Haliartus or Haliartos (Ancient Greek: Ἁλίαρτος), also known as Ariartus, Ariartos, Hariartus, or Hariartos (Ἀρίαρτος or Ἁρίαρτος), was a town of ancient Boeotia, and one of the cities of the Boeotian League. It was situated on the southern side of Lake Copais in a pass between the mountain and the lake. It is mentioned in the Catalogue of Ships in the Iliad by Homer, who gives it the epithet ποιήεις (grassy) in consequence of its well-watered meadows.
