Philonides was a Greek comic poet of the 4th century BCE, a native of Laodicea. Active in Athens, he was also an actor who performed in and produced plays for Aristophanes, specifically noted for The Frogs and The Kokalos. This indicates a close professional association with the renowned playwright.
Only fragments and titles of two of his own comedies survive. The known titles are Antyllos and Bacchae, each preserved in a brief mention by Athenaeus.
His primary significance lies in his attested connection to Aristophanes, providing a valuable data point for understanding theatrical production in late 5th and early 4th century Athens. As a poet of the generation following Old Comedy, his nearly lost work places him among the fragmentary authors of the transitional period toward Middle Comedy.
