Annobón (Spanish: [anoˈβon] ; Portuguese: Ano-Bom) is a province of Equatorial Guinea. The province consists of the island of Annobón and its associated islets in the Gulf of Guinea. Annobón is the smallest province of Equatorial Guinea in both area and population. According to the 2015 census, Annobón had 5,323 inhabitants, a small population increase from the 5,008 registered by the 2001 census. The official language is Spanish but most of the inhabitants speak a creole form of Portuguese. The island's main industries are fishing and forestry.
Annobón is the only island of the country located in the Southern Hemisphere of the Atlantic Ocean. The provincial capital is San Antonio de Palé on the north side of the island. There are three other small settlements; Mabana, San Pedro and Aual. As of 1911, some passing ships visited for water and fresh provisions, of which Annobón offered an abundant supply. However, there was no regular shipping service to the rest of Equatorial Guinea, and ships called as infrequently as every few months.
