Lucius Calpurnius Piso Caesoninus (101 BC – c. 43 BC) was a Roman senator and the father-in-law of Julius Caesar through his daughter Calpurnia. He was reportedly a follower of a school of Epicureanism that had been modified to befit politicians, as Epicureanism itself favoured withdrawal from politics. Piso was consul in the year 58 BC with Aulus Gabinius as his colleague.
