A son of Hermes and Polymele, was brought up by his grandfather Phylas. He was one of the five leaders of the Myrmidones under Achilles, who sent him out to accompany Patroclus, and to prevent the latter from venturing too far; but Eudorus was slain by Pyraechmus. (Hom. Il. xvi. 179, &c.; Eustath. ad Hom. p. 1697.)
