West Bandung Regency (Kabupaten Bandung Barat) is a landlocked regency of West Java. It was established on 2 January 2007, having been formerly part of Bandung Regency. The capital of this new regency is Ngamprah, an industrial district on the west side of Bandung. The entire regency is all part of the Bandung Metropolitan Area.

The area of the regency is 1,287.41 km and the population was 1,506,448 at the 2010 Census and 1,788,336 at the 2020 Census. The official estimate as at mid 2023 was 1,859,636 - comprising 948,045 males and 911,591 females.

The idea of dividing Bandung Regency into two separate regencies originated in 1999, based on a proposal from the current regent (H.U. Hatta Djati Permana) for the parliament to consider and approve the idea of splitting off the western part of the existing Bandung Regency. Before the split-off was successfully completed, the Bandung suburb of Cimahi (an area consisting of three districts, which used to be part of Bandung Regency) had been promoted in 2001 to become an autonomous city. After Cimahi became an autonomous administration, the request to split off the western portion of Bandung Regency as a separate regency grew.

Finally in 2006, the government of Indonesia approved the proposal to separate the western part of Bandung Regency to become a separate regency, the West Bandung Regency. On its birth on 2 January 2007, this new regency in West Java were headed by an appointed acting regent H. Tjatja Kuswara (an officer from West Java provincial government) until April 2008, when the first direct election of West Bandung Regency Regent was held, with H. Abubakar and H. Agus Yasmin as the contestants; H. Abubakar with his running mate Ernawan Natasaputra won the election and became the Regent and Vice-Regent of West Bandung Regency.

West Bandung Regent currently is Hengky Kurniawan.

At the time of the 2010 Census, West Bandung Regency was divided into fifteen districts (kecamatan), but in October 2011 a sixteenth district (Saguling) was created by the division of the existing Batujajar District. Parongpong and Lembang Districts lie immediately north of Bandung city, and contain many suburbs of the city. The districts (which each bears the name of the town which is its administrative centre) are all listed below with their areas and their populations at the 2010 Census and the 2020 Census, together with the official estimates as at mid 2023 (the latter rounded to the nearest 100 persons). The districts each have the same name as the town that is its administrative centre. The table also includes the number of administrative villages in each district (all 165 classed as rural desa), and its post code(s).
