The gens Tarquinia was a plebeian family at ancient Rome, usually associated with Lucius Tarquinius Priscus and Lucius Tarquinius Superbus, the fifth and seventh Kings of Rome. Most of the Tarquinii who appear in history are connected in some way with this dynasty, but a few appear during the later Republic, and others from inscriptions, some dating as late as the fourth century AD.
