Operation Farrier was a raid by British Commandos during the Second World War on the Yugoslavian island of Mljet. The raid by the Long Range Desert Group, No. 2 Commando and No. 43 (Royal Marine) Commando, all under the command of the 2nd Special Service Brigade, started on 22 May 1943. It came about because a previously planned raid "Operation Foothound" on the Ugljan and Pasman islands had to be abandoned.
