Armeekorps) was a corps-level command of the German Army on the Western Front during World War II.

It was created on 24 September 1942, in Military Region (Wehrkreis) VIII as the LXIV Reserve Corps with the mission of supervising reserve divisions assigned to OB West, the German high command in the west.

By September 1944, LXIV Corps had established a line of defense in the Vosges Mountains as part of the German Nineteenth Army.

Attempts by the corps to reunite its elements failed in the face of Allied strength, and the commander of the corps at that time, General der Artillerie Max Grimmeiss,[4] was found sheltering at a hospital in Konstanz and taken prisoner by the French army on April 26.

[5][6] Remnants of the LXIV Corps fought alongside other equally tattered remnants of the Nineteenth Army in late April and early May until the unconditional surrender of Germany ended the war in Europe.
