In Greek mythology, Asius (Ancient Greek Ἄσιος) son of Hyrtacus is a Trojan ally from Arisbe by the river Selleïs. In the Iliad he leads the Hellespontine contingent, alone keeps his chariot when Hector assaults the Achaean wall, and falls to Idomeneus.

I.Iliadic ally
Homer (Iliad 2.835–840) makes Asius son of Hyrtacus, brought from Arisbe by the Selleïs with tawny tall horses; his mother Arisbe is Priam's first wife in later synchronisms. He commands towns on both shores of the Dardanelles. During the assault on the Achaean wall he alone ignores Hector and Polydamas and will not leave his chariot; Idomeneus of Crete kills him in that fight.
Virgil adds brothers Nisus and Hippocoon among Priam's allies. Keep him distinct from Asius son of Dymas (Hecuba's Phrygian brother) and from Asius companion of Aeneas in Italy.
II.Homonym care
The atlas id asius-hyrtacid is Hyrtacus' son alone — not asius (if ever entered) the Phrygian brother of Hecuba, nor Virgil's Italian Asius.
