Armeekorps) was an army corps of Germany's Wehrmacht during World War II.

The LXXXXI Army Corps was established using the staff of Oberfeldkommandantur 395, the former Befehlshaber Saloniki-Ägäis, on 7 August 1944.

It was initially deployed in occupied Greece and occupied Serbia under Army Group E (Löhr), which was in turn subordinate to Army Group F (von Weichs).

Between 6 and 21 March 1945, the Corps attacked the Soviets and Bulgarians in Southern Hungary from Yugoslavia in Operation Spring Awakening,[1] but was defeated in the Battle of the Transdanubian Hills.

In April 1945 the Corps moved to the Independent State of Croatia, before eventually surrendering in Styria in May 1945.
