The Ministry of Defence Brunei Darussalam (Malay: Kementerian Pertahanan), officially abbreviated as MinDef, is a cabinet-level ministry of the Government of Brunei. It is responsible for the national security and its military forces within the sultanate of Brunei Darussalam; the latter collectively known as the Royal Brunei Armed Forces (RBAF); Angkatan Bersenjata Diraja Brunei, (ABDB). MinDef is Brunei's ministry of defence; and was established on 1 January 1984 (1984-01-01), when Brunei Darussalam achieved independence from the United Kingdom. The Ministry of Defence leadership presently consists of a minister (First Minister); its incumbent is the Sultan of Brunei, Hassanal Bolkiah, who is also the Supreme Commander of the RBAF / ABDB. A deputy minister (Second Minister, officially styled Minister of Defence II) is second-in-command at the Ministry of Defence.

The Ministry of Defence is headquartered within Bolkiah Garrison in Bandar Seri Begawan, the capital of Brunei Darussalam, in the Brunei-Muara District, with the postcode BB3510.
