Dium or Dion ( or ÃÂïÃÂý or ÃÂïÿý) was a town in the northwest of ancient Euboea near the promontory Cenaeum, from which Canae in Aeolis is said to have been a colony. Dium is mentioned by Homer, as under the leadership of Elephenor, in the Catalogue of Ships in the Iliad.
Dium is tentatively identified with the site of Likhas Kastri.
