The Juan Fernández Islands (Spanish: Archipiélago Juan Fernández) are a sparsely inhabited island group reliant on tourism and fishing in the South Pacific Ocean, situated about 667 km (360 nmi; 414 mi) off the coast of Chile, and is composed of several volcanic islands:
The islands are mainly known for having been the home to the sailor Alexander Selkirk for four years, which may have inspired the novel Robinson Crusoe. The islands have an area of 181 km2 (70 sq mi), of which 93 km2 (36 sq mi) are taken up by Robinson Crusoe (together with Santa Clara), and 33 km2 (13 sq mi) by Alexander Selkirk. The population is 633 (all on Robinson Crusoe); of those 598 reside in the capital, San Juan Bautista, on Cumberland Bay on the north coast of the island (2002 census).
The archipelago administratively belongs to Chile's Valparaíso Region (which also includes Easter Island), and more specifically forms one of the nine communes (comunas) of the Valparaíso Province named Juan Fernández.
