Bato was a Greek comic poet who lived during the 3rd century BCE, in the Hellenistic period. He is a minor figure known only from a single ancient source, the Byzantine encyclopedia called the Suda. No details about his life, origin, or social background have survived.

He wrote during the era of New Comedy, a style focused on domestic and romantic plots. According to the Suda, Bato was the author of two comedies: Sybarites and Tarentines. Both plays are now lost, and their content is unknown. Their titles suggest the comedies may have been set in or made use of stereotypes about the Greek colonies of Sybaris and Tarentum in southern Italy.

Bato’s significance lies in being one of many comic poets whose names were preserved in later scholarly works. He represents the broad and varied world of Hellenistic comedy beyond the few major authors whose complete works survive. The titles of his lost plays indicate that humor based on geographical or cultural stereotypes remained a feature of comedy in his time.
