The Northern Ireland Security Guard Service (NISGS) is a civilian organisation of the Ministry of Defence that provides armed security at military establishments in Northern Ireland.

It was founded in 1998 following the Good Friday Agreement and is a unionised, non-industrial civilian security guard organisation under the authority of the General Officer Commanding (Northern Ireland), who holds ultimate responsibility for the operation of the organisation. The NISGS works alongside the unarmed Ministry of Defence Guard Service (MGS).

In the rest of the United Kingdom, armed security is the responsibility of the Military Provost Guard Service, made up of service personnel.
