Karl-Heinz Kempf (2 February 1920 – 3 September 1944) was a German Luftwaffe fighter ace and recipient of the Knight's Cross of the Iron Cross during World War II. The Knight's Cross of the Iron Cross was awarded to recognise extreme battlefield bravery or successful military leadership.
Serving with JG 21 (later JG 54) Gefreiter Kempf gained his first two victories during the Battle of France when he shot down a Hurricane on 12 May 1940, and on 26 May a French Morane. In the Battle of Britain he achieved three additional kills, two Hurricanes and one Spitfire.
During the fighting on the Eastern Front, Kempf gradually accumulated a further 48 victories. He was awarded the Ritterkreuz des Eisernen Kreuzes as an Oberfeldwebel with 7./JG 54 in February 1942. After returning to the Western Front, with JG 26 from August 1943 to September 1944 Kempf claimed twelve kills, including four four-engined bombers and three P-47 fighters.
He was shot down and wounded on 22 December 1943 and on recovery was posted to 9./JG 26 with which he claimed five victories over the Invasion Front in June and July 1944.
Karl-Heinz Kempf was credited with 65 kills in 445 missions, 48 of them over the Eastern Front.
