A mukim is the second-level administrative division of Brunei Darussalam, positioned below districts (daerah) and above villages (kampung). Each mukim is headed by a penghulu, who has been democratically elected since 2015. Mukims function as important administrative units for governance, census, and community coordination.
As of recent records, Brunei has 39 mukims distributed across its four districts.
