Boy Names Starting with J: Classic James to Rare Justus

Looking for boy names starting with J?

Parents love the letter J. It starts John, Joseph, and James, the most evergreen of classic boy names.

But it’s also the first letter of chart-topping modern inventions, like Jayden and Jaziel. Tally up all of the spellings of Jackson, and it is a powerfully popular choice – by some measures, a former #1 name in the US.

Every style in between is represented, too. Biblical favorites, like Joshua and Jacob, to imports like Javier, word names like Justice, and, of course, the oh-so-cool, but still traditional Jack.

No surprise, then, that J is the most popular letter for boy names in the US.

Read on for more boy names starting with J, from the most popular of the moment, to the rarities you might consider for a son.

POPULAR BOY NAMES STARTING WITH J

JAMES (#4)

A Biblical classic name, worn by saints and kings, as well as many other notables. It’s hard to overstate this name’s classic status. What has changed? Nicknames! An early generation answered to Jimmy and Jim, but more recently James are likely to be Jamie … or, more and more often, just James.

JACK (#14)

The name of action heroes from fairy tales to Hollywood blockbuster, this traditional nickname for John stands on its own nicely.

JOHN (#26)

The long-running top name in the US has fallen from its perch, but remains in steady rotation. Factor in all the John-derived and related names, and it’s clear the name’s influence has not waned.

JACKSON (#28)

A surname name meaning son of Jack, Jackson is associated with artists (Pollock) and presidents (Andrew), and found all over the map.

JOSEPH (#29)

Along with James, one of the most evergreen of boys names. And thanks to nickname Joe, one of the most approachable, too.

JULIAN (#33)

A sophisticated, longer boy name just right for our age of Sebastian, Oliver, and Adrian. The spelling Julien is on the rise, but remains far less common.

JACOB (#36)

Believe it or not, James and Jacob are twins, separated at birth – or maybe shortly thereafter. They’re both ultimately derived from the Hebrew Ya’aqov, which became Iakob, Iacobus, and Iacomus … and eventually, in English, Jacob and James.

JAYDEN (#49)

As the Aidan names surged in popularity, Will and Jada Pinkett Smith named their son Jaden in 1998. By 2003, it was the Jayden spelling that headed towards the US Top Ten. After five years there, it’s fading now, but there are still lots of newborns whose names end in the -aidan sound.

JOSIAH (#51)

An Old Testament name with a long history of use, from the eighteenth century Josiah Bartlett, signer of the Declaration of Independence, to West Wing’s fictional president Josiah “Jed” Bartlet – named after the original.

JOSHUA (#60)

It’s easy to dismiss Joshua as a faded 80s favorite. But Joshua ushered in an entire generation of boy names, from Noah to Sebastian.

JONATHAN (#82)

It looks like a John-Nathan smoosh, but it’s an independent name. Gulliver’s Travels author Jonathan Swift lends it some literary appeal.

JAXON (#86)

A twenty-first century spin on Jackson, possibly intended to make Jax the logical short form.

JEREMIAH (#92)

Jeremy was long the popular form of Jeremiah, but lately it’s the full Old Testament original that appeals to parents – and fits right in with favorites like Elijah and Isaiah.

JOSE (#93)

The Spanish form of the classic Joseph.

JORDAN (#98)

The name of the river where Jesus himself was baptized, Jordan might be a deeply spiritual choice. But it was also a smash hit of the 1990s, helped in part by Jordan Knight, frontman of chart-topping 90s boy band New Kids on the Block.

JAMESON (#103)

A surname name in the key of Jackson.

JACE (#110)

A twenty-first century take on 70s favorite Jason.

JASPER (#122)

The masculine answer to Ruby and Pearl.

JONAH (#124)

Bright and energetic Jonah comes with a built-in whale of a (Biblical) tale, but this Old Testament name is broadly popular.

JAXSON (#138)

Another possible Jackson/Jaxon spelling.

JUAN (#141)

The Spanish form of John, every bit as classic.

JASON (#147)

A Top Ten name from 1971 through 1983, Jason has faded slowly. In Greek myth, Jason led the Argonauts and searched for the Golden Fleece. If it hadn’t been so big back in the late twentieth century, it would be a smash hit today, thanks to ancient roots and a cool, modern sound.

JUDE (#161)

A short and strong sound, Jude is familiar to the world thanks to the Beatles’ “Hey Jude.”

JAYCE (#166)

Another possible spelling for Jace.

JESUS (#172)

Another traditional name for Spanish-speakers, seldom heard as a given name in English.

JUDAH (#176)

An Old Testament name, Judah is a longer form of Jude – or simply a slightly different alternative.

JUSTIN (#185)

A former favorite with ancient roots, Justin brings to mind 90s boy bands. But this name has actually appeared in the US Top 1000 every year since before 1900, so Justin has staying power.

JESSE (#203)

A former favorite, Jesse feels more classic than dated. Another bonus? The meaning: gift.

JETT (#206)

A high-flying, energetic name for a son.

JOEL (#212)

An Old Testament name, Joel lags behind Joseph and now Jonah, too. But it has plenty of appeal.

JAVIER (#239)

The Spanish form of Xavier, boosted by leading man Javier Bardem, along with other notables.

JEREMY (#245)

A 1970s and 80s favorite, Jeremy is the typical English version of the Old Testament Jeremiah.

JAYLEN (#270)

Several talented athletes answer to this Jayden-inspired spin-off.

JORGE (#276)

George translated into Spanish, pronounced with two syllables.

JAX (#287)

Jack meets Max.

JOSUE (#294)

Joshua in translation.

JENSEN (#301)

A generation of Jennifers might inspire sons named Jensen in their honor; or perhaps this Scandi surname related to John is yet another Jackson-inspired possibility.

JAZIEL (#311)

It sounds angelic – thank Raphael, Gabriel, Castiel. And Jahzeel is an Old Testament figure, though this spelling feels modern.

JOAQUIN (#335)

A Spanish classic, Joaquin is far more familiar than Joachim, said to be the father of the Virgin Mary.

JARED (#345)

A name mentioned in the Old Testament, Jared means descendant.

JADEN (#352)

Another spelling of former favorite Jayden. This is the one Will Smith and Jada Pinkett used for their son, inspired by mom’s name.

JAY (#382)

Short for nearly any J name on this list, or a stand-alone.

JULIUS (#400)

An ancient name, the original form of Julian and all the other Jul- names we know so well.

JAKE (#407)

More casual than Jacob, not quite as popular as Jack.

JALEN (#431)

Jaylen, hold the Y.

JOHNNY (#436)

A casual take on John.

JOHNATHAN (#467)

Jonathan, add the H.

JEFFREY (#485)

A former favorite, Jeffrey would’ve been Geoffrey in the Middle Ages – think Chaucer – but today is all dad-name … and almost always spelled with a J.

JAIDEN (#502)

Another logical spelling for Jayden.

JASIAH (#504)

Josiah meets Jase.

JAMIR (#525)

A take on Jamar, one of several invented names in long use with similar sounds.

JONAS (#532)

A smooth take on Biblical Jonah, favored in northern Europe. It’s also the surname of the musical Jonas Brothers.

JAXTON (#535)

Take Jack and Max, combine, and then layer in favorites like Braxton to arrive at this new possibility.

JOHAN (#564)

An older form of John, still heard in Scandinavia.

JAMARI (#566)

Boy names ending with -amari are a white hot trendlet, so no surprise Jamari makes the list.

JULIO (#574)

The Spanish form of Julius.

JAIME (#584)

Another cousin to James.

JAYSON (#589)

One more spelling for Jason, likely influenced by Jayden.

JAMIE (#597)

Once upon a time, every James became Jim. Now they’re more likely to be Jamie – if they use a nickname at all, which is no longer automatic. And just like Charlie, Jamie also stands alone.

JAYCEON (#598)

The rapper known as The Game started out life as Jayceon Taylor. His name rushed up the popularity charts after he and his fiance debuted their VH1 reality series, Marrying the Game. With the series ended, this spelling is falling in use.

JASE (#613)

Another Jason/Chase mash-up.

JULIEN (#635)

Julian with an E is favored in France; rare most other places.

Fast-rising J name, and cousin to choices like Dakari, Jabari, and Jamari.

JAKAI (#730)

Zakai, Makai, and, of course, Jakai.

JIRAIYA (#735)

Borrowed from a traditional Japanese folk tale, Jiraiya found a fresh audience thanks to manga and anime series Naruto. He’s a ninja and a toad sage in the new stories, playing on parts of the original tale.

JUNIOR (#736)

Sometimes a nickname for a boy named for his dad – think James Smith Jr. – Junior has a long history of use as a given name, too.

JEFFERSON (#762)

A surname name that owes something to Jameson, and maybe a little more to Hamilton.

JAHMIR (#809)

Jamir with an extra H.

JIMMY (#818)

A go-to nickname for James, sometimes given independently.

JAXXON (#846)

Jackson turned up to eleven.

JIREH (#848)

fix

JERRY (#850)

An early 1940s favorite, sometimes short for Gerald, Jeremy, or another Jer- name, Jerry has fallen from its Top 20 peak. But just like so many midcentury names, Jerry will (eventually) return.

JAGGER (#854)

A rock star surname name with swagger to spare.

JUDSON (#859)

Back in the day, Jordan shortened to Jud. Give our love of Jackson and Hudson, Judson feels quite current.

Another take on Josiah.

RARE BOY NAMES STARTING WITH J

JAD

A name with Arabic roots and a weighty meaning: serious.

JAI

In Sanskrit, Jaya means victory. Jay reads masculine in US, but spelling it Jai emphasizes Indian heritage.

JAIR

Cousin to Jairo. Jairus is another possibility.

JACOBY

Jacboy – a surname based on Jacob – has previously ranked in the US Top 1000, a cousin to the more-popular Zachary and Jeremy.

JACQUES

The French form of James, though it’s a little closer to Jack in American English. Jacqueline has been popular among girls names in the past, while Jacques remains under-the-radar in the US.

JAGO

A Cornish form of Jacob, more familiar in the UK than the US.

JAKOBE

Another spelling of Jacoby, this spelling influenced by the late Kobe Bryant.

JAMAL

An Arabic name meaning handsome.

JAPHETH

One of Noah’s three sons in the Old Testament.

JARETH

A Jared-Gareth mash-up invented for David Bowie’s role as the Goblin King in 1986’s Labyrinth. 

JARON

With Hebrew roots, Jaron might appeal to parents looking for something slightly different, but with meaning.

JARRETT

Another Jared-Garrett cousin.

JARVIS

If you know your Avengers, Jarvis is Iron Man’s AI butler. But long before that, Jarvis was an English version of the Germanic Gervais, meaning spear.

JAVAN

In the Old Testament, Javan is Noah’s grandson, and ancestor of the Greeks.

JAXTYN

An even more creative take on Jaxton.

JEAN

The French form of John, often used in combination: think Jean-Claude, Jean-Jacques.

JEB

A down-to-earth nickname name.

JED

Just like Jeb, but swap the B for a D.

JEDI

As in Star Wars. If we name our kiddos Anakin and Kylo, why not the heroic Jedi, too?

JELANI

Embraced by African American parents, Jelani appears to have Arabic roots. It rose originally thanks to a basketball player in the late 1990s. A more current influence might be author and journalist Jelani Cobb.

JENNINGS

A surname name related to John, Jennings peaked in the late nineteenth and early twentieth centuries. That tracks with the career of populist politician William Jennings Bryan. Today it feels like an unexpected surname name.

JEROME

Yes, Jerome. This traditional and long-used name no longer charts in the US Top 1000.

JETHRO

An Old Testament name meaning abundance, Jethro could be a cool o-ending boy name. Two possible roadblocks: classic rock band Jethro Tull, named for an eighteenth century agriculturalist, and The Beverly Hillbillies character. A far more recent reference? NCIS’s Jethro Gibbs, though he’s nearly always called by his last name on the long-running series.

JETSON

Jett meets the popular -son ending.

JIRO

Japanese name meaning “second son,” made familiar in the US thanks to 2011 film Jiro Dreams of Sushi.

JODY

Probably originally short for Joseph, Jody became a sensation for boys thanks to 1938 bestseller The Yearling, a Pulitzer Prize-winning novel, as well as the 1946 film adaptation. It became a true unisex favorite, peaking for girls and boys alike around 1970.

JOLYON

An older form of Julian, made familar thanks to the early twentieth century novels The Forsyte Saga, by John Galsworthy.

JORY

It could be short for Jordan, but in Cornish, Jory is the equivalent of George.

JOTHAM

Another Old Testament rarity, Jotham appears twice – as a King of Judah, as well as one of Gideon’s sons. It’s made more wearable by easy nickname Joe.

JOVE

Another name for Jupiter, king of the gods in Roman mythology.

JUBAL

A rarity from the Old Testament with an appealing backstory: he’s the first person to become a musician.

JUDD

Originally short for Jordan, Judd now feels more like a Jeb/Jed and Jude cousin.

JUELZ

Traditional Jules respelled, thanks to musician Juelz Santana.

JULES

With Julian in the Top 100 and Julien rising fast, why not Jules? It’s the French form of Julius, made literary by trailblazing author Jules Verne.

JUNOT

The masculine equivalent of goddess name Juno, made familiar by writer Junot Diaz.

JUPITER

As in the Roman god, and the planet, too.

JUSTUS

A Latin name meaning just, Justus looks like word name Justice, but has centuries of use behind it.
