The Rolls-Royce Griffon was a liquid-cooled inline vee aircraft engine with twelve cylinders. It was originally intended to be a scaled-up Merlin for use in naval torpedo bombers. It had 6" (15.2cm) cylinders and a 6.6" (16.8cm) stroke for a displacement of 2239 cubic inches (36.69 liters) and was a good engine, but never achieved the same power per unit weight as the ever-improving Merlin.

Aircraft using this engine included the Firefly and later versions of the Spitfire.
