Gaius Norbanus Flaccus was a Roman politician and general during the 1st century BC.

Of Etruscan descent,Syme, pg. 200 Flaccus was the grandson of Gaius Norbanus. His family had suffered under the proscriptions of Lucius Cornelius Sulla, but had found favour under the regime of Julius Caesar.Syme, pg. 200 With Caesar's death, his allegiance passed to Octavianus, Caesar's adopted son.Syme, pg. 235

Norbanus was first elected as praetor in 43 BC.Broughton, pg. 337 With the establishment of the Second Triumvirate and the launching of the civil war against the Liberatores, in 42 BC Norbanus and another general, Decidius Saxa, were sent by Marcus Antonius and Octavianus with eight legions into Macedonia against the assassins of Julius Caesar.Holland, pg. 169 Ordered to march quickly to Thrace and hold the mountain passes, thus cutting off the Via Egnatia, Norbanus and Saxa met the combined advancing troops of Gaius Cassius Longinus and Marcus Junius Brutus in the neighborhood of Philippi.Syme, pg. 202 As they were outnumbered, Norbanus and Saxa occupied a position near Philippi which prevented the republicans advancing any further. Determined to find a way through, Brutus and Cassius managed to make Norbanus leave this dominating position, but Norbanus discovered the trap in time to recover it. When Brutus and Cassius managed to outflank them, Norbanus and Saxa retreated towards Amphipolis.Holland, pg. 170 When Marcus Antonius and the bulk of the triumvirs' troops arrived, they found Amphipolis well-guarded and Norbanus was left in command of the town. After the Battle of Philippi, Octavianus placed Norbanus in charge of his camp.Broughton, pg. 365

With the victory at Philippi, Norbanus enjoyed the prestige that came with being part of the successful campaign.Syme, pg. 235 In reward for his service, in 38 BC Octavianus nominated Norbanus as consul with Appius Claudius Pulcher.Syme, pg. 243 They were the first consuls to have two Quaestors each.Broughton, pg. 389 He then held the post of proconsul in Spain from 36 - 34 BC,Broughton, pg. 407; Syme, pg. 239 for which he celebrated a triumph on October 12, 34 BC.Broughton, pg. 411 This was then followed by an appointment as proconsul of Asia shortly after the Battle of Actium in 31 BC.Syme, pg. 303

Norbanus was married to a daughter of Lucius Cornelius Balbus the YoungerSyme, pg. 325 and had at least one son, also named Gaius Norbanus Flaccus.
