The Manx Air Derby was an air race held on the Isle of Man, with sporadic races from 1924 and the first official Derby run in 1936 over a 156-mile course on Whit Monday, notably featuring accomplished aviator Alex Henshaw. The event continued until the Second World War halted it, resumed in 1947, and was revived again in 1965 at Jurby Aerodrome, later run alongside the Tynwald Air Races.
