The Slavonian Military Frontier (Croatian: Slavonska vojna krajina or Slavonska vojna granica; German: Slawonische Militärgrenze; Serbian: Славонска војна крајина; Hungarian: Szlavón határőrvidék) was a district of the Military Frontier, a territory in the Habsburg monarchy, first during the period of the Austrian Empire and then during the Austro-Hungarian Monarchy.

Other important towns in the area included Sremski Karlovci, Stara Pazova, Zemun, and Sremska Mitrovica.

After the Treaty of Karlowitz (1699), Habsburg monarchy expanded its territory towards east and new sections of the Military Frontier were founded along the Sava, Danube, Tisa and Mureş rivers.

In 1783 it was placed under the unified control of the Croatian General Command (German: Kroatisches General-Commando) headquartered in Zagreb.

[1] The only changes of this province's borders and neighborhood before its integration into Kingdom of Croatia-Slavonia in 1881 were in 1848–1849 when autonomous Serbian Vojvodina included eastern parts of Slavonian Military Frontier and between 1849 and 1860, during the existence of Voivodeship of Serbia and Banat of Temeschwar, a separate Habsburg crownland which became a north-eastern neighbor of Slavonian Military Frontier.
