Flavius Antoninus Messala Vivianus^[1] (Greek: Βιβιανός; fl. 459–463) was an administrator of the Eastern Roman Empire.

Vivianus was the father of Paulus (Consul in 512) and Adamantius. His full nomenclature is found on a monument from an uncertain province, indicating that he held the ranks of vir illustris and patricius, and that he had been praetorian prefect and consul ordinarius.^[2]

He was praetorian prefect of the East between 459 and 460. In 463 he was appointed Consul by the Eastern court, but he was not recognised in the West, where the only consul was Caecina Decius Basilius.
