Sulawesi is an island in Indonesia. One of the four Greater Sunda Islands, and the world’s eleventh-largest island, it is situated between Borneo and the Maluku Islands. In Indonesia, only Sumatra, Borneo, and Papua are larger in territory, and only Java and Sumatra have larger populations.
Sulawesi comprises four peninsulas: the northern Minahassa Peninsula; the East Peninsula; the South Peninsula; and the South-east Peninsula. Three gulfs separate these peninsulas: Gulf of Tomini between northern Minahassa peninsula and East Peninsula; Tolo Gulf between East and Southeast Peninsula; and Bone Gulf between the South and Southeast Peninsula. The Strait of Makassar runs along the western side of the island and separates the island from Borneo.
