In Greek mythology, Meriones (Greek: Μηριόνης) was a son of Molus and Melphis or Euippe. Molus was a half-brother of Idomeneus. Like other heroes of mythology, Meriones was said to be a descendant of gods. As a grandson of (son of Minos), Meriones's ancestors include Zeus, Europa, Helios, and Circe. Meriones possessed the helmet of Amyntor, which Autolycus had stolen. He inherited the helmet from his father Molus and later gave it to Odysseus. Meriones killed seven men at Troy.
Hyginus lists Meriones as one of the suitors of Helen. This would have made him oath bound to participate in the Trojan War. Other ancient authorities, however, do not include him in the list. Among these are the Bibliotheca and Hesiod.
Though not usually numbered among the major characters, Meriones is a prominent character in Homer's Iliad. Meriones is mentioned in Books II, IV, V, VII, VIII, IX, X, XIII, XIV, XV, XVI, XVII. He is recorded to have killed Phereclus the son of Tecton (Book V), Adamas the son of Asius (Book XIII), Harpalion son of King Pylaemenes (Book XIII), Morys (Book XIV), Hippotion (Book XIV), Acamas (Book XVI), Laogonus son of Onetor (Book XVI), and wounded Deiphobus son of Priam (Book XIII).
