UVF Mid-Ulster Brigade formed part of the loyalist paramilitary Ulster Volunteer Force in Northern Ireland. The brigade was established in Lurgan, County Armagh in 1972 by its first commander Billy Hanna. The unit operated mainly around the Lurgan and Portadown areas. Subsequent leaders of the brigade were Robin Jackson, known as "The Jackal", and Billy Wright. The Mid-Ulster Brigade carried out many attacks, mainly in Northern Ireland, especially in the South Armagh area, but it also extended its operational reach into the Republic of Ireland. Two of the most notorious attacks in the history of the Troubles were carried out by the Mid-Ulster Brigade: the 1974 Dublin and Monaghan bombings and the Miami Showband killings in 1975. Members of the Mid-Ulster Brigade were part of the Glenanne gang which the Pat Finucane Centre has since linked to at least 87 lethal attacks in the 1970s.

The Ulster Volunteer Force (UVF) is an Ulster loyalist paramilitary group based in Northern Ireland. Formed in 1965, it first emerged in 1966. Its first leader was Gusty Spence, a former Royal Ulster Rifles soldier from Northern Ireland. The group undertook an armed campaign of almost thirty years during The Troubles. It declared a ceasefire in 1994 and officially ended its campaign in 2007, although some of its members have continued to engage in violence and criminal activities. The group is a proscribed organisation and is on the terrorist organisation list of the United Kingdom.
