The Lycoming T53, (company designation LTC-1) is a turboshaft engine used on helicopters and (as a turboprop) fixed-wing aircraft since the 1950s.

It was designed at the Lycoming Turbine Engine Division in Stratford, Connecticut, by a team headed by Anselm Franz, who was the chief designer of the Junkers Jumo 004 during World War II.

A much larger engine, similar in overall design, became the Lycoming T55 produced by Honeywell Aerospace.

The T53 model is produced by Ozark Aeroworks LLC.
