The British Free Corps was a unit of the Waffen-SS of Nazi Germany during World War II, made up of British and Dominion prisoners of war who had been recruited by Germany. The unit was originally known as the Legion of St George. Research by British historian Adrian Weale has identified 54 men who belonged to this unit at one time or another, some for only a few days. At no time did it reach more than 27 men in strength.

John Amery was a British fascist and Nazi collaborator during World War II. He was the originator of the British Free Corps, a volunteer Waffen-SS unit composed of former British and Dominion prisoners of war.
