Roman last names are among the oldest and most consequential surnames in Western history. The Roman naming system gave us the concept of the hereditary family name, and many of the surnames carried by ancient Roman families are still recognizable today, surviving in Italian, Spanish, Portuguese, French, and English forms. If you are researching ancestry, building a fictional world, or simply fascinated by the ancient world, these names carry centuries of story in just a few syllables.
This list covers the most significant Roman last names, drawn from the great gentes (clans) of the Republic and Empire, as well as cognomina (personal nicknames that became hereditary) and names that have survived into modern use. Each entry is a real name from the historical record, with its genuine origin and meaning where known.
The Great Patrician Gentes: Rome’s Founding Families
These are the nomen gentilicium names, the clan names that identified Rome’s oldest and most powerful aristocratic families. They defined Roman politics, religion, and warfare for centuries.
Julius
The gens Julia claimed descent from Iulus, son of Aeneas, and ultimately from the goddess Venus. The name is likely Etruscan or Greek in origin, possibly connected to the Greek word for “downy-bearded” or to the name of the god Jupiter. Julius Caesar made this the most famous Roman family name in history.
Cornelius
One of the largest and most prestigious patrician gentes, the Cornelii produced more consuls than almost any other family. The origin is uncertain but possibly Etruscan; the name was so common among Roman nobles that it survived directly into modern use as both a given name and surname.
Claudius
The gens Claudia traced its origins to the Sabine settlement in early Rome. The name derives from the Latin “claudus,” meaning lame or limping, likely a cognomen that became the family name. The Claudii produced emperors, consuls, and censors across several centuries.
Fabius
The gens Fabia is traditionally said to take its name from “faba,” the Latin word for the broad bean, suggesting the family may have been associated with bean cultivation in Rome’s agricultural past. Quintus Fabius Maximus, the Dictator who famously delayed Hannibal, is the family’s most celebrated member.
Aemilius
The Aemilii were one of Rome’s oldest patrician families, and the name is believed to derive from the Latin “aemulus,” meaning rival or striving to equal. Lucius Aemilius Paullus, victor at the Battle of Pydna in 168 BC, is among the gens’s most distinguished members.
Valerius
From the Latin “valere,” meaning to be strong or healthy, the Valerii were a patrician gens prominent from the very founding of the Republic. Publius Valerius Publicola was one of the first consuls of Rome after the expulsion of the kings.
Manlius
The gens Manlia was an ancient patrician family whose name is of uncertain origin, though it may derive from an early Roman praenomen. Marcus Manlius Capitolinus famously defended the Capitoline Hill from the Gauls in 390 BC.
Quinctius
Often spelled Quintius, this patrician gens takes its name from the Latin “quintus,” meaning fifth, likely referring to a fifth son or a birth in the fifth month. Titus Quinctius Flamininus defeated Philip V of Macedon and declared the freedom of Greece in 196 BC.
Furius
The gens Furia was a prominent patrician family whose name may derive from “furia,” meaning fury or frenzy, or from an Etruscan root. Marcus Furius Camillus, the great general who rebuilt Rome after the Gallic sack, was its most famous son.
Servilius
The Servilii were a major patrician gens whose name likely derives from “servus,” meaning slave or servant, though in the family context it may have indicated a client relationship or early servitude to a god. They were consistently prominent through the middle Republic.
Postumius
One of Rome’s oldest patrician families, the Postumii take their name from the Latin “postumus,” meaning last-born or born after. The family produced several consuls and dictators in the early Republic.
Sulpicius
The gens Sulpicia was a patrician family whose name may derive from an Etruscan or Oscan root. Publius Sulpicius Rufus was a notable tribune of the plebs who allied with Marius in the turbulent late Republic.
Papirius
An ancient patrician gens, the Papirii may take their name from “papyrus” or from a pre-Latin root. Lucius Papirius Cursor was one of Rome’s most celebrated commanders during the Samnite Wars.
Nautius
The gens Nautia was a small but ancient patrician family, traditionally associated with the cult of Minerva. The name likely derives from “nauta,” meaning sailor, suggesting early maritime connections.
Famous Plebeian Gentes: The Names That Shaped the Republic
Not all great Roman family names belonged to the patrician order. These plebeian gentes rose through military achievement, political ambition, and sheer staying power to become among the most recognized names in Roman history.
Licinius
The Licinii were a powerful plebeian gens whose name possibly derives from “licium,” a thread or thong, or from an Oscan personal name. Gaius Licinius Stolo co-authored the landmark Licinian-Sextian laws that opened the consulship to plebeians in 367 BC.
Marius
The gens Maria was a relatively obscure plebeian family from Arpinum until Gaius Marius, the “third founder of Rome,” transformed it into one of the most famous names in history. The name likely derives from “mas” or “maris,” meaning male, or may be connected to the god Mars.
Pompeius
The gens Pompeia came from Picenum in northern Italy and rose to prominence through military service. Gnaeus Pompeius Magnus, known to history simply as Pompey the Great, made it a name that rivaled Julius in the late Republic.
Tullius
The Tullii were a plebeian family from Arpinum whose name may derive from a pre-Latin root or the Etruscan “tular,” meaning border. Marcus Tullius Cicero, Rome’s greatest orator, gave this name its lasting cultural weight.
Sempronius
The gens Sempronia was a large plebeian family whose name is of uncertain origin, possibly Oscan or Etruscan. Tiberius and Gaius Sempronius Gracchus, the reforming tribunes of the late second century BC, are its most celebrated and controversial members.
Calpurnius
The Calpurnii traced a legendary descent from Calpus, son of King Numa Pompilius, though historians treat this as retrospective myth-making. The name is likely Etruscan. Gaius Calpurnius Piso led a famous conspiracy against Nero in 65 AD.
Cassius
The gens Cassia was an old plebeian family whose name may derive from the Latin “cassus,” meaning empty or hollow. Gaius Cassius Longinus, one of the principal conspirators against Julius Caesar, is its most historically resonant bearer.
Brutus
The cognomen Brutus, meaning heavy, dull, or brutish in Latin, became so associated with the gens Junia that it functioned as a family name. Lucius Junius Brutus was the legendary founder of the Republic, and Marcus Junius Brutus is forever associated with the Ides of March.
Hortensius
The Hortensii were a plebeian family whose name likely derives from “hortus,” the Latin word for garden. Quintus Hortensius Hortalus was Cicero’s chief rival at the Roman bar and one of the greatest orators of the late Republic.
Plautius
The gens Plautia was a plebeian family of possible Etruscan origin. Aulus Plautius commanded the Roman invasion of Britain under Claudius in 43 AD, making this name directly connected to British history.
Terentius
The Terentii were a plebeian family whose name may derive from the Latin “terere,” to rub or wear away, or from an Etruscan root. Publius Terentius Afer, the playwright known as Terence, is its most culturally enduring member.
Octavius
From “octavus,” meaning eighth, the gens Octavia was a plebeian family from Velitrae. Gaius Octavius became Augustus, the first Roman emperor, after his adoption into the Julian gens, transforming this relatively obscure family name into one of the most significant in world history.
Scribonius
The Scribonii were a plebeian family whose name derives from “scribere,” to write, suggesting an early connection to scribal or clerical work. The family produced consuls and was connected by marriage to the imperial family in the Augustan period.
Oppius
The gens Oppia was a plebeian family whose name may derive from an Oscan root. Gaius Oppius was a close ally and agent of Julius Caesar, handling much of his financial and political business.
Imperial Family Names: The Dynasties That Ruled the Empire
These Roman last names defined entire eras of history. Some were clan names, others cognomina, but all became synonymous with imperial power.
Augustus
Originally a title meaning venerable, sacred, or consecrated, Augustus was granted to Octavian by the Senate in 27 BC and became effectively a dynastic name. Its Latin root is “augere,” to increase or to consecrate by augury.
Caesar
The cognomen of the Julian gens, Caesar is of debated origin: ancient sources variously attributed it to the birth of an ancestor by Caesarean section, to the killing of an elephant (from the Moorish word “caesai”), or to a reference to thick hair. It became a title for Roman emperors and is the root of the German “Kaiser” and the Russian “Tsar.”
Flavius
From “flavus,” meaning golden-haired or blond, the gens Flavia was a plebeian Italian family that produced the Flavian dynasty: Vespasian, Titus, and Domitian. Flavius became so associated with imperial status that later emperors and officials adopted it as an honorific.
Antonius
The gens Antonia was an old plebeian family whose name is of uncertain origin, possibly Etruscan or from a Greek root meaning “of inestimable worth.” Marcus Antonius, known as Mark Antony, made it one of the most famous names of the late Republic.
Domitius
The Domitii Ahenobarbi were a prominent plebeian family whose nomen derives from “domare,” to tame. The cognomen Ahenobarbus means bronze-bearded. Lucius Domitius Ahenobarbus was the birth name of the emperor Nero.
Nerva
The cognomen Nerva, used by the gens Cocceii, derives from “nervus,” meaning sinew or strength. Marcus Cocceius Nerva became emperor in 96 AD and began the era of the Five Good Emperors by adopting Trajan.
Trajanus
The family name of the emperor Trajan, from the Spanish town of Italica, where his family had settled as Roman colonists. The name is likely derived from an Etruscan or Oscan root, and Trajan became the first non-Italian-born Roman emperor.
Hadrianus
The family name of the emperor Hadrian, derived from “Adria,” the Adriatic Sea, via the Italian town of Hadria from which his family came. Hadrian’s Wall in Britain made this name permanently embedded in British heritage.
Aurelius
From the Latin “aureus,” meaning golden, the gens Aurelia was a plebeian family of considerable distinction. Marcus Aurelius, philosopher-emperor and author of the Meditations, is the most admired bearer of this name in history.
Severus
The cognomen Severus, meaning stern or strict, became a family name for the Severan dynasty founded by Lucius Septimius Severus in 193 AD. The dynasty was of North African and Syrian origin, reflecting the broadening of Roman identity by the late empire.
Constantinus
The family and dynastic name associated with Constantine the Great, derived from the Latin “constans,” meaning steadfast or constant. Constantine’s adoption of Christianity and founding of Constantinople reshaped the ancient world.
Valentinianus
The dynastic name of Valentinian I and his successors, derived from “Valentinus,” itself from “valens,” meaning strong or healthy. The family came from Pannonia (modern Hungary/Croatia) and ruled in the fourth century AD.
Famous Cognomina: The Nicknames That Became Surnames
The cognomen was Rome’s third name, originally a personal nickname that described a physical trait, an achievement, or a family characteristic. Many became hereditary and functioned as the most distinctive part of a Roman’s identity.
Cicero
The cognomen of the Tullii Cicerones, derived from “cicer,” the Latin word for chickpea. Ancient sources suggested it referred to a wart-like bump on an ancestor’s nose. Marcus Tullius Cicero reportedly refused to change it, saying he would make the name famous on its own terms.
Cato
From the Latin “catus,” meaning shrewd, wise, or cunning. Marcus Porcius Cato the Elder and his great-grandson Marcus Porcius Cato Uticensis are the two most famous bearers, both known for their austere, uncompromising character.
Scipio
The cognomen of a branch of the Cornelii, from the Latin “scipio,” meaning staff or walking stick, suggesting an ancestor who served as a support to a blind relative. Publius Cornelius Scipio Africanus, who defeated Hannibal at Zama in 202 BC, made this one of Rome’s most celebrated names.
Gracchus
The cognomen of a branch of the Sempronii, of uncertain origin but possibly Etruscan or Oscan. Tiberius and Gaius Gracchus, the reforming tribunes of the late second century BC, made it synonymous with populist politics.
Sulla
The cognomen of Lucius Cornelius Sulla Felix, the dictator who marched on Rome twice and rewrote the constitution. The origin of the name is uncertain, possibly Etruscan. Sulla added “Felix,” meaning happy or fortunate, to his cognomen after his victories.
Agrippa
A cognomen of uncertain origin, possibly from a Greek root meaning “born feet first” or from an Etruscan source. Marcus Vipsanius Agrippa was Augustus’s greatest general and son-in-law, the man most responsible for winning the Battle of Actium.
Labienus
The cognomen of a Picentine family, probably derived from a place name. Titus Labienus was Caesar’s most trusted lieutenant in Gaul before defecting to Pompey at the outbreak of civil war.
Cincinnatus
From the Latin “cincinnus,” meaning curly-haired. Lucius Quinctius Cincinnatus, the farmer-dictator who left his plow to save Rome and then returned to his farm immediately after, became the Roman ideal of civic virtue.
Lucullus
The cognomen of a branch of the Licinii, probably derived from the Latin “lucus,” meaning grove. Lucius Licinius Lucullus is remembered for his extraordinary wealth and lavish banquets after his campaigns in the East, giving the English language the word “Lucullan.”
Coriolanus
The cognomen awarded to Gnaeus Marcius for his capture of the Volscian city of Corioli. The name is simply derived from that city’s name, per the Roman tradition of commemorating a general’s greatest conquest in his cognomen.
Africanus
A cognomen awarded for victory in Africa, most famously to Publius Cornelius Scipio after his defeat of Hannibal. The tradition of geographic cognomina continued with names like Asiaticus, Macedonicus, and Numidicus.
Maximus
From the Latin superlative “maximus,” meaning greatest. Used both as a cognomen and eventually as a given name, it was awarded as an honorific and became hereditary in several families, most famously the Fabii Maximi.
Regulus
The diminutive of “rex,” meaning little king or prince. Marcus Atilius Regulus, the consul who was famously captured by Carthage during the First Punic War and returned to his captors rather than break his oath, made this one of Rome’s most celebrated names for valor.
Lepidus
From the Latin “lepidus,” meaning charming, pleasant, or elegant. Marcus Aemilius Lepidus was the third member of the Second Triumvirate alongside Antony and Octavian, though he was eventually sidelined by both.
Scaevola
From the Latin “scaevus,” meaning left-handed. The cognomen commemorates the legendary Gaius Mucius Scaevola, who held his right hand in a fire to demonstrate Roman courage to the Etruscan king Porsenna.
Republican-Era Names of Enduring Significance
These Roman last names come from the centuries of the Republic and carry the weight of Roman political and military culture at its most dynamic.

Quintilius
The gens Quintilia was connected to the Latin praenomen Quintus. Publius Quintilius Varus suffered the catastrophic defeat in the Teutoburg Forest in 9 AD, losing three Roman legions and marking the effective limit of Roman expansion into Germany.

The cognomen-turned-family-name of Quintus Sertorius, the brilliant Marian general who held most of Spain against Sulla and then against Pompey’s forces for a decade. The origin of the name is uncertain.
Names That Survived into Modern Use
These Roman last names made the journey from antiquity into the modern world, surviving as surnames in Italy, Spain, Portugal, France, and beyond. Many are still common family names today.
Rossi
The most common surname in Italy, derived from the Latin “russus” or “roseus,” meaning red, originally a nickname for someone with red hair. It is the direct Italian descendant of the Roman cognominal tradition of naming by physical appearance.
Ferrari
From the Latin “ferrarius,” meaning blacksmith or ironworker, derived from “ferrum,” iron. It was a common occupational surname in Roman and medieval Italy and is one of the most widely distributed Italian family names.
Romano
Directly from “Romanus,” meaning Roman or citizen of Rome. Used as both a given name and surname throughout the Roman Empire, it became a common surname throughout Italy and the Hispanic world as a marker of Roman identity or origin.
Florio
From the Latin “flos” or “floris,” meaning flower, via the Roman cognomen Florius. It became a common Italian and Spanish surname and is directly traceable to Roman naming conventions.

Derived from the Latin “Aquinum,” a town in Latium whose name comes from “aqua,” water. The family name became famous through Saint Thomas Aquinas (Thomas of Aquino), the thirteenth-century philosopher and theologian.
Silvio
From the Latin “silva,” meaning forest or wood. The cognomen Silvius was used by several early Roman figures, including the legendary kings of Alba Longa who were said to descend from Aeneas, and it became a common given and family name throughout the Romance world.
Luca
While commonly a given name today, Luca as a surname derives from the Latin “Lucas,” which is connected to “lux,” meaning light. It was used as a Roman family name and remains one of the most common surnames in parts of southern Italy.
Rufus
From the Latin “rufus,” meaning red-haired. One of the most common Roman cognomina, given to ancestors with red hair, it survived as both a given name and a surname in Italy, Spain, and England.
Calvus
From the Latin “calvus,” meaning bald. A common Roman cognomen describing a bald ancestor, it was used by Gaius Licinius Calvus, the orator and poet who was Cicero’s contemporary.
Albus
From the Latin “albus,” meaning white or bright. Used as a Roman cognomen to describe fair-haired or fair-skinned individuals, it persisted as a given name and surname in medieval and early modern Italy.

From the Latin “parvus,” meaning small. A common cognomen for a notably small ancestor, it survived in Italian surnames and was used by Lucius Cornelius Sulla’s advisor Publius Cornelius Sulla, among others.
Names from Rome’s Provinces and Allies
As Rome expanded, it absorbed families from across the Mediterranean. These names reflect the broader reality of Roman identity, which was always more inclusive than the myth of pure Latin origin suggests.
Septimius
From “septimus,” meaning seventh. The North African family of Lucius Septimius Severus, who became emperor in 193 AD, brought this name to the pinnacle of Roman power. It is one of the clearest examples of provincial Roman families ascending to the highest offices.
Ulpius
The family name of the emperor Trajan, from the Spanish province of Baetica. Marcus Ulpius Traianus and his father of the same name came from Italica in modern Andalusia, and the name is likely Etruscan or pre-Latin in origin.
Caecilius
The gens Caecilia was one of Rome’s most distinguished plebeian families, whose name possibly derives from “caecus,” meaning blind. Quintus Caecilius Metellus Numidicus was one of several Metelli who dominated late Republican politics.
Metellus
A cognomen of the Caecilii that became almost a family name in itself, from the Latin “metellus,” possibly meaning a hired soldier or mercenary. The Metelli were one of the most powerful political dynasties of the late Republic.
Bassus

Cursor
From the Latin “cursor,” meaning runner. The cognomen of Lucius Papirius Cursor, twice dictator and one of Rome’s greatest commanders in the Samnite Wars, who was said to have been exceptional in speed and endurance.
Pulcher
From the Latin “pulcher,” meaning beautiful or handsome. A cognomen used by several members of the Claudia gens, most notoriously Publius Clodius Pulcher, the populist tribune and enemy of Cicero.
How to Choose a Roman Last Name for Your Project
If you are using Roman last names for fiction, gaming, historical research, or even considering them as a source for character names, the structure of the Roman naming system is your best guide. Romans typically had three names: the praenomen (personal name), the nomen (clan name), and the cognomen (individual or branch nickname). When picking a Roman family name, decide which layer you need. For a patrician character, a nomen like Cornelius, Julius, or Valerius signals old blood and prestige. For a new man or a provincial, something like Septimius or Ulpius suggests ambition from outside the traditional aristocracy.
Pay attention to the cognomen tradition if you want something more distinctive. Cognomina like Cicero, Cato, Scipio, or Agrippa carry specific historical weight, and readers familiar with Roman history will recognize them immediately. If you want a name that feels Roman without directly invoking a famous figure, choose a less-known cognomen like Regulus, Lepidus, or Macer, which have the right sound and structure without the historical baggage.
For modern surnames with Roman roots, the Italian, Spanish, and Portuguese traditions are rich sources. Names like Rossi, Ferrari, Romano, and Rufus are directly descended from Roman naming practices and carry that ancestry without feeling like a costume. They work equally well for real-world use, whether you are researching a family’s Italian roots or simply want a surname with genuine ancient weight behind it.
One practical note: Roman names were gendered. The nomen was typically feminized by changing the ending to “-a” (so Cornelius becomes Cornelia, Julius becomes Julia). If you are naming a female character in a Roman or Roman-inspired setting, applying this rule will immediately make the name feel authentic.
Roman last names are not just historical curiosities. They are the foundation of the Western surname tradition, the origin of the very idea that a family name could carry identity, status, and memory across generations. Every time you encounter a name ending in “-ius” or a modern Italian surname derived from Latin, you are seeing the Roman system still at work, two thousand years later.
