The gens Plaetoria was a plebeian family at ancient Rome.
A number of Plaetorii appear in history during the first and second centuries BC, but none of this gens ever obtained the consulship.
Some scholars have suggested that the Plaetorii hailed from the ancient city of Tusculum in Latium.
[3][4] The main praenomina of the Plaetorii were Marcus, Gaius, and Lucius, the three most common names throughout Roman history.
[4] Their coins allude both to their name, depicting an athlete holding a cestus, and to a Praenestine origin, depicting Sors, the god of luck, associated with the renowned Praenestine oracle.
