Gaius Antistius Vetus was a Roman politician and general who was consul suffectus in 30 BC as the colleague of Augustus, succeeding Marcus Licinius Crassus.
He was probably the son of Gaius Antistius Vetus, praetor in 70, and governor in 69 BC in Hispania Ulterior,[2] under whom Julius Caesar served as quaestor.
[4][5] He was forced to fight against Quintus Caecilius Bassus, the former governor and an opponent of Caesar, who refused to relinquish his post.
[11] In 35 BC, Vetus was given command of the ongoing war against the Salassi, perhaps as the governor of Transalpine Gaul,[12] which he prosecuted with vigour, but without success.
[14] Vetus was then made legate of Hispania Citerior in 26 BC, one of the few men of consular standing to be given a military province during the reign of Augustus.
