Oreus or Oreos (), prior to the 5th century BC called Histiaea or Histiaia (Ἱστίαια), also Hestiaea or Hestiaia (Ἑστίαια), was a town near the north coast of ancient Euboea, situated upon the river Callas, at the foot of Mount Telethrium, and opposite Antron on the Thessalian coast. From this town the whole northern extremity of Euboea was named Histiaeotis (Ἱστιαιῶτις, ) According to some it was a colony from the Attic deme of Histiaea; according to others it was founded by the Thessalian Perrhaebi. Another foundation story had it that the name Histiaea is said to derive from the mythical figure Histiaea, the daughter of Hyrieus. It was one of the most ancient of the Euboean cities. It occurs in the Catalogue of Ships in the Iliad, where Homer gives it the epithet of πολυστάφυλος (rich in grapes); and the Periplus of Pseudo-Scylax mentions it as one of the four cities of Euboea. It was an important city in classical antiquity due to its strategic location at the entrance of the North Euboean Gulf, in the middle of a large and fertile plain.
