Sclerias the Tragedian was a 4th-century BCE dramatist. No biographical details for him survive, and his name does not appear in major reference works such as the Oxford Research Encyclopedia of Classics, Smith's Dictionary, or the Encyclopædia Britannica.
He is associated with a single, untitled work. No extant text or specific citation is recorded, indicating the work is lost and known only by name or from fragmentary transmission.
His absence from standard biographical dictionaries suggests Sclerias was a minor or obscure figure in Greek tragedy, possibly recorded only in a lost ancient list of dramatists. His literary influence cannot be determined.
