The Austin A.F.T.3 Osprey was a prototype British fighter triplane of the First World War.

In 1917, Britain's War Office issued Specification A.1.A for a single-seat fighter to replace the Sopwith Camel.

To meet this requirement, the Austin Motor Company, already a large scale manufacturer of aircraft to Royal Aircraft Factory designs, produced its own design for a single-engined triplane, the A.F.T.3 Osprey, receiving a licence to build three prototypes as a private venture.

[1] The Osprey was of conventional wood and fabric construction, with single-bay triplane wings.

When the Snipe was selected as the winner of the competition for the new fighter, Austin abandoned development of the Osprey, with the second and third prototypes not completed.
