The Chagos Archipelago ( /ˈtʃɑːɡoʊs/ or /ˈtʃɑːɡəs/; formerly Bassas de Chagas and later also Oil Islands, known as Foalhavahi ފޯޅަވަހި in Dhivehi, as Phehandweep फेहंद्वीप in Hindi and other North Indian languages, and as Paeikaana Theevukal பேகான தீவுகள் in Tamil), is a group of seven atolls comprising more than 60 individual tropical islands in the Indian Ocean; situated some 500 kilometres (310 mi) due south of the Maldives archipelago. This chain of islands are the southernmost archipelago of the Chagos-Laccadive Ridge a long submarine mountain range in the Indian Ocean. The Chagos also form a terrestrial ecoregion together with the Maldives and the Lakshadweep. The islands and their surrounding waters are also a vast oceanic Environment Preservation and Protection Zone (EPPZ) (Fisheries Conservation and Management Zone (FCMZ) of 544,000 square kilometres (210,000 sq mi)), an area twice the size of the UK's land surface.

Officially part of the British Indian Ocean Territory, the Chagos were home to the Chagossians for more than a century and a half until the United Kingdom evicted them in the early 1970s in order to allow the United States to build a military base on Diego Garcia, the largest of the Chagos Islands. Since 1971, only the atoll of Diego Garcia is inhabited, and only by military and civilian contracted personnel.
