Carlo III Tocco (1464–1518) was the titular despot of Epirus and count palatine of Cephalonia and Zakynthos from the death of his father Leonardo III Tocco c. 1503 to his own death in 1518. Carlo lived in Rome, where he received pensions from both the Papacy and the Kingdom of Naples. As an adult, Carlo worked as a military officer, serving both the Papacy and Emperor Maximilian I.
Carlo was deeply bitter about the loss of his family's lands in Greece. He married Andronica Arianiti, daughter of Constantine Arianiti, another claimant to lands in Greece, and presented himself not only as the head of the former Epirote despotic family, but also as the heir of the Serbian Branković dynasty and the Byzantine imperial Palaiologos dynasty (though no titles were claimed).
