A mukim (Jawi: مقيم from Arabic مقيم muqīm "residence") is a type of administrative division used in Malaysia, Brunei, Indonesia and Singapore, equivalent to a subdistrict.
In Brunei, a mukim is the immediate subdivision of a district (Malay: daerah). The equivalent English word for 'mukim' is 'township'. There are 38 mukims in Brunei. Each mukim is an administrative area made up of several villages (kampung). A mukim is headed by a headman (penghulu), which is an elected office. The number of mukims in each of the districts in Brunei is as follows:
| District | Number of Mukims | Map |
|---|---|---|
| Belait | 8 | |
| Brunei-Muara | 17 | |
| Temburong | 5 | |
| Tutong | 8 |
The smallest mukim by area is Mukim Saba in the Brunei-Muara District. The largest mukim by area is Mukim Sukang in the Belait District. The last change in the mukim boundaries was in the late 1990s when Mukim Kumbang Pasang was merged into Mukim Kianggeh and Mukim Berakas was divided into Mukim Berakas A and Mukim Berakas B. The number of mukims remained at 38.
The term mukim is used only in the autonomous province of Aceh as a subdivision of a district (kecamatan). A mukim contains several villages (gampong).[citation needed]
In Malaysia, a mukim of almost all constituent states except Perlis, Kelantan, Sabah and Sarawak can either be a subdivision of a daerah (district or county) or a subdivision of an autonomous sub-district (daerah kecil), as per Section 11(c) of the 1965 National Land Code. Each mukim comprises one or several villages (kampung) with a population between 4,000–200,000 people represented with a mosque or surau as a communal centre; it may overlap with residential neighbourhoods (taman perumahan or taman for short) in urban areas. Mukim may be translated roughly in English to townships.
The northern state of Perlis, due to its small size, is not divided into daerahs, but directly into mukims. In Kelantan, the term daerah corresponds equally to the mukim as subdivisions of a jajahan; whilst Sarawak and its large size in East Malaysia are directly divided into divisions and in turn, divisions are divided into districts and the subdivision of each district is termed as a land district (daerah tanah) or town district (daerah bandar) instead. The neighbouring state of Sabah does not have such subdivisions, districts serve instead as the lowest jurisdictional level. In the federal territory of Putrajaya, "precincts" (presint) are the equivalent to the mukim.
In Singapore, a mukim is a survey district. There are 30 town subdivision survey districts located in the central city area surrounded by 34 mukim or survey districts in the outer regions.
