Pteleum or Pteleon (Ancient Greek: Πτελεόν), also Pteleos (Πτελεός), was a town of ancient Thessaly, on the south-western side of Phthiotis, and near the entrance of the Sinus Pagasaeus. It stood between Antron and Halos, and was distant from the latter 110 stadia, according to Artemidorus. It is mentioned by Homer in the Catalogue of Ships in the Iliad as governed by Protesilaus, to whom the neighbouring town of Antron also belonged.
