The Tullyvallen massacre took place on 1 September 1975, when Irish republican gunmen attacked an Orange Order meeting hall at Tullyvallen, near Newtownhamilton in County Armagh, Northern Ireland. The Orange Order is an Ulster Protestant and unionist brotherhood. Five Orangemen were killed and seven wounded in the shooting. The "South Armagh Republican Action Force" claimed responsibility, saying it was retaliation for a string of attacks on Catholic civilians by Loyalists. It is believed members of the Provisional IRA carried out the attack, despite the organisation being on ceasefire.
