West Kotawaringin Regency (Indonesian: Kabupaten Kotawaringin Barat) is one of the thirteen regencies which comprise the Central Kalimantan Province on the island of Kalimantan (Borneo), Indonesia. It originally comprised the whole western part of the province, having been split from a single Kotawaringin Regency on 26 June 1959 into separate regencies for West and East Kotawaringin, but on 10 April 2002 the most westerly districts of West Kotawaringin were split off to form the new Lamandau Regency and Sukamara Regency. The residual West Kotawaringin Regency has a land area of about 10,759 km2, and its population was 235,803 at the 2010 Census and 270,388 at the 2020 Census; the official estimate as at mid 2024 was 282,790 (comprising 146,120 males and 136,670 females). The large town of Pangkalan Bun in Arut Selatan District is the capital of West Kotawaringin Regency.
