Lucius Caesennius Antoninus (c. 95after 128) was a Roman aristocrat. He was suffect consul for the nundinium of February to March 128 with Marcus Annius Libo as his colleague.[1]
His ancestry is uncertain. Ronald Syme stated that it was possible he was the son of Lucius Caesennius Sospes, consul in 114, but in a footnote Syme admitted Antoninus could be the grandson of his brother Lucius Junius Caesennius Paetus, consul in 79.[2]
