Vojinović (Serbian Cyrillic: Војиновић, Vojinovići / Војиновићи) was a medieval Serbian noble family which during the 14th century played an important role in the Serbian Empire, especially after the death of Emperor Dušan (King 1331–1346, emperor 1346–1355), when during the Fall of the Serbian Empire its representative Grand Dukes Vojislav Vojinović (around 1355–1363), and later his cousin Nikola Altomanović (1366–1373) were the strongest district masters in medieval Serbia.
