When Ketapang Regency was originally created, it consisted of the twelve districts of Kendawangan, Manis Mata, Marau, Singkup, Tumbang Titi, Matan Hilir, Nanga Tayap, Sandai, Simpang Hilir, Simpang Hulu, Sukadana and Maya Karimata Islands. In 1988, Matan Hilir district was divided into two districts, namely Matan Hilir Utara and Matan Hilir Selatan. On 17 June 1996, Teluk Batang district was established by split off from the western part of Simpang Hilir district. In 2003, five new districts were established; Delta Pawan (equating to Ketapang town) and Muara Pawan districts were split off from the southern part of Matan Hilir Utara district, Benua Kayong district was split off from northern part of Matan Hilir Selatan district, Hulu Sungai district was split off from eastern part of Sandai district, Simpang Dua was split off from the southern part of Simpang Hulu district, Air Upas and Singkup districts were split off from the southeastern and southwestern parts of Marau district, respectively. In 2005, another three new districts were created (Seponti district was cut out from the northwestern part of Teluk Batang district, Pemahan and Sungai Melayu Rayak districts were cut out from the northern and western parts of Tumbang Titi district, respectively). In 2007, a new district named Jelai Hulu was carved out from the northeastern part of Kendawangan district.
Following the splitting off of the five districts to form the North Kayong Regency in January 2007, the Ketapang Regency now consists of twenty districts (kecamatan), tabulated below with their areas and their populations at the 2010 census[2] and the 2020 census;[3] together with the official estimates as at mid 2025.[1] In this table they are grouped for convenience into three geographical sectors (which have no administrative significance): a more rapidly growing southern sector ("Kayong Selatan") covering six districts, where the Kendawangan dialect is the usual linguistic constant; a central well-populated but geographically smaller sector ("Kayong Tengah") covering nine districts based on the Pawan River Estuary and the regency capital of Ketapang town; and an (inland) north-eastern sector ("Kayong Timur") covering just five districts with a much more sparse population. The table includes the locations of the district administrative centres, the number of administrative villages in each district (totaling 253 rural desa and 9 urban kelurahan, the latter all in the urban area (kawasan perkotaan) of Ketapang town), and their post codes.
