Klaus Mietusch (5 August 1918 – 17 September 1944) was a German Luftwaffe fighter pilot during World War II and a recipient of the Knight's Cross of the Iron Cross with Oak Leaves. Mietusch was credited by Nazi propaganda with 75 victories during his combat career. He was shot down by an American P-51 pilot in September 1944 and was posthumously awarded the Oak Leaves to his Knight's Cross on 18 November 1944. According to JG 26 historian Donald Caldwell, Mietusch was shot down nine previous times and was wounded at least four times. He had logged 452 combat sorties by the time of his death.
