The Guinea Pig Club, established in 1941, was a social club and mutual support network for British and allied aircrew injured during World War II. Its membership was made up of patients of Archibald McIndoe at Queen Victoria Hospital, East Grinstead, Sussex, who had undergone experimental reconstructive plastic surgery, generally after receiving burns injuries in aircraft. The club remained active after the end of the war, and its annual reunion meetings continued until 2007.
