Futuna is an island in the Tafea province of Vanuatu. It is the easternmost island in the country. It was formed by the uplift of an underwater volcano, which last erupted in the Pleistocene, at least 11,000 years ago. It reaches a height of 666 m. It is sometimes called West Futuna to distinguish it from Futuna Island, Wallis and Futuna. It is a Polynesian outlier.

It has ten regions: Iraro, Itapapa, Itapasiesi, Matangi, Matowei, Nabao, Nariari, Rakaoroa, Serinao, and Tchinaroa.

The inhabitants of the island have a style of hymn singing, established by 19th century missionaries, which is distinctive among Pacific islands.
