Otto Brauneck (27 February 1896 – 26 July 1917) was a German World War I flying ace credited with ten confirmed and five unconfirmed aerial victories.

Originally assigned to fly on the Macedonian Front to support Germany's ally, the Ottoman Empire, between September 1916 and April 1917 Brauneck shot down four enemy observation balloons and three aircraft, with a further five claims going unproven.

Transferred to the Red Baron's Jagdstaffel 11 in France, Brauneck scored a further three victories before being killed in action on 26 July 1917.

On 20 April 1917, he moved to Jasta 11 on the Western Front, to serve under Manfred von Richthofen.

On 22 July 1917, he shot down a 10 Naval Squadron Sopwith Triplane, probably Canadian seven-victory ace Flight Lieutenant John Albert Page.
