The Rolls-Royce Eagle V12 was an aero engine developed during the First World War by Rolls-Royce that was used to power a number of military aircraft.

The design was a liquid cooled V12 engine with the cylinders inclined at 60 degrees and the valves driven by overhead camshafts. It first ran in 1915. Bore and stroke were 4.5 inches by 6.5 inches (115 x 165 mm) giving a 20 litre capacity. The whole engine weighed 408 kg (900 lb) producing 360 hp (268 kW) at 1800 rpm.

Production ran until 1928 by which point 4,681 had been built.

There is an example of this engine in the Science Museum, London.
