Haiti (French: Haïti, Haitian Creole: Ayiti), officially the Republic of Haiti (République d'Haïti ; Repiblik Ayiti), is a Creole- and French-speaking Caribbean country. Along with the Dominican Republic, it occupies the island of Hispaniola, in the Greater Antillean archipelago. Ayiti (Land of high mountains) was the indigenous Taíno or Amerindian name for the mountainous western side of the island. The country's highest point is Pic la Selle, at 2,680 metres (8,793 ft). The total area of Haiti is 27,750 square kilometres (10,714 sq mi) and its capital is Port-au-Prince.

Haiti's regional, historical, and ethnolinguistic position is unique for several reasons. It was the first independent nation in Latin America, the first post-colonial independent black-led nation in the world, and the only nation whose independence was gained as part of a successful slave rebellion. Despite having common cultural links with its Hispano-Caribbean neighbors, Haiti is the only predominantly Francophone independent nation in the Americas, and one of only two (along with Canada) which designate French as an official language; the other French-speaking countries are all overseas départements or collectivités of France.
