The House of Balšić (Serbian Cyrillic: Балшићи; Albanian: Balsha, Balshaj), or Balsha, were a noble family that ruled "Zeta and the coastlands" (current-day southern Montenegro and northern Albania), from 1362 to 1421, during and after the fall of the Serbian Empire. Balša, the founder, was a petty nobleman who held only one village during the rule of Emperor Dušan the Mighty (r. 1331–1355), and only after the death of the emperor, his three sons gained power in Lower Zeta after acquiring the lands of gospodin Žarko (fl. 1336–1360) under unclear circumstances, and they then expanded into Upper Zeta by murdering voivode and čelnik Đuraš Ilijić (r. 1326–1362†). Nevertheless, they were acknowledged as oblastni gospodari of Zeta in edicts of Emperor Uroš the Weak (r. 1355–1371). After the death of Uroš (1371), the family feuded with the Mrnjavčevići, who controlled Macedonia.
When the last lord of the main branch of the family, Balša III died in 1421 without an heir, his possessions were passed on to his uncle, Despot Stefan the Tall. Later that year, the Republic of Venice took advantage of Balša's death and seized the towns of Bar and Ulcinj, and some of his other territories were seized by the Ottomans and Bosnians.
