The Kingdom of Serbia was a province (crownland) of the Habsburg monarchy from 1718 to 1739. It was formed from the territories to the south of the rivers Sava and Danube, corresponding to the Sanjak of Smederevo, conquered by the Habsburgs from the Ottoman Empire in 1717. It was abolished and returned to the Ottoman Empire in 1739.

The Sanjak of Smederevo, also known in historiography as the Pashalik of Belgrade, was an Ottoman administrative unit (sanjak), that existed between the 15th and the outset of the 19th centuries. It was located in the territory of present-day Central Serbia.
