Paul Palaiologos Tagaris (Greek: Παῦλος Παλαιολόγος Τάγαρις, ca. 1320/40 – after 1394) was a Byzantine Greek monk and impostor. A scion of the Tagaris family, Paul also claimed a—somewhat dubious—connection with the Palaiologos dynasty that ruled the Byzantine Empire at the time. He fled his marriage as a teenager and became a monk, but soon his fraudulent practices embroiled him in scandal. Fleeing Constantinople, he travelled widely, from Palestine to Persia and Georgia and eventually, via Ukraine and Hungary to Italy, Latin Greece, Cyprus and France.
