O-290
Type Piston aircraft engine
National origin United States
Manufacturer Lycoming Engines
First run 1939
Major applications Taylorcraft Auster IV
Taylorcraft Auster V
Ground Power Unit
Produced 1942–1975 out of production
Developed into Lycoming O-435

The Lycoming O-290 is a dual ignition, four-cylinder, air-cooled, horizontally opposed aircraft engine. It was first run in 1939, and entered production three years later.

A common variant of the type is the O-290-G, a single ignition model which was designed to drive a generator as part of a ground power unit.
