Group Captain Claude Hilton Keith (21 October 1890 – 18 November 1946) was a British-Canadian aviator who was an early pioneer of air gunnery, playing a central role in the preparation of the Royal Air Force (RAF) for the Second World War. His work as Assistant Director of Armament Research and Development with responsibility for armament led to the establishment of the "Air Fighting Committee" in 1934. His career ended prematurely after championing the rights of RAF personnel posted in Canada.
