The Obi Islands (also known as Ombirah,[1] Indonesian: Kepulauan Obi) are a group of 42 islands in the Indonesian province of North Maluku, north of Buru and Ceram, and south of Halmahera. With a total area of 3,048.08 km2, they had a population of 41,455 at the 2010 Census[2] and 50,760 at the 2020 Census.[3] The official estimate as at mid 2022 was 52,588.[4]
Obi Island, also called Obira Island, is the largest island in the Obi Islands archipelago. It is surrounded by many small islands, including Bisa Island (174.42 km2), Obilatu Island (65.30 km2), Gata-gata Island, Latu Island, Woka Island, and Tomini Island. Obi Island is bordered by the Maluku Sea to the west, the Seram Sea to the south, and the Obi Strait to the north and east. The major islands closest to it are Bacan Island to the north and Ambon to the south. Obi Island's topography is generally in the form of hills with a short coastline. The hilly surface results in many springs and rivers. Lake Kapi, in the west, is its largest lake. The area was historically abundant in sago and fish.[5][6]
The Obi Islands were an independent kingdom during the 14th century, who were near-equal in importance with the other Malukuan kingdoms (Jailolo, Bacan, Ternate, Tidore), and often intermarried with the family of Ternate.[5] However, at some point Obi became subject to Bacan.[5][6] A decline in Bacan's population possibly caused the transfer of Obi's population to Bacan, which left the islands uninhabited by the mid-17th century.[5]
On May 9, 1682,[7] Obi, Obilatu, Gomumu, Tapat, and Bisa were sold by the Sultan of Bacan to the VOC for 620 rijksdaalder.[8] The islands became a center for the Tobelo chiefs, and many Tobelo and Galela moved to the islands.[9] In 1876, the islands were declared government property.[10]
The Obi Islands are part of South Halmahera Regency. The archipelago is directly bordered by the rest of North Maluku Province to the north and west, by Maluku Province in the south and by West Papua Province in the east. The total area of the main island is about 2,800 square kilometres (1,100 sq mi). Obi Island and the surrounding small islands are divided into five administrative districts (kecamatan), which are sub-divided into 34 administrative villages (desa and kelurahan), with villages further subdivided into hamlets. Of the five districts, three comprise the main Obi Island, although each district also includes neighbouring smaller islands - Obi District includes the southern part of Bisa Island to the north of Obi Island, Obi Timur District includes Tobalai Island to the east, and Obi Selatan Island also includes Gomumu Island to the south. The other two districts include no part of Obi Island; Obi Barat District includes Obilatu and Belangbelang Islands to the west of Obi Island, together with the southern part (Tapa desa) of Tapat Island, while Obi Utara District includes the main part of Bisa Island to the north of Obi Island, together with the northern part (Pasir Putih desa) of Tapat Island.
The population of the Obi Islands Group was 52,588 people in mid 2022,[11] with a population density of 17.25 people per square kilometre.[12] All inhabitants on the Obi Island are migrants, as these islands had no indigenous population. The first groups to settle on Obi Island were the Buton, followed by immigrants from Tobelo-Galela, Ternate, Tidore, Makian-Kayoa, Bugis, Makassar and Java.[citation needed] Almost all of the residents are scattered along the coast with the highlands mostly uninhabited jungle. However, there are some worker settlements in hilly areas which have mines and temporary settlements for clove farmers used during clove harvesting season. Infrastructure, especially in terms of modern medical facilities, is lacking.[citation needed]
The languages spoken on the islands are Galela and Tobelo, which belong to the West Papuan language family.[citation needed]
The five districts are sub-divided into villages (rural desa and urban kelurahan), listed below with their areas and their populations at the 2020 Census.[13] The administrative centres of the five districts are denoted by asterisks.

The dominant plantation products in the Obi Islands are cloves, nutmeg, coconut, and pepper. The main economic potential of the islands s in the mining sector. The island has resources of gold, coal, nickel, cement, and petroleum. In 2016, provincial governor Abdul Ghani Kasuba successfully negotiated for the China-based Jinchun Group to build a 620 million dollar nickel smelter on the main island.[15]
