The Tuamotu Archipelago or the Tuamotu Islands are a French Polynesian chain of just under 80 islands and atolls in the southern Pacific Ocean. They constitute the largest chain of atolls in the world, extending over an area roughly the size of Western Europe. Their combined land area is 850 square kilometres. This archipelago's major islands are Anaa, Fakarava, Hao and Makemo.

French Polynesia is an overseas collectivity of France and its sole overseas country. It comprises 121 geographically dispersed islands and atolls stretching over more than 2,000 kilometres (1,200 mi) in the South Pacific Ocean. The total land area of French Polynesia is 3,521 square kilometres (1,359 sq mi), with a population of 278,786 of which at least 205,000 live in the Society Islands and the remaining population lives in the rest of the archipelago.
