Balša Stracimirović (last name is sometimes Balšić or Đurđević; Serbian: Балша III Страцимировић Балшић) or Balša III was the fifth and last ruler of Zeta from the Balšić noble family, from April 1403 to April 1421. He was the son of Đurađ II and Jelena Lazarević.
Balša had waged a new war against Venice, which was connected to the war with the Hungarians and the Turks. In 1418, he conquered Shkodër from the Venetians, but lost Budva and Luštica with its salt works. In the next year, 1419, he made an unsuccessful attempt to recapture Budva. He went to Belgrade to ask for aid from Stefan Lazarević, but never returned to Zeta. In 1421, before his death and under the influence of his mother, he passed the rule of Zeta to his uncle, Despot Stefan Lazarević.
