The Piaggio P180 Avanti is an Italian executive transport aircraft with twin turboprop engines mounted in pusher configuration. It seats up to nine passengers in a pressurized cabin, and may be flown by one or two pilots. The design is of three-surface configuration, having both a small forward wing and a conventional tail plane as well as its main wing, with the wing spars passing outside of the passenger cabin area.

Design studies began in 1979 and designs were tested in wind tunnels in Italy and the United States in 1980 and 1981. A collaboration with Learjet to develop the aircraft began in 1983 but ended on 13 January 1986, with Piaggio continuing development on its own. The first prototype flew on 23 September 1986. American and Italian certification was obtained on 2 October 1990. Learjet's influence can be seen in the two "delta fins" mounted on the bottom of the tail, as found on most Learjets; these devices help provide yaw stability and pitch stability at high angles of attack.
