Obira (also called Utara or Obi) is the main island in the Obi Islands group, in Indonesia, south of the larger Halmahera in North Maluku. Its area is 2,542 km².

The island is eponymous to the Obi Island Birdwing, an endemic species of butterfly.[1] Due to extensive logging on the island, which has reduced its habitat, the conservation of this species is a concern.

In 2016, provincial governor Abdul Ghani Kasuba successfully negotiated with the China-based Jinchun Group for the building of a nine-trillion rupiah nickel smelter on the island.[2]
