The Batu Islands are an archipelago of Indonesia located in the Indian Ocean, off the west coast of Sumatra, between Nias and Siberut. The three primary islands, of approximately equal size, are Pini, Tanahmasa, and Tanahbala. There are seventy-five smaller islands, of which the largest are Sipika, Tello and Sigata (all off the west coast of Tanahmasa), Simuk (considerably further to the west) and Bojo (to the south of Tanahbala); less than half are inhabited. The total land area of the seven administrative districts is 1,201.1 km2. The islands are governed as a part of South Nias regency within North Sumatra province. In Indonesian and Malay, batu means rock or stone.
The equator passes through the archipelago, north of Tanahmasa and south of Pini. Administratively, Pini (with offshore islets) forms the Pulau Pulau Batu Timur (East Batu Islands) District of South Nias Regency. The rest of the archipelago at the 2010 Census formerly comprised the Pulau Pulau Batu (Batu Islands) and Hibala Districts of the same regency; however, both have been subsequently divided to form new Districts - Tanahmasa District has been formed from part of Hibala District, and three new districts have been formed from parts of Pulau Pulau Batu District - namely Pulau Pulau Batu Barat (West Batu Islands), Pulau Pulau Batu Utara (North Batu Islands, which lie to the north of Tanamasa) and Simuk Districts. The original districts remain with reduced areas and population, and thus the islands now form seven separate districts.
