East Kotawaringin Regency


East Kotawaringin Regency is one of the thirteen regencies which comprise the Central Kalimantan Province on the island of Kalimantan, Indonesia. It originally covered a much larger part of the province, having been split from a single Kotawaringin Regency on 26 June 1959 into separate regencies for East and West Kotawaringin, but on 10 April 2002 several districts in the west of the regency were split off to form the new Seruyan Regency, and several districts in the east of the regency were similarly split off to form the new Katingan Regency. The area of the residual East Kotawaringin Regency is 15,541.75 km2, and its population was 374,175 at the 2010 Census, and 428,900 at the 2020 Census; the official estimate as at mid 2024 was 448,180. The town of Sampit is the capital of East Kotawaringin Regency.

Geography

The residual regency is essentially the catchment area of the Mentaya River. The large town of Sampit lies on the west bank of the river; its metropolitan area encompasses most of Mentawa Baru Ketapang District and all of Baamang District, plus a part of Seranau District.

Administrative districts

At the 2010 Census, East Kotawaringin Regency consisted of fifteen districts, but two more districts were subsequently established by the splitting of existing districts. The seventeen districts are tabulated below with their areas and population totals from the 2010 Census and the 2020 Census, together with the official estimates as at mid 2024. The table also includes the locations of the district administrative centres, the number of administrative villages in each district, and its postal codes.
