Sopater of Paphos was a Hellenistic comic poet active in the late 4th and early 3rd centuries BCE during the era of Alexander the Great’s successors. The Byzantine encyclopedia Suda identifies him as a writer of comedy from Paphos on Cyprus, distinguishing him from other poets of the same name. No further biographical details survive.

The Suda records a single comedy by Sopater, titled "The Gluttons" or "The Eaters," though it notes he wrote many works. The play is lost and survives only in fragments and by its title within standard collections of Greek comic fragments.

Sopater’s significance lies in exemplifying the spread of Attic-style comedy throughout the Hellenistic world following Alexander’s conquests. As a poet from Cyprus, he represents the cultural Hellenization of the eastern Mediterranean. The thematic suggestion of his known play aligns it with the domestic and character-driven plots of Middle or New Comedy.
