Quirky cool Arlo is now well and truly back. Last year it broke into the US Top 200 boy names and consistently ranks among the most popular boy names on Nameberry. 
 Arlo is even more popular in the UK, Australia and New Zealand. Arlo is also one of the top baby names among Nameberry's visitors from leading US cities.

 
Once strongly associated with shaggy singer Arlo Guthrie, Arlo has an animated and cheery feel, thanks to its upbeat o ending. It was chosen by Toni Colette for her son in 2011, which brought the name back into the spotlight. Previously, Arlo was in regular use in the first half of the twentieth century—it was Number 667 in 1915, for example, but it had dropped off the charts in 1944.
 Arlo has many possible derivations along with its Irish and English roots. It may be a shortened form of the Italian name Carlo or the Spanish Carlos, and in Basque-speaking regions it is the word for area. In English, Arlo was used as a place name, Arlo Hill, by Edmund Spenser in his epic poem The Faerie Queene and is thought to derive from the Celtic word Aherlow, meaning "between two highlands."

 A growing number of girls are also named Arlo in the US each year, with a handful more babies of both sexes receiving the Arlow and Arlowe spellings, which take this name more into smart surname territory.

Arlo

The popular single-named alternative singer (born Bek) has given this cool nature-meets-surname name a new lease of life. Another notable bearer is Beck Weathers, a Texan pathologist who survived the 1996 Mount Everest disaster, which was covered in the book and film Into Thin Air.

 Outdoorsy yet refined, Beck still sits below the radar but could follow brother Beckett up the charts.

Beck

Bennett is Ben with a bow tie, kind of a cross between Benjamin and Beckett. It's been trending up on the popularity charts in recent years, and its choice by The Unbreakable Kimmy Schmidt's Jane Krakowski could shoot it even higher. 
 Bennett Cerf was an eminent publisher--one of the founders of Random House--and renowned punster.
 Bennett is a popular surname, and has many noteworthy bearers, from Jane Austen's Pride and Prejudice family (with one 't') to indomitable singer Tony. Bennett has been used as a surname in England since the early thirteenth century.

Artistic associations with the sculptor who invented the mobile make this one of the more creative surname choices. 

Calder

A simple one-syllable name that has been on the popularity list since the mid-1980s, Drake is most associated today with the single-named rapper (born Aubrey). The name peaked at Number 197 in 2010 and has since been on a slow decline, but it still can be counted among the stylish contemporary <a href="https://nameberry.com/search/boys-names/d">boy names starting with D</a>.

Eliot

One-time beach-boy compadre of Glenn, Greg, and Gary that originated as a nickname for a tall person, Grant has become a no-nonsense, career-oriented grown-up and one that is seeing new appreciation.  It was chosen for his son by actor Morris Chestnut. It has cultural cred via artist Grant Wood, whose best known painting is 'American Gothic.' 

Grant

This name projects a sense of well-being - hale and hearty - is unusual but accessible, with a clear simple sound, and a worthy namesake, Revolutionary War hero Nathan Hale, as an added bonus. 

Hale

Ian is Scottish form of John, derived from the Hebrew name Yohanan. It is an Anglicization of the Scottish Gaelic Iain, which is also a viable spelling. Ian was introduced to Americans by Ian Fleming, creator of James Bond.
 
Ian has enjoyed remarkable longevity, ranking in the Top 100 since the early 1980s but never vaulting into the Top 50. That's packing a lot of power into three letters.
 
Notable namesakes include actor Ian McKellan and novelist Ian McEwan. Actor Ian Ziering pronounces his name EYE-an, rather than the traditional EE-an.

Jack may have fallen from its Number 1 place in England, but in the US it's as popular as it was at its height in the 1920s and 1930s. A durable, cheery, everyman form of John, Jack ranks as one of the most popular <a href="https://nameberry.com/search/boys-names/j">boy names starting with J</a>. 
Jack is a derivative of John that originated in medieval England. The name went from John to Johnkin to Jankin to Jackin to Jack. The name was so common in the Middle Ages that Jack became a generic term for a man. 
 
Jack is familiar to all from earliest childhood via Jack and Jill, Jack Sprat, Jack and the Beanstalk and Little Jack Horner et al. It is still a recent favorite for novel, TV and movie characters. 
 
Jack is at the top of the charts in Ireland and Scotland, and also ranks highly in Germany, Sweden, the Netherlands, and Belgium.
 
The jaunty Scottish version is Jock.

Jack

Jason, the Number 3 name for the entire decade of the 1970s -- thus the title of our original baby-naming book, Beyond Jennifer & Jason -- is more likely to be dad's name now than baby's, but it's still a widely used name. 
 
Jason's megapopularity definitely launched stylish newcomers ranging from Jacob to Mason to Jackson. It's easy to forget, given its trendiness, that Jason is actually one of the classic <a href="https://nameberry.com/baby-names/508/greek-names-for-boys">Greek names for boys</a>.
 In Greek myth, Jason is the leader of the Argonauts who went in search of the Golden Fleece, while in the Bible he was an early Christian who was hospitable to St. Paul.
Jason figures in the novels of William Faulkner, especially in The Sound and the Fury. Famous Jasons include Jason Bateman, Jason Segal, and Jason Kidd.

Jason

Jasper originated as a variation of the Latin Gaspar, which ultimately derived from the Persian word ganzabara, meaning "bringer of treasure." As a given name, Jasper’s etymology is unrelated to that of the gemstone, which comes from a Semitic word meaning "speckled stone." Jasper is the usual English form for one of the Three Wise Men who brought gifts to the infant Christ according to medieval tradition and appears in the Bible as a reference to the stone itself in Revelations 4:3.
 
Jasper has a lot going for it—it's been rocketing up the ranks in the US, after long being considered a posh and charming name in England. Distinctly masculine, Jasper represents a variety of quartz—one of the few gem <a href="https://nameberry.com/boys-names">names for boys</a>—and is the first name of the great modern artist Jasper Johns. Our only caveat: Jasper is a favorite of a lot of hip parents, and has gotten even more popular since its strong appearance in the Twilight books and movies.
 Jasper has considerable literary cred as well, appearing in works by Sir Walter Scott, James Fenimore Cooper, Thackeray, and Thomas Hardy--as well as Stephenie Meyer. 
 Casper/Caspar is the German version.

Jasper

Cowboyish short form that's both macho and cool. Got prime time exposure on The West Wing.

Jude is a modern star, maintaining a steady level of popularity -- but not TOO much popularity, in the US at least. Thank Jude Law and the great Lennon-McCartney song "Hey Jude", double-handedly responsible for propelling Jude up the charts.
 Saint Jude was the apostle who intervened on behalf of people with problems and became the patron saint of lost causes. This positive Biblical association helps to distance the name for the similar Judas, borne by the traitorous Judas Iscariot.
 
A literary name, appearing in Thomas Hardy's tragic novel, Jude the Obscure and in the more recent (but equally tragic) A Little Life by Hanya Yanagihara, Jude is also notably borne by footballer Jude Bellingham. The name is occasionally used for girls (as in Martha Stewart's granddaughter)--but more often as a shortened form of Judith/Judy.
 
Currently a US Top 200 name, in the UK, it entered the Top 20 in 2023.

Jude

Cool and charming, with plenty of flair and sophistication, Julian manages to strike the balance between being a sensible classic and contemporary choice. Appealingly international, it is no wonder Julian is a rising star.
 
The name Julian derived from Iulianus, which in turn came from the Roman family name, Julius. Its origins are hard to pin down, but possible roots include the Latin iuvenis, meaning “youthful”; the Greek ioulos, meaning “downy-bearded”; or Jovis, a form of Jupiter, which means “sky father.”
 
A well-travelled name with plenty of history, Julian, rather fittingly, was the name of St. Julian the Hospitaller, the patron saint of travellers. Other famous Julians include Julian the Apostate, a 4th century Roman emperor, the activist and politician, Julian Bond, the singer and documentary maker, Julian Lennon, and the novelist, Julian Barnes.
 
Beyond the history books, Julian has also made its mark on popular culture. It was used by Shirley Jackson in her mystery novel, We Have Always Lived in The Castle and by Jessica Love in her award-winning picture book Julian is a Mermaid. It has also been given to characters on TV shows such as “Alias”, “Law & Order”, and BBC “Ghosts”.
 
Julian is currently a firm favorite in the US, where it has been given to 7000 boys each year and remained in the Top 50 for the last decade. It’s also made waves in Austria, Sweden, Chile, The Netherlands, and Mexico, where it ranks in the Top 100 of each country.
 
The name holds sway with celebrities too, with Robert De Niro, Lisa Kudrow, Jerry Seinfeld, Paula Patton, Robin Thicke, Daniel Wilcox, and Jennifer Paz among those who’ve chosen it for their sons.
 
Though significantly more popular for boys, in Medieval England, Julian was considered unisex. A handful of girls are still given the name today, though Julia and Juliet are parents’ current preferences.
 
If the handsome, versatile Julian appeals to you, but the popularity holds you back, then you could consider one of its variants, such as Guiliano, Jolyon, Julen, or Jules, or perhaps even Jupiter for something very bold.

Julian

Kai is an internationally flexible name with many possible origins and meanings, growing in popularity in the US and a diverse range of European countries.
 
In the US, the name Kai is most commonly referred to as being of Hawaiian derivation, meaning "sea." In Europe, Kai is largely considered to have Frisian origin as a diminutive of the name Kaimbe, meaning "warrior", or as a short form of Gerard "brave spear". 
 
Kai is also found as an independent name in African, Chinese, Turkish and Native American cultures. Kai is a strong, evocative multi-cultural name that packs a lot of power in its single syllable. 
 
Famous as the name of the boy enchanted by the fairy-tale Snow Queen, Kai was chosen for her son by actress Jennifer Connelly and as a middle name for son Samuel by Naomi Watts and Liev Schreiber. 
 
Kai is popular with Berries as both a first and middle name choice. Perhaps because of its international familiarity, Kai is popular in video games. Its most prominent namesake is Danish-born jazz trombonist Kai Winding.
 
Kai ranks in the US Top 1000 for girls, but is used more than 90 percent of the time for boys. Donald Trump, Jr. has a daughter named Kai Madison and Gigi Hadid and Zayn Malik named their daughter Khai in 2020.

Jasper and its many international variations, from Kasper to Casper to Gaspard, is finding new popularity.

Kasper

Kent is a no-nonsense, brief, brisk one-syllable name, almost as curt as Kurt. 

Kent

A friendly Irish and Persian name chosen by Geena Davis for one of her twin boys, whose father is Iranian.

Irish and Iranian has to be one of the most diverse pair of roots of any name. Kian can be a variation of the Irish Cian, very popular in its native land. While Cian is fairly rare in the US, Kian has been rising through the ranks for the past two decades. The Irish Cian or Kian is pronounced with the emphasis on the first syllable, KEE-en, rhyming with Ian.

The Iranian Kian is pronounced kee-AHN, like the first two syllables of Keanu as in Reeves.

Spelled Kian, the name is popular throughout the English-speaking world as well as in Germany, Sweden, and Switzerland, but it's impossible to say whether the parents choosing it are going for the Irish or Persian version. Some undoubtedly don't care and simply like the name, no matter what its origin.

Kian

Though it sounds like a modern invention, Kiran is a traditional Hindu name from India; chosen for her son by actress Kelli Williams.  Author Kiran Desai is a woman and this name, which bears a resemblance to both the Irish (male) Kieran and the fifties favorite Karen, certainly works as well for a girl.

Kiran

Actor Kit Harington, aka the dreamy Jon Snow on Game of Thrones, has given this nickname-name new style and appeal for boys. Actress Jodie Foster used it for her son. 
Kit is one of those names that is gender-neutral but has a different derivation for boys and girls. For boys, it originated as a short form of Christopher, while for girls, it's an updated diminutive of Katherine.
Kit as a full name is still beneath the Top 1000 for both sexes in the US, but it's getting more popular. In 2022, 166 baby girls and 137 baby boys were named Kit, up from 104 and 129 in 2021.

Levi, lighter and more energetic than most biblical names, with its up vowel ending, combines Old Testament gravitas with the casual flair associated with Levi Strauss jeans. 
 Now it's being rediscovered in a major way—Levi has been shooting up the charts in recent years. Extremely popular in the US, it's also a Top 100 name throughout the English-speaking world as well as in a diverse range of countries from Germany to Brazil.
 
In the Old Testament, Levi was the third son of Leah and Jacob, from whom the priestly tribe of Levites descended; in the New Testament, Levi was Matthew's given name before he became an apostle. It is suspected that Levi derives from the Hebrew word yillaweh, meaning "he will join." 
 Levi received a lot of attention as the sons of Matthew McConaughey, Sheryl Crow and Sara Gilbert.
 In the Thomas Hardy novel Far from the Madding Crowd, Levi Everdene is the father of the heroine.

Levon is a related name.

Levi

Liam is the top boys' name in the US, holding the Number 1 spot for the past seven years and also ranking as one of the most popular boys' names around the western world.
 Liam originated as a short form of Uilliam, the Irish variation of William. William is an English name from Germanic roots that was brought to Ireland when the British fled England following the Norman Conquest. The Irish began using English names, including William, which led to the development of Uilliam and its short form, Liam.
 Internationally, Liam is enjoying great popularity not only in the U.S. and its native Ireland, but in countries as diverse as Italy and Israel, Chile and Croatia. If you're looking for a boys' name that will easily translate across many languages and cultures, you can't do better than Liam.
 Irish-born actor Liam Neeson was instrumental in driving Liam up the charts, as was former Oasis member Liam (born William) Gallagher, and, more recently, One Direction member Liam Payne. Celebrities who have chosen Liam for their sons include Tori Spelling, Calista Flockhart, Rod Stewart, Kevin Costner and Craig Ferguson.
 Jaunty and richly textured, Liam holds solidly to the title of most popular boys' name starting with the letter L.

Liam

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.

Luca

Mason is an occupational surname that ranked among the Top 10 name for boys throughout the 2010s, after its choice as one of the first Kardashian baby names.
Part of its appeal is as a fresher-sounding replacement for dad name Jason. It's also one of the leaders of the Jackson-Hudson-Grayson-Kayson trend.
Along with Kourtney Kardashian and Scott Dissick, Mason was chosen for their sons by several other celebrities, including Cuba Gooding, Jr., Melissa Joan Hart and Kevin Richardson (as well as by Kelsey Grammer for his daughter).
And there were two cute TV werewolves named Mason: Mason Greyback on Wizards of Waverly Place and Mason Lockwood on Vampire Diaries--a far cry from the name's wholesome image.

Mason

Miles, which has a permanent veneer of cool thanks to jazz great Miles Davis, is a confident and polished boys' name that's an American classic. Always ranking in the US Top 1000, it's been drifting up the charts for the past half century but has never been TOO popular.
 
Miles is a favorite of celebrity baby namers, given to their sons by Elisabeth Shue, Mayim Bialik, Larenz Tate, Joan Cusack and Lionel Ritchie. It also makes a great honor name for all the Grandpa Michaels out there.
 Miles was the name of the first translator of the Bible into English--the English monk Miles Coverdale, which is also the name of a character in Hawthorne's The Blithedale Romance. Miles Hendon figures in Mark Twain's The Prince and the Pauper, and Miles was one of the young children in Henry James's The Turn of the Screw. Miles--or Myles--Standish was the leader of the Pilgrim fathers.
 Miles has also been a favorite movie and TV character name from the days of Murphy Brown to 24 and Avatar.

Miles

One of the first generation of surname names, along with Porter and Morgan, Parker's still one of the most appealing and remains firmly in the Top 100 for boys. About three times as many boys as girls get this occupational name. The association with Charlie Parker gives Parker itself a jazzy edge, and it also has a nature-related meaning. Rosie O'Donnell has a son named Parker.

Parker

A strong single-syllable surname with a joyful meaning, Tate is finding a place on more and more birth certificates.
 Former Spice Girl Emma Bunton named her second son Tate Lee.
 Tate also has a cultural vibe via the Tate and Tate Modern museums in London, named for philanthropist Henry Tate. Actor Tate Donovan is a prominent current bearer.

Tate

As Tyler has begun to recede, a number of parents, including the Wayne Gretzkys, have cut straight to the livelier short form. One thing that may be holding the name back is the tarnished legacy of baseball hall of famer Ty Cobb, who gained a reputation for racist and violent behavior.
