The Häfeli DH-2 was a 1910s Swiss two-seat reconnaissance aircraft, built by aircraft department of the Eidgenoessische Konstruktionswerkstaette (K + W) at Thun, Switzerland.

It was a two-bay of wood and fabric construction, powered by a 100 hp (75 kW) Mercedes D.I engine, the next five were fitted with an Argus As II water-cooled inline engine.

The engine required a large flat radiator which was mounted beside the front cockpit.

The six DH-2s built during 1916 were used to train pilots and observers until they were withdrawn from service in 1922.
