Karl Maria Blasius Allmendinger (3 February 1891 – 2 October 1965) was a general in the Wehrmacht of Nazi Germany during World War II. He commanded the 5th Infantry Division, V Army Corps then 17th Army on the Eastern Front. He was a recipient of the Knight's Cross of the Iron Cross with Oak Leaves.^[1]

Allmendinger was appointed to command the 5th Infantry Division as a Generalmajor on 25 October 1940.^[2] His division was committed to the invasion of the Soviet Union in June 1941, and he was awarded the Knight's Cross of the Iron Cross on 17 July.^[3] He was promoted to Generalleutnant on 1 August 1942,^[2] and was awarded the Oak Leaves to his Knight's Cross on 13 December 1942.^[3] He was relieved of command of the division on 4 January 1943.^[2]

On 1 July 1943, he was recalled into active service and appointed commanding general of the V Army Corps which operated in the Crimea. Assigned to command the 17th Army in early May 1944, his mission was to evacuate Sevastopol and lead his units back to Romania across the Black Sea. Considerable losses in men and material were suffered.

On 25 July 1944, Allmendinger was again relieved from command and transferred to the Führerreserve, where he remained without further active assignment until the end of the war.

He was taken prisoner of war by U.S. forces on 16 May 1945 and was released on 22 December 1947.
