Vuk Brankovic (Serbian Cyrillic: ??? ?????????, pronounced [?û?k bra?nko?it??], 1345 – 6 October 1397) was a Serbian medieval nobleman who, during the Fall of the Serbian Empire, inherited a province that extended over present-day southern and southwestern Serbia, the northern part of present day Macedonia, and northern Montenegro.
His fief (and later state) was known as Oblast Brankovica (District of Brankovic) or simply as Vukova zemlja (Vuk's land), which he held with the title of gospodin (lord, sir), under Prince Lazar of Serbia.
After the Battle of Kosovo (1389), Vuk was briefly the de facto most powerful Serbian lord.
