The Israel Aircraft Industries (IAI) Westwind is a business jet that became a cornerstone of the Israeli aircraft manufacturing industry and remained in production for twenty years. Usually set up for seven passengers, it can carry as many as ten, or be quickly reconfigured as a fast air freight aircraft.

The Westwind was originally designed in the United States by Aero Commander as a development of its twin-propeller namesake aircraft, first flying on 2 January 1963 as the Aero Commander 1121 Jet Commander. It was of broadly conventional business jet arrangement, with two engines mounted in nacelles carried on the rear fuselage. However the wings were mounted halfway up the fuselage instead of the typical low-wing arrangement of aircraft in this class. After successful testing, the aircraft was put into series production with deliveries to customers beginning in early 1965.
