Dog Names That Start With J

Although Joan was the more popular name in the 20th century, it's the nickname Joanie that is coming back in style, in tune with the likes of Bonnie, Margot, and Billie, or Sadie, Elsie, and Libby. A Top 1000 name back in the 1950s and 60s in the US, in England and Wales,, it re-entered the the charts in 2025.
 
Alternative spelling Joni (made popular by the singer) was always more popular, and remains so in England and Wales where its ranked since the 2010s.

The New Jersey cities of Camden and Trenton are in, but the name of the state has not caught on to anywhere near the same extent, possibly due to its association with knitted pullovers and reality TV. Nevertheless, Jersey peaked as a masculine name in 2022, when it was given to around 60 boys.
 
The etymology of Jersey is not certain, but it may derive from the Norse name Geirr which means "spear", with the suffix -ey meaning "island". Alternative theories suggest it comes from jarl , meaning "earl" or hjǫr meaning "sword".
 
YouTube family and social media stars The Mighty McClures named their son Jersey in 2017, who joined old twin sisters Ava and Alexis.

Jori is a feminine name with multiple cultural origins. In Finnish, it's a variant of Jorma or Jorge, while in Hebrew it can be a feminine form of Jory or a variant of Yori, meaning 'he teaches.' It can also be considered a shortened form of names like Marjorie or a variant of Jorie. This short, crisp name carries a modern, minimalist appeal with its simple four-letter structure. Jori has maintained modest usage in the United States and Europe, appealing to parents who prefer concise names with cross-cultural appeal. The name's brevity makes it both memorable and easy to pronounce across different languages.

Janet started as a pet form of Jane but has long been used independently. Jane is a feminine form of John, which derived from the Hebrew name Yochanan. Janet can also be considered a variation of Jeannette, a derivative of Joan and another feminization of the name John.
 
Five hundred years ago Janet was a royal favorite in Scotland, where it remains a common name. Here in the US, however, Janet has been on a downhill slide since the 1960s, with Grandma Janet now knitting booties for baby Janae. Or even, increasingly, Jane.
 There have been several Janets recently involved in US government, Janet is a leading member of the Jackson family, and Janet Evanovich is a bestselling author; and in the past there have been first Best Actress Oscar winner Gaynor, Psycho actor Janet Leigh, and the mother of Jackie Kennedy.
 There are several attractive foreign versions that might prove appealing alternate namesakes for Gran Jan—Gianetta, Zaneta, Janneth, Sinead or Janica.

Janet

Pronounced as the English word joy, rather than as the French phrase joie de vivre, Joie might produce more complications than joy.

Jarvis, one of the original two-syllable nouveau boys' choices, is a saint's name with a certain retro charm and a nice quirky feel. Though Jarvis peaked in the late 1880s, he is beginning to sound fresh again.
 Jarvis Lorry is a character in Dickens's A Tale of Two Cities, and there was another Jarvis in Upton Sinclair's The Jungle. Probably the best known modern Jarvis is British rocker Jarvis Cocker.

James for a girl? Believe it or not, this is one of the <a href="https://nameberry.com/list/79/boy-names-for-girls">boy names for girls"</a> gaining a lot of attention these days, since Blake Lively and Ryan Reynolds shocked the world by choosing it for their eldest daughter in 2014 (after his late father).
 
Since then, it's become something of a celebrity baby middle name du jour, with high-profile parents including Coco Rocha, Kristin Cavallari, Nev Schulman and Brandon Jenner all having daughters with James in the middle spot.

James

Peaked in the 1940s, but still an amiable classic, a la Joe and Tom -- though rarely used on its own. 

Juna, a variation of the newly stylish month name June, goddess name Juno, or literary Djuna, is among the fresher-feeling <a href="https://nameberry.com/search/girls-names/j">girl names starting with J</a>. While Juna has never been given to more than 50 baby girls per year in the US, it's a popular choice in Germany, Switzerland and the Netherlands.

Jupiter's partner Juno has entered the mainstream, so it's possible that her divine mate could follow. But not necessarily for boys — Jupiter is currently mostly female in the US, thanks to its similarity to Juniper. Stars including Ed Sheeran and Ashley Tisdale recently welcomed daughters named Jupiter, which could shift the balance even more towards the girls.

The name of the supreme Roman deity and the largest planet has until recently had either too hippie or too grandiose a feel for most mortals, but with the rise of sound-alike Juniper and space names such as Orion and Mars, Jupiter may find new favor.

Short form Jupe is adorable.

More background on that deity: Jupiter was the king of the Roman gods, and god of the sky, the equivalent of Greek Zeus. His name may have originated as a title. It can be interpreted to mean "father of the sky" or "father of the gods" (dyew-peter > iou piter > iuppiter (the form of the name used in Latin) > Jupiter). With Juno and Minerva, he made the Capitoline triad, whose worship was at the very centre of Roman religion.

Jeter, which of course is used as a first name only because of Yankee star Derek, rhymes with Peter and may be derived from the French surname Jette, which was often bestowed on foundlings because it means "thrown out," or the German Jetter, an occupational name meaning "weeder".
 
These days, however, it may also be seen as a creative spin on Jet or Jett, blended with the popular -er ending, which also links it to jet engines, jumbo jets, the shade jet black, and to the gemstone.

Jeter

Jazz as a full name is used slightly more often for boys than girls and has a distinctive, well, jazzy feel.  Jazz is also occasionally used as a nickname for Jasper, much more often for Jasmine or Jazlyn. Could work as a middle name.

Jeff

Jonny is a masculine name primarily functioning as a diminutive or informal version of Jonathan, which derives from the Hebrew name "Yehonatan" meaning "gift of Jehovah" or "God has given." Jonny offers a friendlier, more approachable alternative to the more formal Jonathan. While sometimes used as a standalone name on birth certificates, it's more commonly a nickname. The spelling with two 'n's distinguishes it slightly from the variation Johnny. This name carries a youthful, casual energy and has been moderately popular in English-speaking countries. Jonny has associations with relaxed, down-to-earth personalities and has been used for various characters in popular culture and sports figures.

Jonny

Justine is a French name that's never reached the popularity we think it deserves. Like its far-more-common brother Justin, Justine is sleek, and sophisticated, but still user-friendly. 
 Justine has had a very erratic popularity path in this country. It first was noticed in the late 1950's via the eponymous novel that was part of Lawrence Durrell's Alexandria Quarter, but reached its highest peak--at Number 175-- in the eighties, during the TV run of Family Ties, featuring Justine Bateman. Justine is still a Top 60 name in its native France.

Justine

Juniper is a nature name that we really like. While it's trendiest for girls -- about 2500 baby girls were named Juniper in 2022 versus 34 baby boys -- the most notable Juniper in history was the saint Brother Juniper, a follower of Saint Francis renowned for his generosity.  Blessed Junipero Serra, who founded the first of the California Missions, took his name from the earlier Saint Juniper.

Juniper

A son of Noah in the Bible who is also thought to be an ancestor of the Greek people and the guardian angel of Greece. An alternative to Jason or Jayden, perhaps.
