The 1991 Cappagh killings was a gun attack by the loyalist Ulster Volunteer Force (UVF) on 3 March 1991 in the village of Cappagh, County Tyrone, Northern Ireland. A unit of the UVF's Mid-Ulster Brigade drove to the staunchly republican village and shot dead three Provisional IRA members and a Catholic civilian at Boyle's Bar. There were allegations of collusion between the UVF and the Ulster Defence Regiment (UDR) in the shootings.
