The Juventii were said to have come to Rome from Tusculum, probably during the fourth century BC. Cicero reports a claim, which he regards as incorrect, that the first of the plebeian aediles was a Juventius, and in fact the Juventii are not mentioned until BC 197, although there is no reason to doubt that the family had already been at Rome for some generations.^[i][4][1] The nomen Juventius is certainly derived from the Latin juventas, "youth", personified by the goddess Juventas,^[5] but the family is probably of Etruscan origin, as the surname Thalna, borne by a number of the earliest Juventii, has the same meaning; Juventius is simply the Latin version of their original name.

The earlier Juventii used the praenomina Titus, Lucius, Manius, Publius, and Gaius. From the first century BC we also find Marcus. All were very common names, except for Manius, which was used by many fewer families.

There were several families of the Juventii in the time of the Republic, with the surnames Celsus, Laterensis, Pedo, and Thalna. However, several Juventii are mentioned without any surname.^[1] Thalna, occasionally found as Talna, is an Etruscan name,^[6] and was probably the original nomen of the gens, before it came to be known as Juventia.

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

Juventii Thalnae edit

• Titus Juventius (Thalna?), a military tribune serving under the consul Quintus Minucius Rufus in BC 197. He was slain in battle against the Cisalpine Gauls.^[7][8]

Juventii Celsi edit

• Juventius Celsus, a celebrated jurist during the latter part of the first century AD, and the father of the even more influential jurist Publius Juventius Celsus.
• Publius Juventius Celsus, one of the most influential of all the Roman jurists, flourished during the reigns of Nerva, Trajan, and Hadrian. He was twice consul, although the years are stated differently.
• Publius Juventius Celsus, consul in AD 164.

Juventii Laterenses edit

• Manius Juventius L. f. Laterensis, triumvir monetalis in 83 BC, and probably governor of Asia, circa 77.^[27][28]
• Marcus Juventius M'. f. L. n. Laterensis, a friend of Cicero and political opponent of Caesar, was quaestor in an uncertain year, and after several setbacks, obtained the praetorship in BC 51. After Caesar's murder, he was a legate of Marcus Aemilius Lepidus, and took his own life when Marcus Antonius entered Lepidus' camp.^{[29][30][31][32][28]}
• Lucius Juventius Laterensis, a legate under Quintus Cassius Longinus in Hispania Ulterior during the Civil War, was proclaimed praetor by the soldiers when they believed that Cassius had been put to death. But as Cassius escaped the assassins, he immediately ordered the execution of Laterensis, along with the conspirators.^[33]
