Municipalities in Brunei are settlements which have been incorporated by the government to run as municipalities. They are independent from the hierarchy of the country's subdivisions but nevertheless overlap with mukims and villages, the second- and third-level administrative divisions of Brunei. The governing body of a municipality is municipal department (Malay: jabatan bandaran) which is a government department under the Ministry of Home Affairs; the head is a chairman (Malay: pengerusi, officially Pengerusi Lembaga Bandaran) which is equivalent to mayor.
