Flavius Vivianus (floruit 459-463) was a politician of the Eastern Roman Empire.
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.
Vivianus was well known as a generous and able administrator.
