The Southeast Peninsula is a peninsula of Sulawesi (Celebes), lying between the Gulf of Tolo and the Gulf of Boni. It is mostly coterminous with the province of Southeast Sulawesi. The largest city on the peninsula is Kendari.
Several islands are situated off its south-eastern tip, including Muna and Buton.
Sulawesi (/ˌsuːləˈweɪsi/ SOO-lə-WAY-see, Indonesian: [ˌsulaˈwesi]), also known as Celebes (/ˈsɛlɪbiːz, səˈliːbiːz/ SEL-ib-eez, sə-LEE-beez), is an island in Indonesia. One of the four Greater Sunda Islands, and the world's 11th-largest island, it is situated east of Borneo, west of the Maluku Islands, and south of Mindanao and the Sulu Archipelago. Within Indonesia, only Sumatra, Borneo, and Papua are larger in territory, and only Java and Sumatra are more populous.
The landmass of Sulawesi includes four peninsulas: the northern Minahasa Peninsula, the East Peninsula, the South Peninsula, and the Southeast Peninsula. Three gulfs separate these peninsulas: the Gulf of Tomini between the northern Minahasa and East peninsulas, the Tolo Gulf between the East and Southeast peninsulas, and the Gulf of Boni between the South and Southeast peninsulas. The Strait of Makassar runs along the western side of the island and separates the island from Borneo.
