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.
