Euenus (or Evenus) of Paros, (Greek: Εὔηνος), was a 5th-century BC philosopher and poet who was roughly contemporary with Socrates. Euenus is mentioned several times in Plato's Phaedo, Phaedrus (dialogue), and Apology of Socrates. He is quoted in the Nicomachean Ethics of Aristotle at 7.10.1152a32. He was apparently, although obscure, well respected, and was never called a Sophist by Socrates, even though he charged a sizeable sum for teaching students.
- One of his famous sayings is cited twice in: Artemidoros, Oneirocritica 1,15 = Plutarch, Moralia 497A De amore prolis 4: ἢ δέος ἢ λύπη παῖς πατρὶ πάντα χρόνον ("a son is always a terror or a pain for his father.").
- Montaigne quotes him to the effect that fire is the spice of life.
Eight poems are attributed to "Euenos" in the Palatine Anthology, but most are probably by Euenus of Ascalon, and some may be by Euenus of Athens, Euenus of Sicily or Euenus Grammaticus. Most are about works of art.
