Buton (also Butung, Boeton or Button) is an island in Indonesia located off the southeast peninsula of Sulawesi.

Major nearby islands include Wawonii (to the north), Muna and Kabaena (to the west) and Siumpu (to the southwest).

Also the Bouton Passage (as it was known in the pre-Independence era) was an important inter-island navigational location of the northern Flores Sea.

The languages spoken on Buton include Wolio, Cia-Cia, various dialects of Muna, Tukang Besi, Kumbewaha, Lasalimu, Kamaru, Pancana, Busoa, Taloki, Kulisusu and Kioko.

As a result, natural asphalt can be used to reduce dependency on conventional fossil based resources.
