Wallis and Futuna, officially the Territory of the Wallis and Futuna Islands (French: Wallis et Futuna or Territoire des îles Wallis et Futuna, Fakauvea and Fakafutuna: Uvea mo Futuna), is a Polynesian French island territory in the South Pacific between Tuvalu to the northwest, Rotuma of Fiji to the west, the main part of Fiji to the southwest, Tonga to the southeast, Samoa to the east, the New Zealand-associated state of Tokelau to the northeast and to a more distant north the Phoenix Islands (Kiribati). (However, Wallis and Futuna is not part of, nor even contiguous with, French Polynesia. Wallis and Futuna is located at the very opposite western end of Polynesia.)

Its land area is 264 km² with a population of about 15,000. Mata-Utu is the capital and biggest city. The territory is made up of three main volcanic tropical islands along with a number of tiny islets, and is split into two island groups that lie about 260 km apart, namely Wallis Islands (Uvea) in the northeast, and Hoorn Islands (also called the Futuna Islands) in the southwest, including Futuna Island proper and the mostly uninhabited Alofi Island.
