Belgrade Oblast () was one of the oblasts of the Kingdom of Serbs, Croats and Slovenes from 1922 to 1929. Its administrative center was Belgrade.
The Kingdom of Serbs, Croats and Slovenes was formed in 1918 and was initially divided into counties and districts (this division was inherited from previous state administrations). In 1922, new administrative units known as oblasts (Serbo-Croatian: oblasti / þñûðÃÂÃÂø) were introduced and the whole country was divided into 33 oblasts. Before 1922, the territory of the Belgrade Oblast was part of the Belgrade, Novi Sad, and Veliki BeÃÂkerek districts.
In 1924, as a result of an adjustment of the border between the Kingdom of Serbs, Croats and Slovenes and Romania, the town of à ½ombolj (Jimbolia) was transferred to Romania.
In 1929, 33 oblasts were administratively replaced with 9 banovinas and one district, and the territory of the Belgrade Oblast was administratively divided between the Belgrade City Administration and the Danube Banovina.
The Belgrade Oblast included a small northern part of à  umadija near Belgrade, western parts of Banat and eastern parts of BaÃÂka. It shared borders with the BaÃÂka Oblast and Syrmia Oblast in the west, the Valjevo Oblast in the southwest, the Podunavlje Oblast in the southeast, Romania in the northeast and Hungary in the north.
