Theodore Palaiologos (Italian: Teodoro Paleologo, Greek: Θεόδωρος Παλαιολόγος, romanized: Theodōros Palaiologos; 1452–1532) was a 15th- and 16th-century Greek stratiote (light-armed mercenary cavalryman) and diplomat in the service of the Republic of Venice and one of the key early formative figures of the Greek community in Venice. He was not related to the Palaiologos dynasty of the Byzantine Empire, but his family may have been their distant cousins.
