Stephanus or Stephen of Byzantium (Latin: Stephanus Byzantinus; Greek: Στέφανος Βυζάντιος, Stéphanos Byzántios; fl. 6th century AD) was a Byzantine grammarian and the author of an important geographical dictionary entitled Ethnica (Ἐθνικά). Only meagre fragments of the dictionary survive, but the epitome is extant, compiled by one Hermolaus, not otherwise identified.
