Pratt & Whitney is an American owned aircraft engine manufacturer whose products are widely used in both civil and military aircraft. The company was founded in 1860 by Francis Pratt & Amos Whitney with headquarters in East Hartford, Connecticut.

As one of the "big three" aero-engine manufacturers the company competes with General Electric and Rolls-Royce. In addition to aircraft engines, Pratt & Whitney manufactures fixed gas turbines for industry and power generation, marine turbines, and railway locomotive engines.

Pratt & Whitney is a business unit of industrial conglomerate United Technologies, making it a sister company to Pratt & Whitney Canada (PWC), Otis Elevator Company and refrigeration giant Carrier Corporation. PWC designs and builds the smaller aircraft engines while P&W manufactures the larger engines.
