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 km to the northwest 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 northwest. The "inner sea" that nearly cleaves the island in two is the Majoli Gulf.
