Maiao, also known as Mai'ao, is an 8.8 km2 (3.4 sq mi) island formation located 78 km (48 mi) southwest of Mo'orea and one of the Windward Islands (French: Îles du Vent) in French Polynesia.
The island formation consists of one high island with a peak elevation of 154 meters (505') and a low island (or motu) that winds along the base of the high island. The formation encloses two hypersaline lagoons called Roto Iti and Roto Rahi. The island also has a lagoon at its edge. All lagoons are connected through narrow channels. The island is home to 2 people (as of Aug. 2007 census).
The island is administratively part of the commune (municipality) of Mo'orea-Mai'ao, itself in the administrative subdivision of the Windward Islands.
