Gaius Aufidius Victorinus was a Roman senator and general of the second century.
[1] He was a student of Fronto at the same time as Marcus Aurelius, where their friendship began.
[2] In 155 Victorinus became suffect consul, then from c. 162 to c. 166 he was governor of Germania Superior, where he was commissioned to repulse the invading Chatti, which he did successfully.
[8] In the last year of his tenure as Urban prefect (probably from 179 to 183),[9] Victorinus was consul a second time with Commodus as his colleague.
At the death of Marcus Aurelius and the beginning of Commodus' tenure, Victorinus was still in high esteem, but Cassius Dio suggests that Commodus, probably at the instigation of the powerful Praetorian prefect Sextus Tigidius Perennis, sought to kill Victorinus.
