Lucius Junius Caesennius Paetus (c. 20 - 72?) was a Roman senator, and member of the gens Caesennia and Junia, who held several offices in the emperor's service. He was consul ordinarius for the year 61 as the colleague of Publius Petronius Turpilianus.[1] Judith Ginsburg notes this made him the first novus homo to reach the ordinary consulship since Quintus Veranius 12 years before.[2]
