East Kotawaringin Regency (Indonesian: Kabupaten Kotawaringin Timur) is one of the thirteen regencies which comprise the Central Kalimantan Province on the island of Kalimantan (Borneo), Indonesia. It originally covered a much larger part of the province, 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 population of the residual East Kotawaringin Regency was 374,175 at the 2010 Census, and 428,900 at the 2020 Census; the official estimate as at mid 2022 was 436,079 (comprising 224,238 males and 211,841 females). The town of Sampit is the capital of East Kotawaringin Regency.
At the 2010 Census, East Kotawaringin Regency consisted of fifteen districts (kecamatan), but two more districts (Tualan Hulu and Telaga Antang) 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 2022. The table also includes the locations of the district administrative centres, the number of administrative villages in each district (totaling 168 rural desa and 17 urban kelurahan), and its postal codes.
