Leutnant Karl Christ (born 15 June 1897, date of death unknown) was a World War I flying ace credited with five aerial victories.

Karl Christ was born on 15 June 1897 in Darmstadt, the Grand Duchy of Hesse, in the German Empire. In January 1915, he joined the Die Fliegertruppen des deutschen Kaiserreiches (the German flying service). He trained with Fliegerersatz-Abteilung (Replacement Detachment) 6 at Grosenheim.

He began service with Kampfgeschwader 6 (Tactical Bomber Wing 6). By 1916, he was serving in Kampfgeschwader 5, a tactical bomber wing subordinate to the German Supreme Command. During this period, Christ won both classes of the Iron Cross.

Christ was commissioned a Leutnant on 23 March 1917 while serving with another bombing wing under the German Supreme Command—Bombengeschwader 2. In November 1917, he left Bogohl 2; the following month he joined Jagdstaffel 28, a single-seat fighter squadron, for service through war's end. Between 14 May and 14 October 1918, he had five of his six victory claims confirmed, though details are lacking on the last pair.
