The Pratt & Whitney Canada PW100 engine family is a series of 2,000 to 5,000 horsepower (1,500 to 3,700 kW) turboprops manufactured by Pratt and Whitney's Canadian subsidiary, headquartered in Longueuil, Quebec.

Pratt & Whitney Canada have adopted a relatively unusual engine configuration for the PW100: a three shaft arrangement. Other engines with this basic configuration include the Rolls-Royce Gem and the EPI TP400-D6. In the PW100, a centrifugal LP compressor(except for the PW150 which uses a 3 stage axial LP compressor), driven by a single stage LP turbine, supercharges a centrifugal HP compressor, driven by a single stage HP turbine. Power is delivered to the offset propeller reduction gearbox via a third shaft, connected to a 2-stage free (power) turbine.

The engine first entered service in 1984.
