The gens Arruntia was a plebeian family at ancient Rome. Members of this gens first came to prominence during the final years of the Republic. Origin The nomen Arruntius is a patronymic surname, based on the Etruscan praenomen Arruns, which must have been borne by the ancestor of the gens. Praenomina The chief praenomina of the Arruntii were Lucius and Marcus. Besides these, there are only a few examples of other names used by members of this gens, including Gaius and Quintus. Branches and cognomina The historian Ronald Syme identified three distinct families of the Arruntii: the first descended from the admiral Lucius Arruntius, and ended with Arruntius Camillus Scribonianus; another originated at Patavium; the third came from Lycia, whence they were descended from a certain Arruntius who settled in the east during the early years of the Roman Empire.

Lucius Arruntius L. f. L. n. Camillus Scribonianus, consul in AD 32, and afterward governor of Dalmatia.
