Morotai Island (Indonesian:Pulau Morotai) is an island in the Halmahera group of eastern Indonesia's Maluku Islands (Moluccas). It is one of Indonesia's northernmost islands.

Morotai is a rugged, forested island lying to the north of Halmahera. It has an area of some 1,800 square kilometres (690 sq mi), stretching 80 kilometres (50 mi) north-south and no more than 42 kilometres (26 mi) wide. The island's largest town is Daruba, on the islands south coast. Almost all of Morotai's numerous villages are coastal settlements; a paved road linking those on the east coast starts from Daruba and will eventually reach Berebere, the principal town on Morotai's east coast, 68 kilometres (42 mi) from Daruba. Between Halmahera and the islets and reefs of the west coast of Morotai is the Morotai Strait, which is about 10 kilometres (6.2 mi) wide.
