The Beechcraft 1900 is a 19-passenger, pressurized twin-engine turboprop airplane manufactured by the Beechcraft Division of the Raytheon Company (now Hawker Beechcraft). It was designed as and is primarily used as a regional airliner. It is also used as a freight aircraft, corporate transport, and by the United States military and other governments.

The aircraft is designed to carry passengers in all weather conditions from airports with relatively short runways. It is capable of flying well in excess of 600 miles, although few operators use its full fuel range. In terms of the number of aircraft built and its continued use by many passenger airlines and other users, it is the most popular 19-passenger airliner in history
