Diphilus (Greek: Δίφιλος), of Sinope, was a poet of the new Attic comedy and a contemporary of Menander (342–291 BC). He is frequently listed together with Menander and Philemon, considered the three greatest poets of New Comedy. He was victorious at least three times at the Lenaia, placing him third before Philemon and Menander. Although most of his plays were written and acted in Athens, he died in Smyrna. His body was returned and buried in Athens.
