Oetylus or Oitylos (Ancient Greek: Οἴτυλος), also known as Beitylus or Beitylos (Βείτυλος), or Bityla (Βίτυλα), was a town of ancient Laconia on the eastern side of the Messenian Gulf, at the modern settlement of Oitylo. Pausanias says that it was 80 stadia from Thalamae and 150 from Messa; the latter distance is too great, but there is no doubt of the identity of Oetylus and modern Oitylo; and it appears that Pausanias made a mistake in the names, as the distance between Oetylus and Caenepolis is 150 stadia. Oetylus is mentioned by Homer in the Catalogue of Ships in the Iliad.
