Adriano is a dashing Italian name which gets around the possible gender confusion of Adrian.

Adriano

What's the difference between Alexander, the usual English spelling of this deeply classical name, and Alexandre, the French version? English speakers might find the proper French pronunciation challenging: a-lehk-SAHN-dreh, but that last syllable is barely pronounced. Americans might an an a or an ee on the end of the name, or simply pronounce it as Alexander, for better or worse.

Alexandre

Daniel is one of only a handful of male names that sounds both classic and modern, strong yet approachable, and popular but not cliched. It also has a solid Old Testament pedigree. The only real downside: There are about 10,000 Daniels named each year, making it a less than distinctive choice. 
 
Daniel is derived from the Hebrew name Daniyyel, from the elements din, meaning "judge," and ’el, "God." The Book of Daniel in the Old Testament describes the Jewish prophet’s life of captivity in Babylon and visions of the last days of Earth. 
 Daniel was the name of one of the greatest biblical heroes, with the inspiring story of the prophet whose faith protected him when he was thrown into a den of lions. Yet Daniel does not seem as solemn and weighty a name as other Old Testament names like Abraham and Ezekiel. 

Popular since the days of Daniel Webster and Daniel Boone,
Daniel is a perennial favorite, in the Top 15 <a href="https://nameberry.com/boys-names">names for boys</a> every year since 1972. Daniel ranks first among all <a href="https://nameberry.com/search/boys-names/d">baby names starting with D</a>. 

Daniel's appeal is international, from Ireland to Israel, Finland to Chile. And its nicknames—Danny and Dan—make it sound even friendlier, though, as with other classics, many modern parents are opting to use the name in full.

Daniel

A viable David alternative with a hint of worldliness.

Davi

David is an enduring worldwide classic, used from ancient times to the present day.
 David is derived from the Hebrew name Dawid, believed to come from the root dôwd, meaning “beloved”. The first famous David was the Old Testament second king of Israel: the shepherd boy who killed the giant Goliath, and later a warrior, poet, and powerful leader, wise but humanly fallible. He is an important figure in Judaism, Islam and Christianity, and later inspired many works of art, including Michelangelo’s colossal sculpture.
 Since then, there have been countless Davids of note in history, literature, and popular culture, including the patron saint of Wales — a translation of the Welsh name Dewi — two kings of Scotland. Then there’s Copperfield, Crockett, Bowie, Beckham, Letterman, Grohl, and many more. Celebrities who have chosen it for their sons include Jennifer Hudson, Bar Refaeli, and J.K. Rowling.
 In its international forms, David is steadily popular around the world, and ranks in the Top 10 names in Brazil, Austria, Armenia, Croatia, Bosnia and Herzegovina, and Israel.
 In the USA, David has never been out of the Top 40 boy names, but was at peak popularity in the mid-twentieth century, ranking in the Top 10 from 1936-1992. This means that, although it’s still given to thousands of boys each year, it has an “older man” feel to it. It ranks highest in states with a large Jewish population, and is still a Top 10 name in New York.
 After Daniel, David is the second most popular <a href="https://nameberry.com/search/boys-names/d">boy name starting with D</a>. Although fading a little in popularity, it remains a serious-yet-friendly classic with deep roots.
 If you’re looking to update David, perhaps as an honor name, the freshest alternatives are surnames deriving from David, including Dawes, Dawson, and Davies. You could also try an international variation, like Welsh Dai or Finnish Taavi.

David

A stalwart of Latin nomenclature that could work just as well for Anglos. Proof lies with the celebrity birth announcement — Hilaria and Alec Baldwin named their fifth child Eduardo Pau Lucas in 2020. This doesn't seem to have much impact on other parents, though: over 900 boys received the name in 2021, but the number is steadily decreasing.

Eduardo

Francisco is one of the more popular <a href="https://nameberry.com/baby-names/496/spanish-names-for-boys">Spanish names for boys</a> in the US, which is unsurprising given its popularity back in Spain and Portugal as well as Latin America, coupled with its classic status. It also has a cool hipster vibe to it, given the reputation of the city of San Francisco.

Flávio

Gabriel has become a biblical favorite, an angelic choice that's lighter and less patriarchal than some of his Old Testament brethren. Derived from the Hebrew name Gavri’el, Gabriel is taken from the elements gever, meaning "strong," and ’el, in reference to God.
 
In Abrahamic religions, Gabriel is the archangel who heralded the news of Jesus' birth, and appears in Christian, Jewish and Muslim texts. He presides over Paradise, serving as the angel of mercy, life, joy, judgment, truth and dreams. 
 In addition to all his other responsibilities, Gabriel is the patron saint of broadcasters and diplomats, and he governs Mondays and the month of January, making Gabriel one of the top <a href="https://nameberry.com/list/629/71-wonderful-names-for-january-babies">January baby names</a>. 
 
Gabriel has proven itself a friendly and appealing alternative to Michael, that other, long-reigning archangel. Gabriel enjoys remarkable international popularity, ranking in the Top 100 in countries as diverse as Israel and Iceland, Chile and Croatia. It is currently the Number 1 boys' name in France.
 Parents of Gabriels of varying ages include Mick Jagger and Jerry Hall, Daniel Day-Lewis and Isabelle Adjani, Jason Alexander, Meredith Vieira, and Mia Farrow.

A Portuguese classic. Many members of the Portuguese royal family were named João, and today it’s associated with a number of Portuguese and Brazilian footballers.

João

Júlio

Leandro is the Portuguese, Italian, and Spanish variant of the English name Leander. A blend of two Latin words (Leo "lion" and Andro "man"), Leandro is a name that suggests its bearer has strength and power. Despite this very masculine meaning, Leandro also has a long romantic history, beginning with the myth of Hero and Leander (Ero et Leandro in Latin) to being an important figure in the history of the beautiful Spanish city of Seville.
 With names like Arlo, Lorenzo, and Pedro growing in popularity, we think there might be a place for Leandro!

Leandro

Lucas is a Top 10 boys' name with a slightly-less-popular almost-identical twin brother, Luke. Like Elijah and Elias, Lucas and Luke come from the same root and have the same meaning and so feel even more popular than they are.
 
The Latin derivation of the Greek Loukas, the name's meaning references Lucania, an ancient territory in Southern Italy. Along with Luke, Lucas is also related to international name star Luca, while the similar Lucius and Lucian derive from a different root and have a different meaning.
 Lucas is enjoying tremendous international success, popular throughout the English-speaking world as well as in a diverse range of countries throughout Europe and Latin America, including Scandinavia, France, Germany, Spain, and Brazil. This makes Lucas the perfect choice for a cross-cultural family.
 Lucas has long been a favorite of TV scriptwriters, from the early black-and-white days of The Rifleman (Chuck Connors as Lucas McCain) to the schoolteacher series Lucas Tanner to the more contemporary One Tree Hill. On the literary side, the name appears as Lucas Beauchamp in William Faulkner's Intruder in the Dust and Light in August.
 Lucas Cranach was an important German Renaissance painter and printmaker; Lucas Samaras is an eccentric Greek-born American contemporary artist. Some will associate the name with director George Lucas.

Lucas

Luis has long been one of the most popular Hispanic names in America — it was in the Top 100 every year from 1980 to 2014, though it's dropped a bit in popularity. It's familiar, yet would add a worldly touch to a basic surname. 
 Luis has many notable namesakes, from film director Luis Bunuel to baseball Hall of Famer Luis Aparicio.

Antônio

Popular among Hispanic communities but also used internationally, Manuel is a name with a regal history. 
 
In use since the 13th century, Manuel was likely brought to Spain and Portugal from the Byzantine Empire thanks to connections between their royal families. Borne by two Byzantine emperors and two Portuguese kings, Manuel has been used fairly consistently throughout history and into the present.

In the US, Manuel has been a staple feature in the Top 1000 since the data began to be collected in the late 19th century. Until recently, this Spanish variant had always outranked its English counterpart, but since the mid 2000s, Manuel has been in decline while Emmanuel has been on the rise.

Still in the Top 500, but at its lowest ever rank, Manuel is currently given to around 1000 boys each year in the States.
 
Across the globe, Manuel has fared better. It remains well used in Spain, Portugal and Italy, across South America, and in The Netherlands and Germany too.

Manny and Manu are popular nickname options, with Manu gaining traction as a stand-alone choice in The Netherlands.

Manuel

Both the Spanish Marcelo and Italian Marcello would work well for children of any backgrounds. 

Marcelo

Another culture's slant on Mark, sometimes associated with former president of the Philippines Ferdinand Marcos and his shoe-collecting wife, Imelda. 

Marcos

Mike Tyson put a twist on his own name by naming a son Miguel. It's the first name of Cervantes, the great Spanish novelist and poet who wrote Don Quixote.

Miguel has always charted in the US, but peaked in the 80s and 90s along with other classic Hispanic names such as Jesus, Luis, and Jorge.

Older Gen Zs may know of the popular PBS kids show from the early 2000s, Maya and Miguel, while kids today have the adorable, guitar-playing Miguel from the sensational Pixar film Coco.

Miguel

Matheus

Nicolas is the French and Spanish form, or streamlined spelling, of Nicholas, popularized by actor Nicolas Cage. Nicolas has been consistently on the charts since Social Security began releasing data, but the name did not truly take off until around the 70s. Today Nicolas is popular among Spanish and Portuguese-speaking parents, ranking in the Top 30 in Spain, Brazil, and Chile.

Nicolas

Pedro is one of the most familiar <a href="https://nameberry.com/baby-names/496/spanish-names-for-boys">Spanish names for boys</a>, via baseball star Pedro Rodriguez and many others. 

Like its Anglo equivalent Peter, Pedro is not as popular as it once was. But it's among the elite group of boys' names that has ALWAYS ranked among the US Top 1000.

That final O sound, so fashionable today, gives this name an extra spin of style.

Pedro

Energetic, sunny, and slightly romantic, Rafael is a popular choice in Germany, Spain, Portugal, and Croatia. Used internationally, Rafael is a Spanish variation of Raphael, that lends itself easily to the nicknames Rafi, Rafa and Rafe.
 
Derived from a Biblical, Hebrew name, meaning "God has healed", Rafael is associated with both an archangel in The Old Testament and with the master Renaissance artist.
 
With its lighter, more concise appearance and Its hint of flair and fun, the Rafael spelling is perhaps most famously borne by tennis play, Rafael Nadal. 
 
Popular but not too popular in multiple different countries around the world, Rafael sits in the Top 100 in Mexico, Switzerland, Chile, and Uruguay,.
 
In the UK, it climbed to #181 in 2022 (though Rafferty and Raphael still outrank it), while in the US, it has been the favored spelling since the 1920s.
 Given to 1500 babies in the US each year, Rafael fits in with currently trending choices like Jaziel and Azriel, while still feeling perfectly familiar.

Rafael

Rhythmically appealing international spin on the stiff original.

Some high-profile soccer stars, such as Thiago Silva, have contributed to its success. The correct Portuguese pronunciation is chee-AH-go. Thiago is ranked Number 2 for boys in Puerto Rico.

Vitor

Common Russian name familiarized here via cosmonaut Yury Gagarin and a character in Dr. Zhivago, but we don't see it ever gaining permanent resident status.

Gregório

The classic Jorge is one of the most popular and classic <a href="https://nameberry.com/baby-names/496/spanish-names-for-boys">Spanish names for boys</a> in the US. Some Latine families pronounce it the same way as George.

Jorge

The related Lucas and Luke are both hugely popular boy names in the US and internationally, and now Luca has joined them on boys' popularity lists around the world.

That's an astonishing success story for a name that was virtually unknown a generation ago. Only 13 baby boys were named Luca in the US in 1980, and by 1990 it was still only 32. But by the turn of the century, Luca took off and has now surpassed his more familiar brother Luke in the US.

Boy names ending in vowel sounds may have felt too feminine to early generations who lived by more conventional gender rules. And that old school he-man America also may have rejected names like Luca for being too "foreign". But in this era of Noah and Mateo, Elijah and Ezra, Luca has finally found widespread acceptance.
Along with its popularity in the US, Luca ranks highly in a range of countries that speak English, Spanish, French, and German, among others. While Luca is technically related to Luke and Lucas and so takes their ancient Roman habitational meaning, you might also see it as a relative of Lucius or Lucian, meaning light.
 Colin Firth and his Italian wife chose Luca for one of their sons, as did Hilary Duff, Vincent d'Onofrio, Rebecca Minkoff, and Jacinda Barrett and Gabriel Macht.

Maurilo

Beort12's list "Brazilian Names - Boys" of 37 great name ideas: Adriano - Maurilo!

Brazilian Names - Boys

Brazilian names are general very traditional, but often Brazilians will have (and use) more than one first name. Nicknames are also VERY common, although they are generally not consistent - you can call within a day the same person by several diminutives. Here I have stuck to traditional names and traditional spelling, although, like anywhere, Brazilians like to mess with spelling to make their names more "unique".
