The de Havilland C.24 was a two-seat autogyro built by de Havilland at its Stag Lane works in England in 1931 The C.24 was built in 1931 using a Cierva rotor head coupled to the cabin of a de Havilland DH.80A Puss Moth, and driven by a 120 hp Gipsy III engine.

[2] A single example (G-ABLM) was produced and is part of the Science Museum collection.

In 1932, it was redesignated C.26 (not to be confused with the unbuilt C.26 twin-engine autogiro design) when a two-blade rotor system was installed.

[3] Since 2008 it has been on loan to the de Havilland Aircraft Museum at Salisbury Hall, near London Colney in Hertfordshire.

In flight, it had a maximum speed of about 115 mph (185 km/h; 100 kn).
