Gaius Cocceius Balbus (fl. 1st century BC) was a Roman politician and military commander who served as suffect consul in 39 BC.
Biography A member of the Plebeian gens Cocceia, Cocceius Balbus was a supporter of Marcus Antonius.Syme, pg. 200 He was probably elected as praetor in 42 BC.Broughton, pg. 359 In 39 BC, he was appointed suffect consul to replace Lucius Marcius Censorinus.Broughton, pg. 386 In the same year, he was already identified as a legate to Marcus Antonius.
In around 35 BC, Cocceius Balbus served as either proconsular governor of Macedonia, or as a Legatus in Greece.Broughton, pg. 407 If he was the governor, he would have been the replacement of Gaius Asinius Pollio and would have supervised the Roman troops deployed against Parthini and Dardanii, the tribes that threatened Macedonia. During his time in Greece, he was acclaimed as Imperator by his troops.Syme, pg. 267 This was possibly during his campaign against the Dardanians. He eventually abandoned Marcus Antonius and threw his support behind Octavian after Antonius divorced Octavia the Younger.Stern, Gaius, Women, Children, and Senators on the Ara Pacis Augustae: A Study of Augustus' Vision of a New World Order in 13 BC (2006), pg. 351
Balbus and his brother, M. Cocceius Nerva, was elevated to patrician status by Actium Augustus and were both admitted to cohors primae admissionis. Nerva served Augustus in his negotiations with Marcus Antonius.
