Gaius Calvisius Sabinus was a Roman Senator, who was consul in AD 26 as the colleague of Gnaeus Cornelius Lentulus Gaetulicus.
On the Kalends of July, the consuls were replaced by Quintus Junius Blaesus and Lucius Antistius Vetus.
One of the informers, a tribune of a city cohort by the name of Celsus, gave testimony that exculpated Calvisius and Appius Junius Silanus, consul in AD 28.
The emperor recalled the governor in AD 39, suspecting Calvisius and his wife of plotting against him, and brought charges against both.
Cornelia was accused of entering the camp at night dressed as a soldier, interfering with the guard, and committing adultery in the general's headquarters.
