Phaedrus (/ˈfiːdrəs, ˈfɛdrəs/), son of Pythocles, of the Myrrhinus deme (Greek: Φαῖδρος Πυθοκλέους Μυῤῥινούσιος, Phaĩdros Puthokléous Murrhinoúsios; c. 444 – 393 BC), was an ancient Athenian aristocrat associated with the inner-circle of the philosopher Socrates. He was indicted in the profanation of the Eleusinian Mysteries in 415 during the Peloponnesian War, causing him to flee Athens.

He is best remembered for his depiction in the dialogues of Plato. His philosophically erotic role in his eponymous dialogue and the Symposium inspired later authors, from the ancient comedic playwright Alexis^[1] to contemporary philosophers like Robert M. Pirsig and Martha Nussbaum.^[2]
