Apataki, Coral atoll in the Palliser Islands, Tuamotu Archipelago, French Polynesia

Apataki is a coral atoll of the Palliser Islands in the Tuamotu Archipelago, roughly rectangular and about 34 km long and 24 km wide. Its land area of some 21 km2 is divided among about thirty motu, which enclose a 706 km2 lagoon entered by two main passes. The main village, Niutahi, lies in the south.

Dutch navigator Jakob Roggeveen reached Apataki in 1722 and named it Hagemeister Island. James Cook visited on 19 April 1774 and attached the atoll to the Palliser group. In 1852 the parish of Saint-Philippe was founded, and a new church of the same name was built in 1974 under the Diocese of Papeete.

Apataki's 442 residents live mainly in Niutahi, in the south of the atoll. The parish of Saint-Philippe was founded in 1852, and a new church of the same name was built in 1974. Pandanus leaves are still woven into roof thatch, mats and hats.

Apataki Airport (code APK), inaugurated in 1977, sits beside Niutahi; its runway is 950 m long and handles about 300 flights and 1,500 passengers a year. There are no land-based accommodations, so visitors stay on charter boats. The atoll's only shop is the Pahai grocery, stocked from Tahiti. The boatyard on motu Tamaro stores and repairs vessels up to 20 tonnes.

On 27 May 1902 the mail-boat Croix du Sud, running between Papeete and Atuona, was wrecked at Apataki while Paul Gauguin was living in the Marquesas. The islanders lost their supplies for three months. The atoll also appears on some maps as "Hagemeister Island", the name Jakob Roggeveen gave it in 1722.
