Clitonymus the Historian (Κλειτώνυμος ὁ ἱστορικός) was a minor Greek historian of the 4th century BCE. No details of his life or origin survive. He is known only from a single citation in Plutarch, which identifies him as the author of a work on Syracuse [1].

His lost work, the Syracusan History or On Syracuse (Περὶ Συρακουσῶν), is preserved solely as a title. Plutarch references it as a source for the anecdote of Damon and Phintias, reporting that the tyrant Dionysius I was so impressed by their friendship that he asked to join their bond [1][2].

Clitonymus’s significance is minimal and derivative, existing only because Plutarch cited him. His work appears to have been a local history of Syracuse containing anecdotal material. The absence of other citations suggests his history was not widely circulated or influential in antiquity.
