Mempawah Regency (formerly called the Pontianak Regency) is a regency of West Kalimantan Province of Indonesia. Originally including a wider area of West Kalimantan, this Pontianak Regency was reduced on 4 October 1999 by the north-eastern districts (formerly the majority of the regency's land area) being removed to form a new Landak Regency, and was further reduced on 17 July 2007 by its southern districts cut out to create a new Kubu Raya Regency. Since 2007 the residual regency (now renamed Mempawah Regency) covers 1,935.42 km2, and had a population of 234,021 at the 2010 Census[2] and 301,560 at the 2020 Census;[3] the official estimate as at mid 2023 was 312,785 (comprising 159,986 males and 152,799 females).[4] The administrative centre is at the town of Mempawah.
Based on Government Regulation No. 58 of 2014 (Peraturan Pemerintah Nomor 58 Tahun 2014), Pontianak Regency was formally renamed Mempawah Regency after the name of its administrative centre.[5]
Since the separation of the southern parts of the former Pontianak Regency on 17 July 2007 to form the new Kubu Raya Regency, the residual area - in 2014 renamed as Mempawah Regency - consists of nine districts (kecamatan), tabulated below with their areas and their populations at the 2010 Census[6] and the 2020 Census,[7] together with the official estimates as at mid 2023.[8] The table also includes the locations of the district administrative centres, the number of administrative villages in each district (a total of 60 rural desa and 7 urban kelurahan), and its post code.
