458–468) was a politician of the Western Roman Empire, Consul and twice Praetorian prefect of Italy.
Basilius belonged to the Italian nobility, and was member of the influential gens Caecinia.
[1] Emperor Libius Severus (461–465) honoured Basilius with the consulate of the year 463 (during which he was already Patricius), also naming him Praetorian prefect of Italy, a position Basilius held until 465.
Sidonius asked Basilius' help, as he needed to petition Emperor Anthemius on behalf of his people; Basilius suggested that he compose a panegyric in honour of the Emperor, in occasion of the beginning of Anthemius' consulate (January 1, 468).
After the declamation, Basilius interceded with Anthemius for Sidonius, and the Emperor made the Gallo-Roman poet a senator, a Patricius and Praefectus urbi.
