Euenus (or Evenus) of Paros, (Greek: Εὔηνος), was a 5th century BC philosopher and poet who was roughly contemporary with Socrates. Several fragments of his poetry exist in the Palatine Anthology and 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 it cited twice in: Artemidoros, Oneirocritica 1,15 = Plutarch, Moralia 497A De amore prolis 4: ή δέος ή λύπη παις πατρι πάντα χρόνον ("fear and pain a child means forever for his father").
