Appius Junius Silanus, whom Cassius Dio calls Gaius Appius Silanus, was consul in AD 28, with Publius Silius Nerva as his colleague. He was accused of majestas, or treason, in AD 32 along with a number of senators, but he and Gaius Calvisius Sabinus were saved by one of the informers, Celsus, a tribune of a city cohort.
