The following is an incomplete list of people from Allied countries suspected of treachery or treason during World War II. It is not a list of Nazi war criminals.
Treason is the crime of attacking a state authority to which one owes allegiance. This typically includes acts such as participating in a war against one's native country, attempting to overthrow its government, spying on its military, its diplomats, or its secret services for a hostile and foreign power, or attempting to kill its head of state. A person who commits treason is known in law as a traitor.
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.

At no time did it reach more than 27 men in strength.
