Pulau Reni is a small Indonesian island located in the Ayu Archipelago above the northern tip of the Waigeo Islands.

Pulau Reni is part of the Raja Ampat regency of the Southwest Papua geographical and administrative region of Indonesia.

Access to the island is limited to small boats due to the reefs and the small size of the island.

Pulau Reni and all the islands in the Ayu Archipelago were occupied by the Japanese Empire during World War II from 1942 until the end of the war in 1945.
