Lucius Cispius, probably with the "cognomen" Laevus, was a commander of the fleet ("praefectus classis") in 46 BC, serving under Julius Caesar. He took part in the blockade of Thapsus. Cispius was not of senatorial rank, and has been tentatively linked to a pottery manufacturing family in Arretium. It is possible that he was the son of Marcus Cispius (above), though this filiation would place them on opposite sides in the civil war. In 43, a Cispius Laevus was a legate of Munatius Plancus, carrying dispatches to Rome for him; this man was most likely Caesar's naval commander.
