The Curtiss Model D is a single-engine two-seat utility biplane aircraft produced by the US-American manufacturer Curtiss Aeroplane Company. It is frequently named only the Curtiss Pusher because of the pusher configuration, where the propeller is behind the pilot.

The early models of the Model D were built in a canard configuration with additional elevators in front of the aircraft. The later models incorporated the elevators to the tailplane with the canard construction removed. They were called the ?Headless Pusher?. The Curtiss Pusher was the world?s first aircraft to takeoff from and to make the first landing aboard a ship.
