The Armstrong Siddeley Tiger was a British 14-cylinder air-cooled aircraft radial engine developed by Armstrong Siddeley in the 1930s from their Jaguar engine.

The engine was built in a number of different versions but performance and dimensions stayed relatively unchanged.

The Tiger VIII was the first British aircraft engine to use a two-speed supercharger.
