Lucius Junius Caesennius Paetus (c. 45 - after 94) was a Roman senator active during the Flavian dynasty.
He was suffect consul for the nundinium of March-June 79 with Publius Calvisius Ruso as his colleague.
[1] Caesennius was the son and namesake of Lucius Caesennius Paetus, consul in 61, and Flavia Sabina, the daughter of Titus Flavius Sabinus.
[2] Paetus is known to have served as a military tribune in 62 under Domitius Corbulo.
[3] Despite the military reverses of his father, his career was not unduly harmed, for Paetus was Consul Suffectus and finally proconsular governor of Asia in 93/94.
