The Rotax 503 is a 37 kW (50 hp), inline 2-cylinder, two-stroke aircraft engine, built by BRP-Rotax GmbH & Co. KG of Austria for use in ultralight aircraft.

For decades the engine was one of the most popular and reputedly reliable aircraft engines in its class (two-stroke, under 60 horsepower), and it remains widely used and supported.

As of 2011 the Rotax 503 is no longer in production. However, a Russian manufacturer has developed an approximate reproduction, the RMZ 500. Rotax subsequently offered only one other two-stroke engine for aircraft, the partially water-cooled Rotax 582.
