Gaius Asinius Pollio, son of Gaius Asinius Gallus and Vipsania Agrippina, was a Roman politician.
He was consul in AD 23 alongside Gaius Antistius Vetus. We know from his coins he was proconsul of Asia. Through his mother he was the half-brother of the younger Drusus. In 45, Pollio was exiled as an accuser of a conspiracy and later was put to death on orders from Empress Valeria Messalina.
The Asinia Pollionis filia mentioned on an inscription from Tusculum may have been his daughter. He was perhaps the father (or his brother) of Gaius Asinius Placentinus (b. 25), nob. v. at the middle of the 1st century, and (Marcus Asinius Pollio) (b. 30), the first of them perhaps the father of Marcus Asinius Pollio Verrucosus (45 or 50 – after 81), Consul in 81, the second of them perhaps the father of Marcus Asinius Atratinus (55 – after 89, Consul of Rome in 89, any of them in turn perhaps the father of Gaius Asinius M.f. Tucurianus, Proconsul in Sardinia ca 115 (Hypothesis 1). He was the older brother of Marcus Asinius Agrippa and Asinia, the mother of Pomponia Graecina.
