Lucius Caesennius Antoninus (c. 95 – after 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.
