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.
