The Halberstadt C.I was a German single-engined reconnaissance biplane of World War I, built by Halberstädter Flugzeugwerke.
The Halberstadt C.I was designed in late 1916 as a reconnaissance derivative of the company's B.II equipped with an Oberusel U.1 rotary engine. The aircraft's armament consisted of two front 7.92-mm machine gun LMG 08/15 Spandau and one turret 7.92-mm machine gun Parabellum mounted in the rear cockpit on a mobile turret.
