Welcome to Reedsy’s ultimate bank of Old Roman names
Rome ran an empire of fifty million people on roughly eighteen first names. Everything interesting happened in the other two: the family name that tied you to a centuries-old gens, and the nickname — often an insult — that stuck to your branch of it forever. Cicero's family were "the Chickpeas." They kept it, because in Rome even a wart on an ancestor's nose was heritage.
Our Roman name generator builds period-accurate names for your character's class, era, and story. Prefer to browse? The bank below holds eighty authentic Roman names — first names, family names, nicknames, and women's names — with the meaning and the machinery behind each.
Inside the bank: 1,000,000+ Roman names with meanings
A Roman citizen of the classical era carried three names — the tria nomina.
Gaius Julius Caesar, for instance, breaks down as: praenomen (Gaius, the personal name, chosen from a tiny fixed set), nomen (Julius, the clan — the gens Julia), and cognomen (Caesar, the hereditary nickname distinguishing one branch of the clan). The praenomen mattered so little that Romans abbreviated it to a letter or two in writing; the nomen carried your politics, patrons, and ancestors; and the cognomen carried the story.
Enslaved people, meanwhile, had a single name, while freedmen took their former master's praenomen and nomen and kept their own name as a cognomen. A name alone tells a reader a Roman's entire legal biography.
Best Roman first names (praenomina)
Rome used about eighteen praenomina, several of which are just numbers: Quintus, Sextus, and Decimus are "Fifth," "Sixth," and "Tenth." Parents ran out of enthusiasm, not children. The standard abbreviations are worth knowing because Roman writers used them constantly — and note the trap: C. stands for Gaius, Cn. for Gnaeus, fossils from before Latin distinguished C and G.
| Name | Abbreviation | Meaning / note |
|---|---|---|
| Gaius | C. | Possibly "rejoicing" — the default Roman everyman name |
| Lucius | L. | "Light" — born at dawn, said the Romans |
| Marcus | M. | From Mars — the war god in civilian clothes |
| Publius | P. | "Of the people" |
| Quintus | Q. | "Fifth" — birth order as identity |
| Titus | T. | Ancient, meaning uncertain |
| Tiberius | Ti. | "Of the Tiber" — the river as godfather |
| Sextus | Sex. | "Sixth" |
| Aulus | A. | Possibly Etruscan |
| Decimus | D. | "Tenth" |
| Gnaeus | Cn. | Possibly "birthmark" — note the C-for-G abbreviation |
| Spurius | Sp. | Archaic; later avoided for its "illegitimate" echo |
| Manius | M'. | "Born in the morning" — abbreviated with an apostrophe |
| Servius | Ser. | Possibly "preserved" (of a child born after a father's death) |
| Appius | Ap. | Sabine origin; nearly exclusive to the Claudii |
| Numerius | N. | Rare; linked to accounting-minded families, said Rome |
| Vibius | V. | Rare, Oscan-flavored |
| Kaeso | K. | Archaic; one of the few Latin K's |
| Postumus | Post. | "Born after" — for sons born after a father's death |
| Faustus | F. | "Fortunate" — revived by Sulla for his twins |
Best Roman family names (nomina)
The nomen named your gens — the clan — and Rome's history is largely a directory of them. Some carried divine marketing (the Julii claimed descent from Venus); others are charmingly humble: the Fabii, one of the grandest houses in Rome, are probably "the Bean family."
| Name | Gens | Meaning / note |
|---|---|---|
| Julius | Julia | Claimed descent from Venus through Iulus — divine ancestry as branding |
| Claudius | Claudia | Sabine roots; possibly "lame" — nobility kept it anyway |
| Cornelius | Cornelia | Perhaps from cornu, "horn"; the largest patrician gens |
| Aurelius | Aurelia | "Golden" — later the philosopher-emperor's name |
| Flavius | Flavia | "Blond" — an entire dynasty named for hair |
| Valerius | Valeria | From valere, "to be strong" |
| Antonius | Antonia | Etymology unknown; Marc Antony made it immortal |
| Aemilius | Aemilia | Possibly "rival" — fitting for Roman politics |
| Fabius | Fabia | Probably from faba, "bean" — grandeur from the garden |
| Junius | Junia | Linked to Juno; Brutus's gens |
| Licinius | Licinia | Possibly "upturned" (of hair) |
| Livius | Livia | Possibly "bluish" — the historian's and the empress's name |
| Pompeius | Pompeia | Oscan "five" — another number hiding in a name |
| Sempronius | Sempronia | The Gracchi brothers' gens |
| Sergius | Sergia | Catiline's gens — infamy included |
| Tullius | Tullia | Cicero's gens; archaic royal echo (Servius Tullius) |
| Octavius | Octavia | "Eighth" — the future Augustus started here |
| Cassius | Cassia | Perhaps "hollow"; conspirator's edge ever since |
| Horatius | Horatia | The bridge-holder and the poet |
| Domitius | Domitia | From domare, "to tame" — Nero's paternal line |
Best Roman nicknames (cognomina)
The cognomen began as a personal nickname and then became hereditary, so descendants carried an ancestor's bald head or famous nose for centuries. This is the table novelists should steal from: Rome's greatest families answered, with straight faces, to Chickpea, Fatso, and Little Boots.
| Name | Meaning | Famous bearer / note |
|---|---|---|
| Caesar | Possibly "fine head of hair" | Worn by a famously balding Julius — Rome enjoyed the joke |
| Cicero | "Chickpea" | An ancestor's wart; the orator refused to change it |
| Brutus | "Heavy, dull" | Ancestral camouflage — the first Brutus played dumb to survive a tyrant |
| Naso | "The nose" | The poet Ovid, officially P. Ovidius The-Nose |
| Crassus | "Fat, thick" | Rome's richest man, forever Fatso |
| Magnus | "The Great" | The rare earned honorific — Pompey took it young |
| Rufus | "Red-haired" | The commonest coloring cognomen |
| Ahenobarbus | "Bronze-beard" | Nero's family line; the beard was legend |
| Scaevola | "Left-handed" | Earned, per legend, by burning off the right hand to defy a king |
| Cato | "The shrewd" | Sternness as a family trademark |
| Calvus | "Bald" | Rome named what it saw |
| Paullus | "Small" | Grand family, modest label |
| Felix | "Lucky" | Sulla appointed himself Fortune's favorite |
| Severus | "Stern" | Later an imperial dynasty |
| Maximus | "Greatest" | Earned by the Fabius who beat Hannibal by waiting |
| Albus | "White" | Yes — that's where the headmaster's name comes from |
| Niger | "Black" | Coloring, plainly stated |
| Barbatus | "Bearded" | Notable when Rome shaved |
| Corvinus | "Raven" | Won a duel, legend says, with a raven's help |
| Caligula | "Little boots" | The army's pet name for a child mascot — kept by an emperor who came to hate it |
Best Roman female names
Roman women officially bore one name: the feminine form of the father's nomen. Every daughter of a Julius was Julia; sisters were told apart as Major and Minor, or numbered — Prima, Secunda, Tertia — birth order as a name. For novelists this is either a documentation problem or a gift: the informality underneath (family pet names, cognomina like Drusilla) is where a Roman woman's individuality lived.
| Name | From the gens | Famous bearer / note |
|---|---|---|
| Julia | Julia | Caesar's daughter — and his aunt, and Augustus's daughter; the name's ubiquity is the lesson |
| Cornelia | Cornelia | Mother of the Gracchi — Rome's model matron |
| Claudia | Claudia | Patrician stamp; still current worldwide |
| Livia | Livia | Augustus's empress; power behind the principate |
| Octavia | Octavia | Augustus's sister, married to Antony — diplomacy by name |
| Antonia | Antonia | Antony's daughters, Minor and Major, both influential |
| Valeria | Valeria | "Strong" carried into the feminine |
| Aemilia | Aemilia | Root of every modern Emilia and Emily |
| Flavia | Flavia | "Golden-blond," dynastic |
| Aurelia | Aurelia | Caesar's formidable mother |
| Fabia | Fabia | The Bean family's daughters |
| Tullia | Tullia | Cicero's adored daughter |
| Cassia | Cassia | Modern revival candidate |
| Marcia | Marcia | Mars, feminized and gentled |
| Lucilla | diminutive of Lucia | "Little light" — imperial daughter's name |
| Agrippina | cognomen-derived | Two of them shaped the empire; neither gently |
| Faustina | "fortunate" | Empresses, mother and daughter |
| Sabina | "Sabine woman" | Hadrian's empress |
| Drusilla | Drusus diminutive | The affectionate register Roman records rarely show |
| Prima / Secunda / Tertia | any gens | "First, Second, Third" — sisters by the numbers |
How do I come up with a good Old Roman name?
Roman naming is a social system as much as a personal identifier.
A few things worth knowing as you write:
- The praenomen was almost never used in formal address. Romans addressed each other by cognomen among peers, by nomen in more formal contexts. Using a character's praenomen — their Marcus or Gaius — was reserved for intimate settings, close family, and moments of unusual informality.
- Women's naming followed different rules. Roman women of the Republican period typically had only one name — the feminine form of their father's nomen. Julius Caesar's daughter was simply Julia. If there were multiple daughters, they might be distinguished as Julia Maior and Julia Minor. This is strikingly different from male naming.
- Cognomina often began as insults or physical descriptions. Cicero means chickpea. Nasica means pointed nose. Romans wore their cognomina with pride regardless of their origin!
- The period within Roman history shapes the naming culture. Early Republican naming is more austere, while the late Republic and early Empire see an explosion of cognomina and more elaborate naming. If your story is set in a specific period, that specificity should inform the names.
- For fantasy writers building Roman-inspired worlds, the tria nomina system is one of the most useful structural tools available. You don't need to replicate the system exactly you need to understand what it does and build something that does equivalent work.
A note on our use of AI
We built this tool for writers, which means we thought carefully about what AI should and shouldn't do here. The generator uses AI to produce names that better fit your character's specific context and needs — archetype, personality, genre, world — while explaining its reasoning for each one.
Here’s what it won’t do for you: it won’t write your story, name your character, or make creative decisions for you. It simply generates options for you.
More importantly, your inputs are not (and will never be) used to train any AI models. Treat whatever comes out as raw material: a starting point that belongs entirely to you. Every result is yours!
