Waigeo is an island in West Papua province of eastern Indonesia. The island is also known as Amberi, or Waigiu. It is the largest of the four main islands in the Raja Ampat Islands archipelago, between Halmahera and about 65 kilometres (40 miles) to the north-west coast of New Guinea. The Dampier Strait (a.k.a. Augusta's Strait) separates it from Batanta, and the Bougainville Strait from the Kawe Islands to its north-west. The "inner sea" that nearly cleaves the island in two is the Majoli Gulf.
