Aidan was originally a pet form of the Irish name Aodh (pronounced 'ee'), the name of the old Celtic god of the sun and fire. The name was borne by numerous early Irish saints, one of whom was noted for his kindness and generosity. 
 
Aidan is an appealing Irish saint's name meaning fire that zoomed up the popularity lists, jumping four hundred places in a decade to a peak of 39 in 2013 before slumping down. Though it has been overtaken by variant spelling Aiden, the original Aidan is worth considering before selecting one of its offshoots: Caden, Brayden, et al.
 
Aidan was first introduced into the mainstream American consciousness by actor Aidan Quinn, and was given a definite bounce by the appealing Aidan on Sex and the City. Aidan has many variations, among them, Aiden, Aden, Adan, Aedan, and Ayden.

Aidan

Great Irish middle name choice for Shakespeare lovers. 

Bard

An attractive ancient Irish saint's name that conjures up a beacon of light, this <a href="https://nameberry.com/list/328/irish-baby-names-for-boys">Irish name for boys</a> is well-used in Ireland but rarely heard in the US.

Beacan

Bellamy is emerging as an up-and-coming <a href="https://nameberry.com/girls-names">girls' name</a>, an Irish surname-y riff on the super-popular Bella series of names. While the Bella connection makes Bellamy sound a little trendier and more popular than it really is, we see the name possibly rising through the ranks for both genders in the coming years.

Bellamy

The Irish name given to Miranda Hobbes's son on the dearly departed Sex and the City is a friendly and energetic choice. You well might want to make your son part of the Brady bunch. 
 Brady has been a well used <a href="https://nameberry.com/boys-names">boys' name</a> since the turn-of-the-last-century Diamond Jim Brady days.
 Brady Fuller is a young werewolf in the Twilight" series, but there were more notable Bradys bearing it as a surname, including Civil War photographer Mathew, press secretary James, and quarterback Tom--in addition of course to Mike, Carol, Greg, Marsha, and Jan et al.

Brady

This Irish name of a saint from the Isle of Aran also appears in myth and fantasy fiction, giving it an intriguing, mystical air. 
 Some modern parents are attempting to update the spelling, as in the actor Breckin (middle name Erin) Meyer or the most popular form of the name, Brecken.

Breccan

Cagney is one of the spunkiest Irish surnames around, and could make a lively and fresher successor to the tired Casey.
 James Cagney will be remembered not only for his iconic gangster films, but also for his Academy-Award-winning performance as song-and-dance man George M. Cohan in Yankee Doodle Dandy. Cagney & Lacey was a popular 1980's policewomen drama.

Cagney

An Irish and Welsh form of Catherine, Caitlin was a boom name of the eighties, rocketing from obscurity (Americans first heard it via the wife of doomed poet Dylan Thomas) to the height of popularity in the space of a decade. The original name was gradually eclipsed by its myriad spelling variations -- Katelyn and Kaitlyn both soon topping it on the popularity lists.
 Now, most forms of Caitlin, including this most-authentic one, have started to dip, though there have been thousands of girls named Caitlin -- and Katelyn and Kaitlyn ad infinitum -- every year for the past three decades. So, while Caitlin is certainly one of the loveliest variations of Catherine, it's been overused to the point of semi-retirement, at least in the U.S. Cait might be a short form.
 Actor Breckin Meyer named his daughter Caitlin in 2003. Caitlyn Jenner also brought a renewed fame to the name, though she uses the -lyn variation.

Caitlin

Caoimhe, pronounced (more properly) kwee-va or kee-va, is a pretty and distinctive Gaelic name but one that could well lead to no end of confusion outside the Irish community. Even in its native habitat, it is sometimes spelled Keeva.
 Caoimhe comes from a word with several positive meanings--beautiful, precious, beloved, gentle, and graceful. It's also the name of an Irish saint.
 Caoihme has been very popular in Ireland in recent years.

Caoimhe

Has fallen off its Kathie Lee Gifford inspired peak in the 1990s, but since that notably celebrity baby is now a grownup and out of the limelight, Cassidy may once again reclaim its own Irish charm.

Cassidy

The name of an ancient Irish saint is in the contemporary Irish Top 50. While it's one of the rare <a href="https://nameberry.com/list/328/irish-baby-names-for-boys">Irish names for boys</a> that hasn't immigrated to the U.S., it may follow brothers Aidan and Declan to our shores. The t is not pronounced.

Cathal

Cillian is one of the native Irish names that, along with Aiden and Declan, is becoming an unlikely favorite in contemporary America. The Killian spelling has been more popular in the US, but Cillian's star is rising, perhaps thanks to Irish actor Cillian Murphy, star of Oppenheimer and Peaky Blinders.
 There are several Saint Cillians, including one who was sent to Bavaria to convert the natives and was martyred for his trouble. 
 Patrick Woulfe, a Catholic priest who was instrumental in reviving native Irish names in that country after the war for independence from England in the 1920s, theorized that Cillian might also be related to a Gaelic name meaning war.

Cillian

Thanks to its dashing Anglo-Irish image — due partly to Colins Firth and Farrell — and its C-initialed two-syllable sound, Colin and its cousin Collin have enjoyed a long run of popularity, reaching as high as Number 84 in 2004. 
 The usual pronunciation of Colin is COLL-in, but the alternate COLE-in version was publicized by General Colin Powell, the first U.S. African-American Secretary of State, who was named after World War II hero Colin Kelly.
 Literary cred: Colin Craven is a character in The Secret Garden, and Colin Creevey appears in the Harry Potter books.
 Both Kevin James and Kiss's Paul Stanley have young sons named Colin, while Tom Hanks has a grown one.

Colin

Midcentury Irish-American favorite, never used in Ireland itself, being the generic word for "girl"; rarely given today. 

Colleen

Connor, the appealing name of an early semi-legendary king of Ulster in Irish mythology, sits firmly in the Top 100 and taken together with its alternate spellings would rank even higher. In its native Ireland the Conor version is one of the highest charting <a href="https://nameberry.com/boys-names">boys’ name</a>.
 Connor MacLeod was the name of the title character in the 1986 film The Highlander, which helped promote the name.
 Nicole Kidman and Tom Cruise have a teen-aged son named Connor, while Eric Clapton has a younger Conor; the name of the Irish writer and historian is spelled Conor Cruise O'Brien.
 Since Connor means 'lover of hounds,' it might make a good choice for a dog-loving family. In fact, one of the sons in Marley and Me is given that name.

Connor

Former teen idol name, now middle-aged. This name has been on a steady decline since the early-1990s.

Corey

Both offbeat and upbeat, this evocative traditional Irish name that runs through Celtic mythology is known here via award-winning novelist Cormac McCarthy (born Charles). The author's adopted name is related to Cormac Mac Airt, one of the great legendary high kings of Ireland.
 In two of the Harry Potter movies, Cormac McLaggen is a Gryffindor student.
 And for all you popularity-phobes, Cormac has never yet made it onto the American Top 1000 list.

Cormac

Declan is the Anglicized form of the Irish name Deaglán. St. Declan was one of the first missionaries to bring Christianity to Ireland, preceding St. Patrick. Originally from Wales, he founded the monastery of Ardmore in Ireland.
 
Declan, the amiable and appealing name of an Irish saint (and the real first name of singer Elvis Costello), is very popular in the Emerald Isle and beginning its certain climb to popularity here, after debuting on the American list in 1998. Like Aidan and Liam, Declan is shaping up to be an American hit.
 
Declan Porter is a current character on Revenge. 
 Cyndi Lauper spelled her son's name Declyn.

Declan

Eamon is one of the traditional <a href="https://nameberry.com/baby-names/168/irish-names">Irish names</a> that has not yet emigrated to the US. This Irish name pronounced ay-mon was popularized by early president of the independent republic Eamon de Valera (birth name George), who was born in the United States to an Irish mother and a Cuban father. Eamon definitely has possibilities as a successor to the epidemically popular Aidan/Aiden.
 Though it may be an older generation name in Ireland, it would sound fresh elsewhere.
 The original spelling of the name is Eamonn.

Eamon

The Scottish Eileen was a midcentury darling that was on a long downward slide for decades. And then, in 2012, it took an unexpected pivot and has been inching upward in the US.

The unrelated but similar-sounding Isla may have revived the taste for Eileen. Isla along with Lee and Lena might be nicknames for Eileen.

Eileen is an Anglicized form of the Gaelic Eibhlin or Aibhilin, which is technically a form of to Evelyn/Aveline, but is also sometimes considered part of the Helen family of names. Aileen is the Irish version, less popular now than Eileen.

Eileen

An appealing Irish placename with a unisex feel, Ennis would be a fresh alternative to Dennis and Ellis. It's little-used for boys and even rarer for girls, but since Kirsten Dunst and Jesse Plemons used it for their son, it could be one to watch.

Ennis

Fallon is one of several boyish surname names introduced in the over-the-top 1980s nighttime soap Dynasty: they sounded cutting-edge at the time, but no longer.

Fallon

This lilting Irish saint's name shone in neon lights on Broadway for the classical 1947 musical "Finian's Rainbow," later made into a film starring Fred Astaire as Finian McLonergan, and there was also a character on 
"General Hospital" named Finian O'Toole. With the growing popularity of Finn and Finlay/Finley--and boys' names ending in 'an'--Finian, which can also be spelled Finnian, seems like a sure-fire winner. 
 One of several early St. Finnians was a noted teacher and scholar.

Finian

Finola, the readily accessible version of some of the more problematic Gaelic versions of the name, would make a welcome addition to the stockpot of Irish girls' names. 

Finola

Flynn, a charming Irish surname, is still used only quietly, despite its easygoing, casual cowboy charm, unlike Finn which is a star of this genre. Flynn was the choice of Orlando Bloom and Miranda Kerr for their baby boy, and is also the middle name -- used as his first -- of a son of Miranda's fellow supermodel Elle Macpherson, of Gary Oldman's son Gulliver and Marley Shelton's daughter West.
 Flynn Rider (born Eugene Fitzherbert) is the dashing animated hero of the Disney film "Tangled." On TV's "Breaking Bad", Flynn was what young Walter Jr. tried to rename himself. The name was long associated with the swashbuckling Errol Flynn, inspiration of the phrase "in like Flynn." Some may connect this name to controversial former National Security Adviser Michael Flynn
 Flynn entered the U.S. Top 1000 in 2011, and is a highly popular choice in Australia and New Zealand.

Flynn

The name of a historic Irish leader, Gannon has a solid, yet spirited feel. It was one of the fastest-rising names of 2014, but that trend didn't continue. One pop culture influence was the name of Teen Mom 3 son Gannon Dewayne McKee.

Gannon

After being one of the hot upscale surnames of the nineties, Garrett has left the Top 100 and this streamlined spelling is dawdling near the bottom of the Top 1000. 

Garret

Take away the Mac and what do you have? Rather than "son of Kenneth," the meaning becomes simply Kenneth, which in itself means son of fire or handsome.

In the US, the name Kenzie peaked for girls about ten years ago. There are still plenty of baby girls named Kenzie, though: More than 500, versus only nine baby boys.
 
Mackenzie peaked earlier, around the turn of the century, but seems to have more staying power. It still ranks among the Top 200 names for baby girls in the US, used for more than 2000 baby girls last year.

Kenzie

Long popular in Ireland and England, Kieran, the name of Ireland's first-born saint and twenty-five other saints, has been building its U.S. fan base thanks to its strong and attractive sound, and its fashionable Irish brogue. While Ciaran is the more authentic Irish spelling, Kieran is more popular this side of the Atlantic. 
 Julianna Margulies chose Kieran for her son, and Kieran is a Culkin brother to Macaulay and Rory. Kier is an attractive short form, and Kiera/Keira is Kieran's girl twin.

Kieran

The additional syllable makes Lark a masculine surname name. 

Larkin

Liam is the top boys' name in the US, holding the Number 1 spot for the past five 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

Lorcan is a name rich in Irish history as belonging to several kings, including the grandfather of the most famous high king of Ireland, Brian Boru. Lorcan O'Toole, known in English as Laurence O'Toole, is the patron saint of Dublin, so it's not too surprising that Irish-born actor Peter O'Toole named his son Lorcan.
 In the Harry Potter epic, Lorcan is the twin son of Luna Lovegood Scamander.
 Strong, easy to pronounce and spell, Lorcan is an Irish name that would stand out from the more common crop of Connors and Liams.

Lorcan

An unusual, energetic surname choice that would make a good Madison alternative. Madigan was a typical police detective series of the 1970s, starring Richard Widmark.

Madigan

Maeve is a short and sweet name that has become one of the most stylish Irish names for girls in the modern US. Maeve would make an excellent first or middle name choice, with more heft than Mae/May and more modern charm than Mavis. 
 Maeve appears in Irish mythology in two forms, one as the powerful Queen of Connacht, the other as the queen of the fairies. Maeve of Connacht was a warrior queen, famous for starting a war in attempt to steal her ex-husband’s stud bull. Other spellings are Meabh, Medb and Meadhbh, which are connected to mead, a honey-based wine that was produced in many ancient cultures.
 
Chris O'Donnell, Lili Taylor and Kathryn Erbe used Maeve for their daughters. The Irish author Maeve Binchy also is a well-known bearer. Maeve is the name of one of the lead characters on the HBO show Westworld.
 Irish spelling Meabh is popular in Ireland, but not recommended in the US.

Maeve

The friendly and sporty feeling Nolan blends some of the best qualities of other popular boy names. With the gentle but energetic sounds of Noah, a hint of the classic Nicholas, and the cool, surname-style vibe of Greyson or Colton, it makes for a familiar and grounded choice. 
Popularized by the baseball player, Nolan Ryan, Nolan has been steadily climbing up the charts since the 1970s, and it entered the US Top 100 in 2011. While it has never been a Top 50 name, it is given to a substantial 5000 babies every year. 
Nolan is the Anglicized form of the Irish name Nuallán, meaning “noble and famous” or “champion.” 
This could give you the fun option of nickname Champ, while also providing the name with weight and history: the O’Nolans were once a chiefly Irish family, descended from the first Celts to settle in Ireland. 
A once very American feeling choice, Nolan is now more popular in France and Canada. It is on the rise in England and Wales too, a favorite in The Netherlands and Belgium, and at #22 in Hungary (albeit with the Hungarian spelling, Nolen). 
Notable Nolans include the fashion designer, Nolan Miller; the Modern Family actor, Nolan Gould; Marvel and DC voice actor, Nolan North; and the actor and singer Nolan Gerard Funk of Glee fame. Some may associate it with the Nolan Chart, a political spectrum diagram invented in the 60’s, while others may be more familiar with Nolan Chance, from the game Fortnite. 
Familiar and cool, grounded and approachable, Nolan continues to hold its steady place in the lower end of the US Top 100. 
Do you love Nolan but want some more inspiration? Other names inspired by Irish surnames include Nevan, Blaine, Riordan, Donnovan, and Callahan. For names that share a similar sound, Bowen, Milan, Noel, or Roland might appeal.

Nolan

Nora is a lovely, refined name that conjures up images of Belle Epoch ladies in fur-trimmed coats skating in Central Park. Long seen as a quintessentially Irish name though its roots are not in Ireland, Nora is a quietly stylish favorite that's tiptoed to the top of the popularity ladder.
 
Nora has two separate origin stories, as a derivative of both Honora and Eleanor. The Irish and Anglo-Norman version derives from Honora, based on the Latin word honor. The Hungarians spawned Nora as a short form of Eleonora, a variation of Eleanor.
 One of Nora's most prominent contemporary namesakes is the late witty writer Nora Ephron. Other notable Noras are the independent Ibsen heroine of A Doll's House, and the female half of the witty Nick and Nora Charles duo, adding up to a most desirable choice. 
 It can also be spelled Norah, as in Norah Jones.

Nora

Jaunty and raffish, Rafferty is one of the most engaging of the Irish surnames, used by Jude Law and Sadie Frost for their son. Fortunately, it doesn't still go by its original form: O'Raighbheartaigh.
 Raff and Rafe are two equally great nicknames.

Rafferty

No, the pronunciation--ro-SHEEN--isn't immediately obvious to the non-Gaelic viewer, but the sound of this shiny Irish version of Rose is pretty enough to make it worth considering. Very popular in its native Ireland, it's one of many <a href="Irish girl names https://nameberry.com/list/753/best-irish-girl-names">Irish girl names</a> finding a wider audience. Earlier generations Anglicized at as Rosaleen, but we stay stick to the original.
 The name has been associated with a 16th-17th century poem called Roisin Dubh (Dark Little Rose), the eponymous heroine of which is usually regarded as a personification of Ireland.
 Singer Sinead O'Connor has a daughter named Róisin.

Roisin

Ronan is the compelling legendary name of twelve Irish and Scottish saints that is now drawing some deserved attention; this cousin of the ascending Roman and Rowan was chosen by actor Daniel Day-Lewis and his writer-director wife Rebecca Miller in 1998, and more recently by actress Catherine Bell.
 Ronan is a Harry Potter name—that of a centaur who lives in the Forbidden Forest. Ronan Keating is an Irish singer, Ronan Farrow is a TV personality and Hollywood scion, and its presence as a surname is represented by young actress Saoirse Ronan.

Ronan

With its gentle sounds and earthy vibes, the name Rowan feels like a fusion of different styles. A word name, a surname, and a gender-neutral name, Rowan is rustic but trendy, blending the vibes of both Owen and Oakley. 
Just as it’s hard to fit Rowan into one category, it’s equally difficult to identify one definitive root. It could be considered an Anglicized form of the Irish name Ruadhán, meaning “little redhead” and it was used as an English surname before it became a given name. 
Alternatively, it could be linked to the rowan tree, whose name derives from Old Norse and means “to redden.” In folklore and mythology, rowan trees are seen as a symbol of protection and of life, adding extra meaning to Rowan. 
 To complicate matters further, some scholars identify Rowan as a girls’ name, deriving from Rowena and Rhonwen, meaning “famous friend” or “white spear.” This gives it solid credentials as a unisex name and lends it a slightly more rugged vibe. 
What is certain, however, is that Rowan has quickly become a stylish choice, chosen for over 3000 boys every year. Once an obscure name in the US, it rapidly climbed the charts during the 2010s and has now entered the Top 100 Boy Names for the first time. 
Rowan is popular in the UK, Canada, and the Netherlands too, but even more so among Nameberry users, where it ranks in the <a href=“https://nameberry.com/popular-names/nameberry/boys/allNameberry Top 1000”> Nameberry Top 30.</a> 
The most prominent bearer of the name is probably Rowan Atkinson, the British comic actor of Blackadder and Mr Bean fame. Other namesakes include the former Archbishop of Canterbury, Rowan Douglas Williams, and the Australian swimmer, Rowan Crothers. Pokémon fans and Sarah J. Maas readers might recognize it too as the name of a character in both the game franchise and in the Throne of Glass series. 
Gentle but powerful, stylish but not oversaturated, Rowan may well continue to climb the charts, so if you love Rowan but want to stray from the trends, Ruan, Sylvan, Lorcan, Lennox, Wren and Sloan might inspire you.

Rowan

Ryan’s use as a given name was inspired by the surname Ryan, a variation of the Irish O’Riain meaning "son of Rían." Rían is composed of the Irish-Gaelic elements rí, meaning "king" and an, a diminutive suffix. Ryan is considered a unisex name in the US, where variant spellings Ryann and Ryanne are also valid for girls.
 
Ryan has been one of the most popular <a href="https://nameberry.com/baby-names/168/irish-names">Irish names</a> in America for decades; it had been in the Top 20 since 1976, and dropped out in 2010 but still ranks highly, even though parents now have such a wide choice of Irish surnames, from Flynn to Finnigan, and newer Ry names like Ryder. Ryan (born Patrick) O'Neal first brought it to light in the mid-1960s, when parents saw it as a fresher and more spirited alternative to names like Brian and Kevin. In recent years, Ryan has taken off as a girl's name.
 Several male marquee Ryans still keep the name in the spotlight—think Ryan Seacrest, Ryan Reynolds, Ryan Gosling and Ryan Philippe.

Ryan

A common surname in Ireland that projects a complex image for a short-one-syllable name, combining spirit and substance. 

Shea

This hauntingly euphonious Choctaw name has re-entered the public domain, as memories of the outrageous actress Tallulah Bankhead have faded. For years, Tallulah was a name associated only with Bankhead, named for her paternal grandmother who was named after the Georgia town of Tallulah Falls.
 A modern hipster favorite, Tallulah had been chosen for their daughters by Philip Seymour Hoffman, Patrick Dempsey, Damian Dash, Rachel Roy and Sara Rue. The name was trail-blazed by Demi Moore and Bruce Willis for their now grown daughter. 
 When spelled Talulla or Talullah, it is also a traditional Irish name that was borne by two saints.

Tallulah is among the Feminine Feminist names is one of our hottest <a href="https://nameberry.com/blog/baby-name-trends-2024">baby name trends</a> of 2024.
