The Tourmakeady Ambush or Battle of Tourmakeady occurs on May 3, 1921, during the Irish War of Independence. The South Mayo Brigade of the Irish Republican Army (IRA), commanded by Commandant Tom Maguire ambushes a Royal Irish Constabulary (RIC)/Black and Tan re-supply patrol in the village of Tourmakeady, County Mayo, in the west of Ireland in order to destroy the patrol and to cause the closure of Derrypark RIC Barracks, seven miles to the south.

A car transporting police officers is leading the two-vehicle convoy. It is shot at as it travels out of the village, causing the Crossley Tender behind to stop close to the local hotel. RIC Constables Christopher O’Regan and William Power, Sergeant John Regan and Black and Tans Constable Hubert Oakes all die in the ambush. British forces are able to take refuge in the hotel, where they call for reinforcements.

Following the ambush, the Flying Column takes to the nearby Partry Mountains and are subsequently engaged by British troops from the Border Regiment. IRA Adjutant (South Mayo Brigade) Michael O’Brien sustains fatal injuries when he is shot while trying to assist the injured Brigade leader, Commandant Maguire. Another IRA Volunteer, Pádraig Feeney, is also killed that afternoon.

On May 3, 1921, in reprisal for the ambush, Crown forces burn several commercial establishments and homes in the area. Extensive searches and reprisals follow in the area over the next week.

Monuments commemorating Michael O’Brien and Pádraig Feeney have since been erected in County Mayo.
