John Amery (14 March 1912 – 19 December 1945) 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.

Amery conducted recruitment efforts, and made propaganda broadcasts for Germany. He later gave direct support to Benito Mussolini. He was prosecuted by the British authorities and pleaded guilty to eight counts of high treason, for which he was sentenced to death, seven months after the war in Europe ended.
