Brazil registers about 2.5 million births a year (IBGE civil registry statistics, 2023), and the names parents choose say a lot about the country: a mix of Portuguese classics, biblical names spelled the international way, Italian and English imports, and a uniquely Brazilian habit of compound names starting with Maria. This guide covers the most popular Brazilian baby names of 2026, what they mean, the trends behind them, and how naming rules work at the civil registry (cartório).

Where the data comes from

Brazil has no single “official top 10” published by the government each year. The closest thing is the transparency portal of the Arpen Brasil, the national association of civil registrars, which publishes the most registered names by period and by state. The IBGE (Brazil’s statistics institute) also maintains a public tool called Nomes no Brasil, based on census data, that shows how many people carry each name and in which decade it peaked. This article uses both sources for direction, not for exact rankings: positions change monthly and vary a lot between regions.

Most popular girl names in Brazil

The girls’ list is led by short classics that were common two generations ago and came back with force.

  • Helena — “the shining one” (Greek). Among the most registered names in the country for years.
  • Alice — “of noble kind” (Germanic).
  • Laura — “laurel”, symbol of victory (Latin).
  • Maria Alice — the leading compound name; Maria + Alice.
  • Cecília — Roman family name; associated with the patron saint of music.
  • Maitê — “beloved” (Basque). One of the fastest-rising names of recent years.
  • Heloísa — “famous warrior” (Germanic).
  • Aurora — “dawn” (Latin).
  • Maria Cecília and Maria Clara — compound names that stay in the top group year after year.
  • Liz, Ayla, Isis and Eloá — the short, international-sounding names that define the decade.

Names that dominated the 2010s, such as Sophia, Valentina, Júlia and Manuela, are still widely used but have slipped below their peak.

Most popular boy names in Brazil

  • Miguel — “who is like God?” (Hebrew). The number one boy’s name in Brazil for more than a decade.
  • Arthur — “bear” (Celtic).
  • Gael — “generous” or “foreigner” (Breton/Gaelic). Went from rare to top ten in a few years.
  • Theo — short form of Teodoro, “gift of God”.
  • Heitor — Portuguese form of Hector, “he who holds” (Greek).
  • Ravi — “sun” (Sanskrit). The most surprising entry of recent lists, especially strong in the Southeast.
  • Davi — “beloved” (Hebrew). Brazilian spelling of David.
  • Bernardo — “strong as a bear” (Germanic).
  • Noah — “rest” (Hebrew). The international spelling has overtaken the Portuguese Noé.
  • Gabriel, Samuel, Pedro, Benício and Anthony — steady presences in the top group.

Eight naming trends in Brazil for 2026

  1. Very short names. Three or four letters, one or two syllables: Liz, Theo, Gael, Ravi, Léo. Easy to pronounce in Portuguese, English and Spanish.
  2. Grandparents’ classics are back. Helena, Cecília, Antônio, Vicente, Bento and Olívia. The rarer a name became in the 1990s, the newer it sounds today.
  3. Nature and light. Aurora, Luna, Sol, Flor, Celeste.
  4. Indigenous names. Tainá (“star” in Tupi), Iara, Kauê, Kauã. A slow but steady revival, strongest in the North and Northeast.
  5. Compound names with Maria. Maria Alice, Maria Cecília, Maria Flor. A distinctly Brazilian way to combine a classic and a modern name.
  6. Biblical names with modern spelling. Isaac, Levi, Eloá, Esther, Asafe. Brazil is one of the countries where biblical names grow fastest, driven in part by the evangelical population.
  7. International names from screens. Noah, Oliver, Anthony, Thomas, Antonella, Lorenzo. Streaming, sports and binational families brought names that work in English and Italian.
  8. Simpler spellings. After years of decorative “y” and “h” (Kauany, Thayla, Rhuan), simpler forms are gaining: Kauã, Taila, Ruan.

How naming rules work in Brazil

Births are registered at a civil registry office (cartório de registro civil); many maternity hospitals have a registry desk on site. The legal deadline is 15 days after birth, extended to up to three months when the registry is far from the family’s home. The first birth certificate is issued without a fee under federal law.

Under the Public Records Act (Lei 6.015/1973), the registrar may refuse a name only if it would expose the child to ridicule; in that case the family can appeal to a judge. There is no requirement that a name indicate the child’s sex, so unisex names are accepted, as are foreign names and spellings with k, w and y. Parents can order the surnames freely (mother’s first, father’s first, or only one of them). Since 2022, adults can change their own first name once directly at the registry, without a court process.

How birth registration works in Brazil

Six things every family does at the cartório

1. Register within 15 days

The legal deadline runs from the birth and stretches to three months when the registry office is more than 30 km from home (Lei 6.015/1973).

2. Use the hospital desk if there is one

Many maternity hospitals host a registry desk, so the birth can be registered before discharge.

3. Settle the spelling first

Sophia or Sofia, Theo or Théo: the registered spelling is the one that appears on every document, and changing it later requires a formal procedure.

4. Know what can be refused

Only a name that would expose the child to ridicule. Unisex, foreign and compound names are accepted, and the family can appeal a refusal to a judge.

5. The first certificate has no fee

Federal law (Lei 9.534/1997) makes the birth registration and the first birth certificate free of charge.

6. Adults can change their first name once

Since 2022, anyone over 18 can change their first name directly at the registry, one time, without a court process.

Frequently asked questions

Is there an official ranking of Brazilian baby names?
Not a single government ranking. The Arpen Brasil transparency portal publishes the most registered names by period and state, and the IBGE census tool shows historical frequency. Rankings differ by region and change month to month.

Why are compound names so common in Brazil?
Compound names, especially with Maria (Maria Alice, Maria Cecília) and João (João Miguel), let families keep a traditional name while adding a modern one. They are registered as a single first name.

Can foreigners living in Brazil choose any name?
Yes. The same rules apply: the only ground for refusal is a name that exposes the child to ridicule. Names from any language are accepted with the spelling the parents choose.
