The gens Naevia, occasionally written Navia, was a plebeian or patrician family at ancient Rome. Members of this gens are first mentioned at the time of the Second Punic War, but the first of the Naevii to obtain the consulship was Lucius Naevius Surdinus, in AD 30.^[1]

The nomen Naevius is generally regarded as a patronymic surname derived from the praenomen Gnaeus, indicating a birthmark.^[2] Gnaeus and naevus, the usual form of the Latin word for a birthmark, were pronounced similarly, and a number of other Latin words could be spelled with either gn- or n-, such as gnatus and natus, "born".^[3]

In the time of the Republic, the principal cognomina of the Naevii were Balbus and Matho.^[1] Balbus, a common surname, originally signified one who stammers.^[4] Chase regarded Matho as a borrowing of the Greek Μαθων.^[5] Cicero stated that it was pronounced Mato, and sometimes spelled without an 'h'.^[6] Other Naevii bore the surnames Crista, Pollio, and Turpio, while Capella and Surdinus are found on coins.^[7][1] Crista refers to a crest or plume;^[8] Pollio is thought to mean "polisher", and to refer to the occupation of polishing arms.^[9][10] Turpio describes someone ugly, deformed, or foul.^[11] Capella refers to a she-goat, while Surdinus probably described someone who was deaf, hard of hearing, stubborn, or silent.^[12]

This list includes abbreviated praenomina. For an explanation of this practice, see filiation.
