Felix is a two syllable Latin name that means lucky, and it carries that meaning lightly. It sounds at home on a jazz record, in a Roman history book, and on a preschool cubby label, which is why parents who like vintage names with some spark keep circling back to it.
The name is having its biggest moment right now. More boys were named Felix in 2024 than in any other year of the comparable federal record, and it still sits well outside the top 100, so a boy named Felix is unlikely to share his name with a classmate.
Verdict: Felix is a strong pick for a baby born in 2026. It is easy to spell, easy to say, and cheerful by definition, which makes it a lighter choice than William or James for parents who want history without formality.

What Does Felix Mean?
Felix means lucky, fortunate, or happy. The Latin adjective felix began as a farming word for soil and trees that were fruitful (1), and a field that produced well was a field the gods had smiled on, so the sense slid from fertile to favored to lucky.
That agricultural root is why the name reads as a quiet blessing rather than a bold claim. It says a child is fortunate, not that he is formidable, and very few names manage that.
Romans used it as a personal nickname for a man whose luck held, and the meaning has not shifted since.
Where Does the Name Felix Come From?
Felix comes from ancient Rome, where it started as a cognomen, the third slot in the Roman three name system that began as a personal nickname and often hardened into a family name.
The most famous Roman to claim it was the dictator Lucius Cornelius Sulla, who took the name Felix in late 82 BC out of a belief in his own luck (2). He was not being modest. He meant that the gods had backed him in the civil war, and he wanted the record to say so.
Early Christians then adopted the name for the opposite reason, because blessed was exactly what a persecuted community wanted said about its dead. Three popes took the name and are honored as saints: Felix I, Felix III, and Felix IV. The Catholic canon counts 47 saints named Felix in all (3).
That church history is how a Roman nickname turned into a classic name across Europe, settling into local forms in France, Spain, Italy, and Poland that are still in use today.
How Popular is the Name Felix?
Felix ranked 175th for boys in the United States in 2025, when 2,064 babies received the name, or roughly one boy in every 828 (4).
The curve is a long dip and a full recovery. Felix was a top 200 name before World War I, thinned out through the middle of the century, and has been climbing back since the 2000s. Point at any year on the chart and you can read the count for yourself.
Two numbers tell the story together. The name’s best rank ever was 172nd, set in 1914. Its biggest year by birth rate is 2024, when 2,090 boys were named Felix, more than in any other year of the comparable record. Both are true because there are far more names in circulation now than a century ago, so a bigger crowd of babies spreads across a longer list and a modern rank of 175 sits on more births than an old rank of 172 did.
Felix has appeared in all 146 years of the federal data, from 1880 through 2025, and 83,508 boys have carried it. Half of everyone ever recorded with the name was born after 1984.
For a parent deciding today, that combination is the appeal. Felix is recognizable enough that nobody will ask you to spell it twice, rising enough that it does not sound like a name pulled off a headstone, and far enough down the list that your son is unlikely to be one of three in a classroom.
Which Names Rose and Fell With Felix?
Ezra, Kayson, and Leo have tracked Felix most closely over the last 45 years of birth data, and all three are plotted on the chart below. This is our own reading of public birth records, not an official grouping, and the point is timing rather than sound: these are the names whose curves moved when Felix moved.
- Ezra: peaked in 2024, the same year Felix did, hit its best rank of 13th that year, and sits at 20th in 2025. Still rising.
- Kayson: a much smaller name with the same shape. Its best rank so far is 264th, set in 2025, which is also its peak year.
- Leo: the biggest name of the group. Its best rank was 18th in 2023 and it sits at 19th in 2025, still rising.
- Jasper: not plotted above, but the same trajectory. Best rank 122nd in 2023, 129th in 2025.
- Asher: best rank 20th in 2022 and 28th in 2025, still on a rising trend.
- Muhammad: also unplotted. Its best rank is 239th, set in 2025, so it is at its high point now.
Every one of the six is rising, which says something about Felix itself. Parents drawn to it are shopping in a corner of the list where names are gaining across the board right now.
How Do I Pronounce Felix?
Felix is pronounced FEE-liks, with the stress on the first syllable and a long e. It is spelled how it sounds, so it survives roll call, coffee shops, and voicemail without correction.
European languages shift the vowels or the stress:
- Spanish and Italian: FEH-leeks
- German: FAY-liks (German speakers use a softer opening vowel)
- French: fay-LEEKS (French speakers put the stress on the second syllable)
Is Felix a Boy or Girl Name?
Felix is a boy name in the United States, and the records are lopsided rather than absolute. In 2025, 2,064 boys were given the name against 10 girls, which placed Felix at 9,667th on the girls’ list. Across the whole record, girls account for 672 Felixes, or 0.8 percent of everyone who has carried it.
So a girl named Felix is legal, findable in the data, and genuinely rare. Parents who want the same meaning in a clearly feminine name usually land on Felicity, the direct Latin equivalent, or on Felicia and Felicitas.
