South Serbia (Serbian: Јужна Србија / Južna Srbija) was a province (pokrajina) of the Kingdom of Serbs, Croats and Slovenes that existed between 1919 and 1922.

It encompassed the modern territories of Sandžak (parts of Serbia and Montenegro), Kosovo and North Macedonia.

[1] The province of South Serbia, as a mostly highland region, had favorable conditions for development of cattle breeding as illustrated by statistics on the increase of livestock numbers.

[2] The restoration of cattle breeding, which had been destroyed during the war years, was the primary goal of the Ministry of Economy.

[3] Following the First World War in Vardar Macedonia and the so called Western Outlands, the local Bulgarian population was not recognized as separate community and became a subject of state-policy of Serbianisation.
