The gens Mettia, also written Metia, was a plebeian family at ancient Rome. Few members of this gens occur in history, and none attained the higher offices of the Roman state under the Republic. Several Mettii rose to prominence in imperial times, with at least three obtaining the consulship in the late first and early second century.^[1]

Origin

The Dictionary of Greek and Roman Biography and Mythology describes Mettius as "an old Italian name, in use both among the Sabines and Latins. It is doubtful whether Mettius or Metius is the better orthography, as we sometimes find one and sometimes the other in the best [manuscripts]."^[1] There is no reason to doubt that the nomen Mettius is a patronymic surname, based on the old praenomen Mettius, and perhaps sharing a common origin with the nomen of the Metilia gens.^[2]
