Bora Bora is an island in the Leeward group of the Society Islands of French Polynesia, an overseas territory of France in the Pacific Ocean. The island, located about 260 km northwest of Papeete (French Polynesia's capital), is surrounded by a lagoon and a fringing reef. In the center of the island are the remnants of an extinct volcano, rising to two peaks, Mt. Pahia, and the highest point, Mount Otemanu, reaching 727 meters (2,385 ft.).

The island is administratively part of the commune (municipality) of Bora-Bora, itself in the administrative subdivision of the Leeward Islands.

As of 2002, the population was about 7,250 people. The major settlement, Vaitape is on the western side of the island, opposite the main channel into the lagoon.

The original name in the Tahitian language might be better rendered as Pora Pora, meaning "First Born".

The products of the island are mostly limited to what can be obtained from the sea and coconut trees.
