Giorgio de' Buondelmonti (Greek: Γεώργιος Μπουοντελμόντι, romanized: Geōrgios Bouontelmonti, c. 1403–after 1435) was the ruler of Ioannina for twenty days in 1411, under the regency of his mother Jevdokija Balšić.
After spending several years in exile, Giorgio reappears in the sources as the Byzantine court official George Izaoul (Greek: Γεώργιος 'ζαοúλ, romanized: Geōrgios Izaoul). Under this name, Giorgio married into the greater Byzantine imperial family and served as a companion of Demetrios Palaiologos, son of Emperor Manuel II Palaiologos. Giorgio remained involved in the affairs of the imperial family, as well as those of the Republic of Ragusa, until at least the 1430s.
