The Armstrong Siddeley Serval was a British ten-cylinder aero engine developed by Armstrong Siddeley in the late 1920s. Following the company tradition the engine was named after the Serval wild cat.

The Serval was a ten-cylinder, double-row, air-cooled radial piston engine. It was developed from the Armstrong Siddeley Mongoose and was, more or less, two Mongooses built around a single crankcase. In fact, it first appeared as the Double Mongoose in May 1928.

Built in several variants, power output was about 340 hp (254 kW).
