The de Havilland Gipsy Major is a four cylinder, air-cooled, inline engine used in a variety of light aircraft produced in the 1930s (including the Tiger Moth biplane), 1940s and 1950s, plus the Saro Skeeter helicopter. Engines were produced by de Havilland in the UK and Australia, the latter modifying the design to imperial measures instead of the original metric measurements.  First built in 1932, 14,615 Gipsy Majors were produced and many still power vintage aircraft worldwide today.

First built in 1932, total production of all Gipsy Major versions was 14,615 units.

In Canada the Gipsy Major was the engine of choice for the DHC1 Chipmunk trainer, which later replaced the Tiger Moth in the RAF. By 1945 the Gipsy Major had been cleared for a world record 1,500 hours time surpassing its previously held world record of 1,260 hours in 1943.
