41 Commando or No. 41 (Royal Marine) Commando was a unit of the Royal Marines trained as Commandos during the Second World War. They were part of the all Royal Marine 4th Special Service Brigade that took part in the Normandy landings in June 1944 and later that served in World War II, the Korean War, and in Northern Ireland.

41 Commando is particularly notable for having fought beside the American 1st Marine Division at the Battle of Chosin Reservoir during the Korean War, for which 41 Commando received the Presidential Unit Citation, the highest U.S. award presented to a military unit, in 1957. 41 Commando was disbanded and reformed several times during its history, the last being in 1981.
