Epinicus was a comic poet who lived and worked in the 3rd century BCE, during the Hellenistic period. He is a minor figure known only from later historical records, with no details about his personal life or origins surviving. According to ancient sources, he wrote comedies, a popular form of drama in ancient Greece.

Only the titles of two of his plays have been preserved: Anteia and Pylaia. The plays themselves are lost, and no direct quotations from them exist. The date of his activity is uncertain, but modern scholars place him after the era of New Comedy, possibly within a later phase of Middle Comedy. The titles of his works follow the common naming patterns of the time, which often used women's names or place names.

Epinicus represents the many comic poets from this era whose works have not survived. His inclusion in a major Byzantine encyclopedia indicates he was remembered as part of the broader comic tradition, though his specific historical impact is not discernible. He is primarily noted in modern scholarship as an example of a poet known only by name and the titles of his lost works.
