Cephisodorus (Ancient Greek: Κηφισόδωρος) was an Athenian dramatist of the Old Comedy. According to Lysias, he was a comic poet who won a victory in 402 BC. This victory was probably in the Lenaea; around the same time Cephisodorus appears on the surviving victory lists for the City Dionysia. The Suda says that he was a tragedian, and credits him with four plays: Antilais, Amazons, Trophonius, and The Hog. The titles quoted by the Suda are comic, and so the identification of Cephisodorus as a tragedian is likely to be an error.
