Flavius Anicius Auchenius Bassus (fl. 425–435) was a high official of the Western Roman Empire. He was appointed as consul by the Western court with Antiochus Chuzon as a colleague. In 435 he held for the second time the office of praetorian prefect of Italy.
Bassus belonged to the noble gens Anicia; his father was the Anicius Auchenius Bassus who was consul in 408.
In 425 he held the rank of comes rerum privatarum at the Western court;[1] the following year was praetorian prefect, perhaps of Italy.[2]
He made accusations against Pope Sixtus III; when Emperor Valentinian III learned of these accusations, he ordered a synod to be convoked, at which the accusations were investigated and the Pope cleared by 56 bishops.[3]
