Hecato or Hecaton of Rhodes (; ) was a Greek Stoic philosopher.
He was a native of Rhodes, and a disciple of Panaetius, but nothing else is known of his life. It is clear that he was eminent amongst the Stoics of the period. He was a voluminous writer, but nothing remains. Diogenes Laërtius mentions six treatises written by Hecato:
- Περὶ ἀγαθῶν – On Goods, in at least nineteen books.
- Περὶ ἀρετῶν – On Virtues.
- Περὶ παθῶν – On Passions.
- Περὶ τελῶν – On Ends.
- Περὶ παραδόξων – On Paradoxes, in at least thirteen books.
- Χρεῖαι – Maxims.
In addition Cicero writes that Hecato wrote a work on On Duties, () dedicated to Quintus Tubero.
