In Greek mythology, Agrius (Ancient Greek Ἄγριος, "wild") is one of the earthborn Giants. In Apollodorus' Gigantomachy the Moirai club him and Thoon to death with brazen maces while the Olympians and Heracles fight the rest of the brood.

I.Giant of the Gigantomachy
Apollodorus names Agrius among Gaia's giant sons who assault Olympus. While Zeus, Athena, and the other gods fight with Heracles' aid, the Fates kill Agrius and Thoon with clubs of bronze — a rare starring role for the Moirai in open battle.
The collective node gigantes holds the revolt and the disputed parentage of the brood; this node is the individual named in that roster.
