Zenobius the Sophist was a Greek grammarian and teacher of rhetoric active in the 2nd century CE under the Roman Empire. A pupil of the rhetorician Timaeus the Sophist, he is also recorded in the Suda as having taught the emperor Hadrian, indicating his presence in high imperial circles. No further biographical details are extant.

His sole known work is a three-book collection titled Proverbs, which he dedicated to an otherwise unknown Agathopus. This compilation organized Greek proverbs alphabetically, often with brief explanations, and drew heavily from earlier collections by Didymus Chalcenterus and Lucillus of Tarrha. The original is lost, but a later epitome survives.

Zenobius’s significance lies in his role as a compiler. His collection became a foundational paremiographical text, preserving a vast array of Greek proverbs and popular wisdom. The alphabetic organization influenced later Byzantine scholars, and through the surviving epitome, Zenobius served as a crucial link between Hellenistic scholarship and later traditions.
