Tikehau is a small coral atoll in the Tuamotu Archipelago of French Polynesia, northeast of Tahiti. Its oval lagoon is enclosed by a narrow chain of coral islets known as motu, with only a few channels connecting the lagoon to the open Pacific. Most of the land is low and covered with coconut palms, coastal vegetation, and white- and pink-tinged sand. The main inhabited area is Tuherahera, located on the southern edge of the atoll, where a small community lives among gardens, coconut groves, and beaches.

Tikehau's culture is closely connected to traditional Polynesian life and the resources of the lagoon. Fishing and coconut cultivation remain important, while local families maintain knowledge of reef conditions, marine species, and traditional food preparation. Tuherahera is the main village and contains the atoll's church and community facilities. Like other Tuamotu communities, Tikehau has a strong relationship with the sea, which has historically provided food and supported travel between islands. Small-scale local tourism has developed alongside these traditions without creating a large urban center.

The lagoon is Tikehau's principal natural feature, supporting extensive coral reefs and a wide range of marine life. The atoll is known for its underwater environment, with diving and snorkeling sites where visitors can encounter reef fish, rays, sharks, turtles, and other marine species. Bird Island, a group of small motu and sandbanks in the lagoon, provides nesting habitat for seabirds and can be reached by boat. The atoll's low elevation makes its landscape quite different from the mountainous islands of French Polynesia, with broad horizons, shallow lagoon waters, and coral beaches defining the scenery.

Food on Tikehau centers on seafood and ingredients that can be grown in the atoll's limited soil. Fresh fish, coconut, taro, breadfruit, bananas, and other tropical produce feature in local meals. Poisson cru, raw fish marinated with lime and combined with coconut milk and vegetables, is a familiar Polynesian preparation. Coconut is also used in sauces, desserts, and drinks, while locally caught fish may be grilled or prepared in other simple ways. Tikehau is particularly associated with pearl farming, an important industry throughout the Tuamotu Islands, where black-lipped oysters are cultivated in sheltered lagoon waters.
