The Babuyan Islands ( ), also known as the Babuyan Group of Islands, is an archipelago in the Philippines, located in the Luzon Strait north of the main island of Luzon and south of Taiwan via Bashi Channel to Luzon Strait. The archipelago consists of five major islands and their surrounding smaller islands. These main islands are, counterclockwise starting from northeast, Babuyan, Calayan, Dalupiri, Fuga, and Camiguin. The Babuyan Islands are separated from Luzon by the Babuyan Channel, and from the province of Batanes to the north by the Balintang Channel.
Geography
The archipelago, comprising 24 volcanic-coralline islands, has a total area of about . The largest of these is Calayan with an area of , while the highest peak in the island group is Mount Pangasun () on Babuyan Claro.

Geology
The eastern islands of the archipelago are part of the Luzon Volcanic Arc. Three volcanoes from two of the islands have erupted in historical times - Camiguin de Babuyanes on Camiguin Island, Babuyan Claro Volcano and Smith Volcano (also known as Mount Babuyan) on Babuyan Island.
Another small volcanic island located just NE of Camiguin Island, Didicas Volcano on Didicas Island, became a permanent island only after emerging and rising to over above sea level in 1952.
Flora and fauna
All of the islands within the island group are classified by Haribon Foundation and BirdLife International as key biodiversity areas, or sites with outstanding universal value due to its geographic and biologic importance. All of the islands within the island group have never been part of any large landmass, and thus have unique flora and fauna, most of which are found nowhere else. A research conducted by the Department of Environment and Natural Resources have found at least 5 faunal regions in the area, one of the highest density of separate faunal regions in the world. The islands are also home to the most critically endangered bird species in the Philippines, the Calayan rail (found only on the small island of Calayan), and the most critically endangered snake species in the Philippines, the Ross' wolf snake (found only on the small island of Dalupiri). The island group is also a congregation site for endangered humpback whales, one of the only few of its kind in Southeast Asia. Due to its immense value to the natural world and Philippine biological diversity, various scientific and conservation groups have been lobbying for its declaration as a national park and its inclusion in the UNESCO World Heritage List.
Humpback whales have re-colonized into the area and the Babuyan became the only wintering ground for the species in the Philippines although historical records among Babuyan Islands have not been confirmed.
