The Hillcrest Bar bombing, also known as the "Saint Patrick's Day bombing", took place on 17 March 1976 in Dungannon, County Tyrone, Northern Ireland. The Ulster Volunteer Force (UVF), a loyalist paramilitary group, detonated a car bomb outside a pub crowded with people celebrating Saint Patrick's Day. Four Catholic civilians were killed by the blast—including two 13-year-old boys standing outside—and almost 50 people were injured, some severely.
