Asterius campaign in Gallaecia was a military campaign of the Roman army in the province of Gallaecia (northwestern Spain). In 420 there were two conflicts in which the Romans intervened: an uprising by Maximus and a war between Suebi against the Vandals and Alans. The command of the Roman army was in the hands of Asterius, the comes Hispaniae, who was supported by auxiliary forces of the governor of Diocese of Hispania Maurocellus.
