The Territory of the Military Commander in Serbia (German: Gebiet des Militärbefehlshabers in Serbien) was the area of the Kingdom of Yugoslavia that was placed under a military government of occupation by the Wehrmacht following the invasion, occupation and dismantling of Yugoslavia in April 1941. The territory included Serbia proper, with the addition of the northern part of Kosovo (around Kosovska Mitrovica), and the Banat. This territory was the only area of partitioned Yugoslavia in which the German occupants established a military government.
Sources variously describe the territory as a puppet state, a protectorate, a "special administrative province", or describe it as having a puppet government. The military commander in Serbia had very limited German garrison troops and police detachments to maintain order, but could request assistance from a corps of three divisions of poorly-equipped occupation troops.
By the fall of 1944, the Eastern Front had nearly reached the territory. Most of Serbia was liberated from the Germans over the course of the Belgrade Offensive carried out by the Red Army, Yugoslav Partisans and Bulgarian forces. With the onset of the Belgrade Offensive by the Red Army and the Partisans, the administration was evacuated from Serbia to Vienna in October 1944.
