Sulawesi (formerly known as Celebes /ˈsɛlɨbiːz/ or /sɨˈliːbiːz/) is one of the four larger Sunda Islands of Indonesia 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 Indonesian populations.
Sulawesi has a distinctive shape, dominated by four large narrow peninsulas: the north Semenanjung Minahassa; 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 while South and Southeast Peninsula. The Strait of Makassar runs along the western side of the island and separates the island from Borneo.
