Buru Regency is a regency of Maluku province, Indonesia. When it was first created on 4 October 1999 (by separation from Central Maluku Regency), the regency encompassed the entire island (plus outlying islands); but on 24 June 2008 the southern 40% of the island was split off to form a separate Buru Selatan (South Buru) Regency. The residual Buru Regency comprises the northern 60% of the island of Buru and covers an area of 7,595.58 km2. The population at the 2010 census was 108,445[2] and at the 2020 census this had increased to 135,238;[3] the official estimate as at mid 2023 was 139,408 (comprising 70,598 males and 68,810 females).[4] The principal town lies at Namlea.
At the time of the 2010 census the Buru Regency was divided into five districts (kecamatan), but subsequently this has been increased to ten districts by the splitting of the existing districts. The ten districts are tabulated below with their areas and their populations at the 2010 census[5] and the 2020 census,[6] together with the official estimates as at mid 2023.[7] The table also includes the location of the district headquarters, the number of administrative villages (all classed as rural desa) in each district, and its postal codes.
