtang Isle was named "Monmouth Isle" after James Scott, 1st Duke of Monmouth. During his stay in August and September 1687, Dampier made valuable observations about settlement types and subsistence of the inhabitants of the Batanes. He mentioned the existence of terraced and defended settlements on elevated terrain (now known as ijang), and listed various types of types of tubers and vegetables, and pigs and goats as common food sources, but notably no wet rice or cattle.

In 1783, the Spanish claimed Batanes as part of the Philippines under the rule of Governor-General José Basco y Vargas. Batanes was ruled as part of the Provincia de Cagayan. The Bashi Channel was increasingly used by English East India Company ships and the Spanish authorities brought the islands under their direct administration to prevent them falling under British control. The Ivatan remained on their idjang castle-fortresses for some time. In 1790, Governor Guerrero decreed that Ivatans were to live in the lowlands and leave their remote idjang. The mangpus, or indigenous Ivatan leaders, headed by the Ivatan hero Aman Dangat, revolted against the Spanish invaders.

Using guns, the Spanish ended the revolution, killing Aman Dangat and several other Ivatan leaders. Basco and Ivana were the first towns established under full Spanish control. Mahatao was then administered by Basco, while Uyugan and Sabtang, by Ivana. Itbayat was not organized until the 1850s, its coast being a ridge. Soon, Ilocanos came to the islands and integrated with the local population.

Roads, ports, bridges, churches and government buildings were built in this time. Limestone technology used by the Spanish spread to the islands, making bridges strong and fortified. Some of these bridges still remain at Ivana and Mahatao. By 1890, many Ivatans were in Manila, and became ilustrados, who then brought home with them the revolutionary ideas of the Katipunan. These Ivatans, who were then discontented with Spanish rule, killed the ruling General Fortea and declared the end of Spanish rule.

Toward the end of the Spanish administration, Batanes was made a part of Cagayan. Due to historical reasons from that time, some segments of Taiwan society argue that the islands should not belong to the Philippines. Batanes was created as a sub-province of Cagayan on August 20, 1907 by the approval of Act No. 1693. In 1909, the new American authorities organized it into an independent province, upon the approval of Act No. 1952. During the American colonial period, additional public schools were constructed and more Ivatan became aware of their place in the Philippines.

In 1920, the first wireless telegraph was installed, followed by an airfield in 1930. New roads were constructed and the Batanes High School was instituted.

Because of their strategic location, the islands were one of the first points occupied by the invading Japanese imperial forces at the outbreak of the Pacific War. On the morning of December 8, 1941, the Batan Task Force from Taiwan landed on the Batan Islands, which became the first American territory occupied by the Japanese. The purpose of the invasion, to secure the small airfield outside Basco, was accomplished without resistance. Japanese fighters from Basco took part in the raid on Clark Air Base the following day. Over the next several days, the success of the Japanese bombing of Clark Field rendered a base at Basco unnecessary, and on December 10, 1941, the naval combat force was withdrawn to participate in the invasion of Camiguin.

As part of an administrative reorganization, the province of Batanes was downgraded to a municipality of Cagayan from 1942 to 1944. Upon its restoration, Victor de Padua, an Ilocano who was one of the first School Superintendents on Batan, was made Provincial Governor. Early in 1945, the island was liberated by the Philippine Commonwealth forces of the 1st and 12th Infantry Division of the Philippine Commonwealth Army.

Batanes was briefly marred by political violence during the 1969 presidential elections, when the Philippine Constabulary's Special Forces allowed motorcycle-riding goons dubbed the "Suzuki boys" to secure the victory of Rufino Antonio Jr., an ally of President Ferdinand Marcos, as representative of the Lone District of Batanes in the House of Representatives of the Philippines through a campaign of terror and intimidation. The resulting outcry led to the Supreme Court decrying the "rape of democracy" in the province, and annulled Antonio's victory in 1970 in favor of his rival, Jorge Abad.

In 1984, Pacita Abad, the foremost Ivatan visual artist, became the first woman to be awarded the Ten Outstanding Young Men (TOYM) award, breaking 25 years of male dominance. In her acceptance speech, she said, "it was long overdue that Filipina women were recognized, as the Philippines was full of outstanding women" and referred proudly to her mother.

In 1993, the Batanes Protected Landscape and Seascape, which encompassed the entire province, was listed in the Tentative List of the Philippines for UNESCO World Heritage Site inscription in the future.

In 1997, the Indigenous Peoples Rights Act (IPRA) was passed in Philippine Congress. The law paved the way for the indigenous territorial rights of the Ivatans. The province has since promoted its Ivatan roots. Part of the Ilocano population has returned to mainland Luzon. On December 7, 2004, Pacita Abad died after finishing her last international artwork while suffering from cancer.

A minor dispute between the Philippines and Taiwan erupted in 2007, after Taiwan Times published an editorial written by Tamkang University professor Chen Hurng-yu, claiming that Taiwan has territorial claims over Batanes and encouraging the Taiwanese government to take over the province. This, despite the islands being first claimed by Spanish Philippines in 1783 and later incorporated and administered by the Philippines without any contesting nation in the 18th century.

The province has a total area of 219.01 square kilometers (84.56 sq mi) comprising ten islands situated within the Luzon Strait between the Balintang Channel and Taiwan. The islands are sparsely populated and subject to frequent typhoons. The three largest islands, Batan, Itbayat, and Sabtang, are the only inhabited islands.

The northernmost island in the province, also the northernmost land in the entire Philippines, is Mavulis (or Y'ami) Island. Other islands in the chain are Misanga (or North), Ditarem, Siayan, Diogo (or Dinem), Ivuhos, and Dequey. The islands are part of the Luzon Volcanic Arc.

Almost one-half of Batanes is hills and mountains. Batan Island is generally mountainous on the north and southeast. It has a basin in the interior. Itbayat Island slopes gradually to the west, being mountainous and hilly along its northern, eastern coast. On Sabtang, mountains cover the central part, making the island slope outward to the coast.

The islands are situated between the vast expanse of the waters of Bashi Channel and Balintang Channel, where the Pacific Ocean merges with the China Sea. The area is a sea lane between the Philippines and Japan, China, Hong Kong and Taiwan. It is rich with marine resources, including the rarest sea corals in the world.

The province is hilly and mountainous, with only 1,631.5 hectares (4,032 acres) or 7.1% of its area level to undulating terrain. 78.2% or 17,994.4 hectares vary from rolling hills to steep and very steep. Forty-two percent (42%) or 9,734.40 hectares (24,054.2 acres) are steep to very steep land. Because of the terrain of the province, drainage is good and prolonged flooding is non-existent.

The main island of Batan has the largest share of level and nearly level lands, followed by Itbayat and Sabtang, respectively. Itbayat has gently rolling hills and nearly level areas on semi-plateaus surrounded by continuous massive cliffs rising from 20 to 70 meters (66 to 230 feet) above sea level, with no shorelines. Sabtang has its small flat areas spread sporadically on its coasts, while its interior is dominated by steep mountains and deep canyons. Batan Island and Sabtang have intermittent stretches of sandy beaches and rocky shorelines.

The terrain of the province, while picturesque at almost every turn, has limited the potential for expansion of agriculture in an already very small province.

Batanes has a tropical climate (Köppen climate classification Am). The average yearly temperature is 26.0 °C (78.8 °F). The average monthly temperature ranges from 22.0 °C (71.6 °F) in January to 28.5 °C (83.3 °F) in July, similar to that of Southern Taiwan. Precipitation is abundant throughout the year. The rainiest month is August. The driest month is April. November to February are the coldest months.

There is a misconception that Batanes is constantly battered by typhoons. Batanes is mentioned frequently in connection with typhoons, because it holds the northernmost weather station in the Philippines, thus, it is a reference point for all typhoons that enter the Philippine area. In September 2016, Typhoon Meranti impacted the entire province, including a landfall on Itbayat.

Batanes is subdivided into 6 municipalities, all encompassed by a lone congressional district.

The 6 municipalities of the province comprise a total of 29 barangays. Ihuvok II in Basco was the most populous in 2010, and Nakanmuan in Sabtang was the least.

The population of Batanes in the 2020 census was 18,831 people,. The population density was 86 inhabitants per square kilometer or 220 inhabitants per square mile.

The natives are called Ivatans. They share prehistoric cultural and linguistic commonalities with the Babuyan on Babuyan Island and the Tao people of Orchid Island.

This divided homeland is a result of the Dutch invasion of Taiwan in 1624 (Dutch Formosa) and Spanish invasion in 1626 (Spanish Formosa). The northern half of the Ivatan homeland, Formosa and Orchid Island were part of the Viceroyalty of New Spain. This area came under Dutch governance. The Dutch were expelled in 1662 by forces of the Chinese Southern Ming dynasty, led by the Chinese pirate Koxinga who then set himself up as the King of Taiwan.

The southern half of the Ivatan homeland, the islands of Batanes, was reinforced and fortified by Spanish refugees from Formosa, before being formally joined in the 18th century with the Spanish government in Manila.

An Ilocano minority population lives in Batanes. Some have left and returned to mainland Luzon.

The main languages spoken in Batanes are Ivatan, which is spoken on the islands of Batan and Sabtang. Itbayaten is spoken primarily on the island of Itbayat. The Ivatan which is dominant in the province is considered to be one of the Austronesian languages. From college level down to elementary level, the language is widely spoken. The Ivatans widely speak and understand the Ilocano (lingua franca of northern Luzon), Filipino, and English languages.

Ivatan-speaking communities can be found in other parts of the country, mainly in mainland Luzon, as well as overseas.

An extensive survey of the ecology of Batanes provided the scientific basis for confirming the need for a national park in Batanes protecting the Batanes protected landscapes and seascapes, proposed as a UNESCO World Heritage Site, submitted in August 1993. An effort is underway to declare the whole province, along with the sugar central sites in Negros, as a UNESCO World Heritage Site.

The province is the home of the unique conifer species Podocarpus costalis. Although it is reportedly growing in some other places such as coasts of Luzon, Catanduanes and even Taiwan, full blossoming and fruiting are observed only in Batanes. Its fruiting capacity on the island remains a mystery but is likely due to several factors such as climate, soil and type of substratum of the island.

Several species of birds, bats, reptiles and amphibians inhabit the island. Many of those are endemic to the Philippines. The island is a sanctuary for different migratory birds during winter in the Northern Hemisphere. The Batanes archipelago, along with the nearby Babuyan Islands, have been designated an Important Bird Area (IBA) by BirdLife International because they support significant populations of resident Taiwan green pigeons, Ryukyu scops-owls and short-crested monarchs, Chinese egrets on passage, and wintering yellow buntings.

About 75% of the Ivatans are farmers and fishermen. The rest are employed in the government and services sector. Garlic and cattle are major cash crops. Ivatans plant camote (sweet potato), cassava, gabi or tuber and a unique variety of white uvi. Sugarcane is raised to produce palek, a kind of native wine, and vinegar.

In recent years, fish catch has declined due to the absence of technical know-how. Employment opportunities are scarce. Most of the educated Ivatans have migrated to urban centers or have gone abroad.

A wind diesel generating plant was commissioned in 2004.

Distance and bad weather work against its economic growth. Certain commodities like rice, soft drinks, and gasoline carry a 75% to 100% mark-up over Manila retail prices.

The island province of Batanes is accessible by air, via Basco Airport and Itbayat Airport. There are daily flights from Manila by Philippine Airlines bound to Basco Airport at Batan Island. There are also flights from Tuguegarao City (Cagayan) by Sky Pasada as of 2024. These two airlines make Batan Island accessible from the mainland via air travel. The other local airlines previously serving Basco Airport have stopped their transport services after the COVID 19 Pandemic. As of 2024, PAL Express has flown to Batanes since May 2013. Meanwhile, Itbayat, an island Municipality of the Province of Batanes, is accessible via Basco Airport. There are no direct flights from the mainland to Itbayat. Itbayat may also be accessed via ferry boats from Basco. Meanwhile, Sabtang, also an island municipality like Itbayat, is accessible via ferry boats from Batan Island, particularly from Ivana Port, a Municipality in the main Island of Batan.

The Ivatan people of Batanes are one of the most egalitarian societies in the Philippines. The prime motivator of the cultural values of the Ivatans are imbibed in their pre-colonial belief systems of respecting nature and all people. The Ivatans, both the older and younger generations, have one of the highest incidences of social acceptance to minority groups in the country.

The Ivatans have a high respect for the elderly and the prowess of natural phenomena such as waves, sea breeze, lightning, thunders, earthquakes, and wildlife congregations. Discriminating someone based on skin color, ethnic origin, sexual orientation, gender identity, age, and traditions on nature is unacceptable in Ivatan values. Land grabbing is a grave crime in Ivatan societies, making ancestral domain certification an important part of Ivatan jurisprudence since the enactment of the IPRA Law.

The entire province is listed in the UNESCO tentative list for inscription in the World Heritage List. The government has been finalizing the site's inscription, establishing museums and conservation programs since 2001. Seven intangible heritage elements of the Ivatan have been set by the Philippine government in its initial inventory in 2012. The elements are undergoing a process to be included in the UNESCO Intangible Cultural Heritage Lists.

• Sabtang Island is undisturbed and unspoiled. It has intermittent white sand beaches with steep mountains and deep canyons with small level areas sporadically found along the coastline. Southwest of Batan Island, Sabtang is accessible by 30-minute falowa ride from Radiwan Port in Ivana. Sabtang Island is also the take-off point for Ivuhos Island from Barangay Nakanmuan.
• Itbayat Island is located north of Batan Island. Itbayat is shaped like a giant bowl. The island is surrounded by massive boulders and cliffs rising from 20 to 70 feet (6.1–21.3 metres) above sea level and has no shoreline. It has a dirt airstrip for light aircraft. A regular ferry runs the Batan-Itbayat route. Travel time is about four hours by falowa from Basco Seaport. A light plane flies from Basco Airport to Itbayat at around P1,875 per person and leaves only when the plane is full.
• Batan Island is the most populated island of the province. It is composed of four municipalities: Basco, Ivana, Uyugan, and Mahatao. Basco is the center of commerce and the seat of the provincial government.
• Mount Iraya is a dormant volcano standing at 1,517 meters (4,977 feet) whose last eruption was recorded in 505 AD. Mountaineering, trekking, and trailblazing are recommended sports activities on the mountain. Walking distance from Basco, the top of Mt. Iraya can be reached in about three hours.
• Mavulis Island is the northernmost island of Batanes. From this location, one can see Formosa (Taiwan) on a clear day. Tatus or coconut crabs abound on the island surrounded by rich marine life.
• Di-atay Beach is a cove with multi-colored rocks and white sand ideal for picnics and beachcombing. Located along the highway of Mahatao, it is 9.85 kilometers (6.12 miles) from Basco.
• Songsong in Chadpidan Bay is an hour of exhilarating trek from Basco proper (3 kilometers (1.9 miles)). It is famous for its beautiful sunset view.
• Naidi Hills is walking distance from Basco.
• Chawa Cave is for the more adventurous. An enchanted cave with a natural salt bed whose mouth opens to the south China Sea and is accessible through the boulders of Chawa Point in Mahatao. It is 4 kilometers (2.5 miles) from Basco.
• Sitio Diura at Racuj-a-Ide is the fishermen's village at Mananoy Bay. Fishing season is marked by a festival in mid-March called Kapayvanuvanua. Visitors are treated with fresh fish delicacies from the Pacific Ocean. Within the area is the legendary Spring of Youth and living cave with crystal limestone formations. The bay is nine kilometres (5.6 miles) from Basco.
• Nakabuang Cave is 5.5 kilometers (3.4 miles) from San Vicente Centro in Sabtang.
• Mt. Matarem is an extinct volcano 495 meters (1,624 feet) at its summit. It is eight kilometers (5.0 miles) from Basco.
• White Beach at Vatang, Hapnit, and Mavatuy Point, all in Mahatao.
• Storm-proof Stone houses in Batanes many residents during typhoon made up their already-fortified houses with wood and secured the roofs with nets and ropes. This was done to ensure that the structures—which symbolize the Ivatan's strength and resilience against disasters—outlast the high-pressure winds of a typhoon that is expected to unleash. Tapangkos or covering were also installed on the doors and windows of several buildings in Batanes, including the capitol building. During heavy storms, it was also a time for Bayanihan of the residents as they helped each other tie-down roofs.

• Radar Tukon was a United States weather station on a hilltop. It offers a magnificent 360-degree view of Batan Island, the South China Sea, Mt. Iraya, Basco proper, boulder lined cliffs and the Pacific Ocean. At present, it houses the northernmost weather station in the Philippines, the Basco Radar Station, and is only 2.75 kilometers (1.71 miles) from Basco.
• Old Loran Station housed a US Coast Guard detachment for almost two decades and is about 25 kilometers (16 miles) from Basco.
• Ruins Of Songsong is a ghost barangay which is a cluster of roofless shells of old stone houses abandoned after a tidal wave that hit the island of Batan in the 1950s. It has a long stretch of beach. The ruins are 23 kilometers (14 miles) from Basco.
• San Jose Church in Ivana was built in 1814. It has a crenelated fortress-like campanile. The church fronts the Ivana Seaport and is 14 kilometers (8.7 miles) from Basco.
• Kanyuyan Beach & Port at Baluarte Bay in Basco is the port of call of the cargo ships bringing goods from Manila.
• San Carlos Borromeo Church and a convent at Mahatao are six kilometers (3.7 miles) from Basco. It was completed in 1789 and still retains its centuries-old features.
• Idjangs or fortified stone fortresses where the native Ivatans' ancestors migrated to Batanes as early as 4,000 BC lived in them for defensive cover.
• Fundacion Pacita is a lodging house and restaurant, which was formerly owned by Pacita Abad, the most iconic Ivatan visual artist. The house has been redecorated and filled with numerous art works of Pacita Abad after she died in 2004.

• Radiwan Point at Ivana Seaport is where the Katipuneros landed on September 18, 1898. It is also the ferry station of the falowas plying the islands of Sabtang and Itbayat.
