The gens Flavia was a plebeian family at ancient Rome. Its members are first mentioned during the last three centuries of the Republic. The first of the Flavii to achieve prominence was Marcus Flavius, tribune of the plebs in 327 and 323 BC; however, no Flavius attained the consulship until Gaius Flavius Fimbria in 104 BC. The gens became illustrious during the first century AD, when the family of the Flavii Sabini claimed the imperial dignity.^[1]

Under the Empire, the number of persons bearing this nomen becomes very large, perhaps due to the great number of freedmen under the Flavian dynasty of emperors. It was a common practice for freedmen to assume the nomina of their patrons, and so countless persons who obtained the Roman franchise under the Flavian emperors adopted the name Flavius, which was then handed down to their descendants. Freedmen under the Constantinian dynasty, whose members were also called Flavius, also adopted it, as did individuals who entered government service during their rule, often replacing their original nomina with the dynastic Flavius.^[1][2]

The vast majority of persons named Flavius during the later Empire could not have been descended from the Flavia gens; and indeed, the distinction between nomina and cognomina was all but lost, so that in many cases one cannot even determine with certainty whether it is a nomen or a cognomen. However, because it is impossible to determine which of these persons used Flavius as a gentile name, they have been listed below.^[1][3]

The Flavii of the Republic claimed Sabine ancestry, and may have been related to the Flavii who lived at Reate during the first century AD, from whom the emperor Vespasian descended; but the gentilicium is also found in other parts of Italy, such as Etruria and Lucania.^[1] The nomen Flavius is of Latin origin, and is derived from the surname Flavus, used by a number of gentes, and meaning "golden" or "golden-brown". It probably referred to the blond hair possessed by an early member of the family.^[4][5]

During the later period of the Empire, the name Flavius frequently descended from one emperor to another, beginning with Constantius Chlorus, the father of Constantine the Great.^[1][6] The name became so ubiquitous that it was sometimes treated as a praenomen, to the extent of being regularly abbreviated Fl., and it is even described as a praenomen in some sources, although it was never truly used as a personal name, and from the time of Honorius it appears chiefly in letters.^[6] It once again became a regular part of the nomenclature of the eastern emperors from Justinian I through the reign of Constantine IV, and appearing as late as the reign of Leo VI in the tenth century.^[1][7][8] After the name fell into disuse among the Byzantine emperors, it was used as a title of legitimacy among the barbarian rulers of former Roman provinces, such as Visigothic Spain and the kings of the Ostrogothic Kingdom of Italy and the Kingdom of the Lombards.^[9][10][3]

From the fourth century AD onwards, the name is widespread among non-emperors as a mark of dignity. It is widespread in epigraphy from Germania. In Egypt, where the evidence is best, it was part of the full name of all Imperial officials, all provincial officials, the highest civic officials, and most soldiers. This usage appears shortly after Constantine gained control of the province in 324 AD. Between 287 and 326 AD, Egyptians had used Valerius (the nomen of Constantine's predecessors) in a similar way. People not entitled to "Flavius" bore the nomen Aurelius or no nomen. Initially, people sometimes used the name Flavius alongside another nomen that they were entitled to (e.g. Julius, Aelius), but these other nomina died out over the fifth century.^[11] In the fourth century, the name was not inherited by children or wives of the "Flavius", but from the fifth century higher-ranking holders sometimes passed the name to their descendants.^[12] After the Arab conquest of Egypt in 646, the use of "Flavius" was less consistent and after some time it died out.^[13]

In modern use, Flavius is a personal name, and widely used in romance languages, including Italian and Spanish Flavio (fem. Flavia), French Flavien (fem. Flavie), Portuguese Flávio (fem. Flávia), and Romanian Flavius or Flaviu (fem. Flavia).

The early Flavii used the praenomina Marcus, Quintus, Gaius, and Lucius. Of these, only Gaius and Lucius are known from the family of the Fimbriae. The name Gnaeus occurs once, but as the son of a freedman of the family, and thus does not seem to be representative of the gens. The Flavii Sabini appear to have restricted themselves to the praenomen Titus alone, and distinguished their sons by the use of different surnames, usually by giving the younger sons surnames derived from their maternal ancestors.

The Flavii of the Republic used the cognomina Fimbria, Gallus, Lucanus, and Pusio.^[1] Only the Fimbriae, whose surname refers to a fringe or border, represented a distinct family.^[14][15] Gallus and Lucanus belong to a class of surnames derived from places of origin or association, referring to Gaul and Lucania, respectively, although Gallus, a very common surname, could also refer to a cockerel.^[16][17] Pusio was originally a nickname indicating a little boy, and would have been bestowed on someone small or youthful.^[18]

The Flavii Sabini, whose surname indicates Sabine ancestry, rose to prominence under the Empire. They were descended from Titus Flavius Petro, a soldier from Reate who fought under Gnaeus Pompeius Magnus. Within two generations they had attained such respectability that two of his grandsons held the consulship in consecutive years, AD 51 and 52; the younger of these marched to Rome at the head of an army in the year of the four emperors, AD 69, and claimed the imperial dignity as the emperor Vespasian. However, within less than thirty years, the family was largely destroyed through the workings of Vespasian's son, the emperor Domitian.^[19][16] The Flavii Titiani may be descended from the Flavii Sabini through the consul Titus Flavius Clemens, a nephew of Vespasian; the first of this branch, Titus Flavius Titianus, who was governor of Egypt from AD 126 to 133, may have been his son.

A family of the Flavii bearing the surname Valens lived at Hatria, and from there migrated to Rome in imperial times, where two of them served as prefects of different cohorts.^[20]

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

• Marcus Flavius, tribune of the plebs in BC 327 and 323.^[21][22]

• Quintus Flavius, an augur who, according to Valerius Maximus, was accused by the aedile Gaius Valerius (perhaps the same who was curule aedile in BC 199). When fourteen tribes had already voted against Flavius, who again asserted his innocence, Valerius declared that he did not care whether the man was guilty or innocent, provided he secured his punishment; and the people, indignant at such conduct, acquitted Flavius.^[26][27]
• Quintus Flavius, of Tarquinii, murdered the slave Panurgus, who belonged to Gaius Fannius Chaerea, and who was to be trained as an actor by Quintus Roscius, the celebrated comedian.^[28]
• Lucius Flavius, an eques, who gave evidence against Verres in BC 70. He probably lived in Sicily, and was engaged in mercantile pursuits. He appears to be the same Lucius Flavius who is mentioned as procurator (that is, the agent or steward) of Gaius Matrinius in Sicily.^[29]
• Gaius Flavius, brother of Lucius, and likewise an eques, whom Cicero recommended in BC 46 to Manius Acilius, praetor of Sicily, as an intimate friend of Cicero's late son-in-law, Gaius Calpurnius Piso Frugi.^[30]

• Lucius Flavius, praetor in BC 58, and a supporter of Pompeius. He was plebeian tribune in 60 BC and failed in passing a land reform programme for Pompey's veterans. He was also a friend of both Cicero and Caesar, and may have been the same Flavius whom Caesar entrusted with one legion and the province of Sicily in BC 49.^{[32][33][34][35]}
• Gaius Flavius, an eques of Asta, a Roman colony in Spain. He and other equites, who had belonged to the party of Pompeius, went over to Caesar in BC 45.

• Gaius Flavius C. f. C. n. Fimbria, a violent partisan of Gaius Marius, at whose funeral he tried to kill Quintus Mucius Scaevola, the Pontifex Maximus. Sent to Asia in an expedition against Mithridates and Sulla, Fimbria led a mutiny against the consul Valerius Flaccus, whom he murdered, taking command of the army. With much savagery, he subdued much of Asia, but when his men went over to Sulla, he took his own life.^[14][43]
• Flavius C. f. C. n. Fimbria, brother of Gaius, was likewise in the service of the Marian party in the war against Sulla, 82 BC, and was legate to Gaius Norbanus. He and other officers of the party of Carbo were invited to a banquet by Publius Albinovanus, and then treacherously murdered.^[44]
