The Selton Hill Ambush took place on 11 March 1921, during the Irish War of Independence. An Irish Republican Army (IRA) flying column was ambushed by members of the RIC Auxiliary Division at Selton Hill (a.k.a. Seltan Hill), County Leitrim. Six IRA members of the South Leitrim Brigade were killed, which effectively destroyed the IRA in South Leitrim.
