The Bristol Draco was an air-cooled nine-cylinder radial engine from the British manufacturer Bristol Aeroplane Company. It was essentially a version of their famous Pegasus converted to use a fuel injection system.

The carburettor had only a simple butterfly valve, while two injection pumps supplied the cylinders with fuel, one handling four cylinders and the other, five. Injection was into the manifold before they split into the two intake valves for each cylinder. The engine was flight-tested in a Westland Wapiti. Since the expenditure did not bring a considerable improvement, development was halted.
