HQ Northern Ireland was the formation responsible for the British Army in and around Northern Ireland. It was established in 1922 and disbanded, replaced by a brigade-level Army Reserve formation, 38 (Irish) Brigade, in 2009.

Northern Ireland District was established following the partition of Ireland in 1922 and was originally based at Victoria Barracks, Belfast. During the Second World War the role of the District was enhanced from internal security to that of combatting any threat of invasion from the Republic of Ireland. The status of the formation was upgraded from District to Command under the leadership of Lieutenant General Sir John Hackett in 1961.

With the emergence of the Troubles, which started in Northern Ireland in the late 1960s, the role of HQ Northern Ireland increased substantially as it took responsibility for "assisting in the defeat of terrorism and the maintenance of public order" and by 1972 it had 27,000 troops under its command.

On 30 January 2006 the Secretary of State for Defence announced to the House of Commons that 19 Light Brigade, then stationed at Catterick, would be re-roling into a light brigade and relocating to Scotland and Northern Ireland. On 10 May 2006 it was further announced that "in addition to the HQ and other units of 19 Light Brigade that we expect to relocate to Northern Ireland in 2007 and 2008, a new and non-deployable regional brigade headquarters will form at Thiepval Barracks, Lisburn. The current 107 (Ulster) Brigade, based at Ballymena, will merge on 15 December this year into HQ 39 Infantry Brigade, which will itself be replaced by the new regional brigade headquarters, 38th (Irish) Brigade under the command of the 2nd Division, on 1 August 2007".
