The gens Gavia, or occasionally Gabia, was a Roman family of plebeian descent. It first appears in history during the first century BC, but none of its members obtained any of the curule magistracies until imperial times. The Gavi Arch at Verona was built in honor of one of the Gavii.
As a nomen, Gavius is a patronymic surname, derived from the praenomen Gavius. In historical times, this praenomen was used by the Oscan-speaking peoples of central and southern Italy, suggesting that the Gavii were originally of Sabine or Samnite origin; one of the most famous persons with this praenomen was Gavius Pontius, a Samnite general during the Second Samnite War.
But as with other patronymic surnames, there may originally have been several unrelated families bearing the same nomen, and some of these could also have been of Latin origin; Gavius is thought to be the original form of Gaius, one of the most common praenomina in every period of Roman history. That name is derived from an ancient root meaning "to rejoice". As it is impossible to distinguish between different families of Gavii with absolute certainty, all persons bearing this nomen are collected here.
Publius Gavius, an inhabitant of Cosa, whom Verres had crucified.
Titus Gavius Caepio, described by Cicero as a wealthy aristocrat. During the Civil War, his son was a military tribune under Marcus Calpurnius Bibulus in Syria.
Lucius Gavius, an agent of Marcus Junius Brutus in Cappadocia when Cicero was proconsul of Cilicia, from 51 to 50 BC. At Brutus' request, Cicero offered Gavius a prefecture, but found him very disrespectful, and referred to him as Publius Clodius' dog. He may be the same person as the Gavius of Firmum previously mentioned by Cicero.

Gavius or Gabius Bassus, a grammarian, whose Commentarii and Origine Verborum et Vocabulorum were cited by Aulus Gellius. He is probably the same Gavius who was the author of De Diis, discussed by Macrobius, and may have authored the Satirae quoted by Fabius Planciades Fulgentius.
Gavius Bassus, prefect of the Pontic coast during the reign of Trajan. Although sometimes identified with the grammarian, he is unlikely to have been the same person, as the grammarian related having seen the horse Sejanus, which had belonged to Publius Cornelius Dolabella, Gaius Cassius Longinus, and Marcus Antonius, a century and a half earlier.
