Mangareva is the central and largest island of the Gambier Islands in French Polynesia. It is surrounded by smaller islands: Taravai in the southwest, Aukena and Akamaru in the southeast, and islands in the north. Mangareva has a permanent population of 1,239 (2012) and the largest village on the island, Rikitea, is the chief town of the Gambier Islands.

The island is approximately eight kilometres (5 mi) long and, at 15.4 km² (5+15⁄16 sq mi), it comprises about 56% of the land area of the whole Gambier group. Mangareva has a high central ridge which runs the length of the island. The highest point in the Gambiers is Mount Duff, on Mangareva, rising to 441 metres (1,447 ft) along the island's south coast. The island has a large lagoon 24 kilometres (15 mi) in diameter containing reefs whose fish and shellfish helped ancient islanders survive much more successfully than on nearby islands with no reefs.
