Buton Regency

Buton Regency (Kabupaten Buton) is a regency of Indonesia's Southeast Sulawesi Province, lying entirely on Buton Island. Until 2014 it had an area of 2,681.22 km², and a population estimated at 276,944 (for January 2014). However, in 2014 it was divided into three regencies, with two new regencies being cut out of it; the residual area now is 1,648.04 km², and the districts in that area contained a population of 94,388 at the 2010 Census while the 2020 Census produced a total of 115,207; the official estimate as at mid 2022 was 119,353 (comprising 60,252 males and 59,101 females).

The capital is nominally at Pasarwajo, but the administrative centre is in the city of Baubau on the south-west of the island, although that city is administratively separate from the Regency.
