Army Detachment Kempf was an army-sized formation of the Wehrmacht on the Eastern Front during World War II.

As part of Army Group South, Detachment Kempf saw action during Operation Citadel, the German attempt to cut off the Kursk salient and destroy a large part of the Soviet Army.

On 21 February 1943 Lanz was replaced by Werner Kempf and the detachment was renamed to reflect this change.

Beginning on the night of 4/5 July 1943, the III Panzer Corps, the detachment's primary attack formation, spearheaded the thrust east of Belgorod.

He was replaced by Otto Wöhler on August 16 and the detachment was designated as the 8th Army.
