Marcus Junius D. f. M. n. Silanus was a Roman senator and consul in 25 BC as the colleague of Gaius Julius Caesar Octavianus, the emperor Augustus.
[2][3] Silanus was possibly the same man who served as one of Julius Caesar's legates in 53 BC.
The following year, Lepidus sent him with a detachment of troops to join Marcus Antonius at Mutina,[6] but refused to accept responsibility for the help which Silanus gave.
[9] A Silanus later served under Antonius in Achaea and Macedonia[10] from 34 to 32, with the title of Quaestor pro consule or perhaps Proquaestor.
[14] The future emperor raised him to the Patriciate in 30 BC,[15] and they held the consulship together in 25.
