The gens Ateia was a plebeian family at Rome.
The gens does not appear to have been particularly large or important, and is known from a small number of individuals, of whom the most illustrious was the jurist Gaius Ateius Capito, consul in AD 5.
[1] The only praenomina associated with the Ateii mentioned by Roman writers are Lucius, Gaius, and Marcus, the three most common names at all periods of Roman history.
