The son of an otherwise unknown Gaius Junius Silanus, it is speculated that Junius Silanus was related to Marcus Junius Silanus (perhaps his cousin).^[2] Elected consul in 17 BC alongside Gaius Furnius, it has been postulated that he may have been a proconsular governor of Asia around 24/23 BC, but this has been challenged as highly unlikely.^[3] He may have been the biological father of Quintus Caecilius Metellus Creticus Silanus.^[4] Nothing further is known about his career.
