The Twelve Caesars, is a set of twelve biographies of Julius Caesar and the first 11 emperors of the Roman Empire. The book discusses the significant and critical period of the Principate from the end of the Republic to the reign of Domitian. Packed with gossip, drama, and sometimes humour, The Twelve Caesars was considered very significant in antiquity and remains a primary source on Roman history.

Written in 121 AD during the reign of the emperor Hadrian, The Twelve Caesars was the most popular work of Suetonius, at that time Hadrian's personal secretary, and is the largest among his surviving writings. The book provides valuable information on the heritage, personal habits, physical appearance, lives, and political careers of the first Roman emperors, which include Julius Caesar, Augustus, Tiberius, Caligula, Claudius, Nero, Galba, Otho, Vitellius, Vespasian, Titus and Domitian. Also included are the lives of eminent grammarians, rhetoricians, and poets.
