Andronikos III Palaiologos (Greek: Ανδρόνικος Γʹ Παλαιολόγος), commonly Latinized as Andronicus III Palaeologus, was Byzantine emperor from 1328 to 1341. Born Andronikos Doukas Angelos Komnenos Palaiologos (Greek: Ἀνδρόνικος Δούκας Ἄγγελος Κομνηνός Παλαιολόγος), he was the son of Michael IX Palaiologos and Rita of Armenia. He was proclaimed co-emperor in his youth, before 1313, and in April 1321 he rebelled in opposition to his grandfather, Andronikos II Palaiologos. He was formally crowned co-emperor on February 1325, before ousting his grandfather outright and becoming sole emperor on 24 May 1328.

His reign included the last failed attempts to hold back the Ottoman Turks in Bithynia and the defeat at Rusokastro against the Bulgarians, but also the successful recovery of Chios, Lesbos, Phocaea, Thessaly, and Epirus. His early death left a power vacuum that resulted in the disastrous civil war between his Empress-dowager, Anna of Savoy, and his closest friend and supporter, John VI Kantakouzenos.
