Unique Irish names come in two main varieties. One is Irish names from Ireland's native Irish language, such as Saoirse and Siobhan. These Irish language or Gaelic names tend to be most popular in Ireland itself, though many have emigrated in recent years.
The other brand of unique Irish baby names popular especially in the US are last names used as first names. Irish last names such as Riley and Quinn are technically gender neutral as first names, but they tend to be used more often in the US for girls.
While classic Irish names such as Bridget and Patrick are of course still used in Ireland, the US, and other countries, many parents are more interested today in finding unique, uncommon, rare, and unusual Irish names.
The Irish names here may be more or less unusual and unique depending on where you live. Fiadh and Aoife not going to turn any heads in Dublin, but they'd definitely qualify as unique Irish girl names in the US. And unique Irish boy names from the American point of view, such as Cian or Seanan, are similarly commonplace in Ireland itself.
Here is a large collection of rare, uncommon, unusual, and unique Irish names, ordered by their current popularity on Nameberry.

- Callum
Origin:
Scottish form of Columba, LatinMeaning:
"dove"Description:
Callum is a gentle, charming name of Scottish origin, that is a popular choice across the UK. In the US, it was a rare option until the late 2000s, however, since 2017 it's been rising up the ranks. Complete with easy, breezy and cool nickname Cal, it climbed more than 60 places in the US in 2024, placing it just outside the Top 150.
- Rafferty
Origin:
IrishMeaning:
"floodtide, abundance, prosperity"Description:
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.
- Kieran
Origin:
IrishMeaning:
"little black-haired one"Description:
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.
- Cillian
Origin:
IrishMeaning:
"war strife or church"Description:
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.
- Orla
Origin:
IrishMeaning:
"golden princess"Description:
Orla is an Irish name closely associated with the high king Brian Boru, as it was the name of his sister, daughter and niece. It was very popular in the Middle Ages – the fourth most popular name in twelfth century Ireland – and has become popular again in Ireland, Scotland, England and Wales today. In Irish, the name is commonly spelled Orlaith or Orlagh.
- Callahan
Origin:
IrishMeaning:
"bright-headed"Description:
Callahan, the simpler spelling of Callaghan, is a rhythmic jig of a name whose history harks back to the ancient King of Munster. In the Dirty Harry movies, the Clint Eastwood character is Harry Callahan.
- Saoirse
Origin:
IrishMeaning:
"liberty"Description:
Before the young Irish actress Saoirse Ronan made her mark in the films Ladybird and The Lovely Bones, few of us had heard this name, let alone known how to pronounce it. But now it is slowly way edging its way into the mainstream, particularly, of course, with parents who have Irish roots. It made its first appearance in the US Top 1000 in 2016, when it was the third-fastest-rising girls' name.
- Lorcan
Origin:
IrishMeaning:
"little, fierce"Description:
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.
- Teagan
Origin:
Irish or WelshMeaning:
"little poet or fair"Description:
As Meghan/Megan and Reagan/Regan show signs of wilting, along comes Teagan to take up the slack: definitely one to consider. The vast majority of American babies named Teagan are now girls. A variant spelling is Teaghan.
- Torin
Origin:
Irish, Spanish, FrenchMeaning:
"little chief, little hill, mound; holding fast; bull"Description:
Though it has a Scandinavian ring (a la Thorfinn), Torin is in fact a multicultural choice, an occasional feature in the UK Top 1000, and given to around 150 boys in the US each year. Connected to nature, power, and astrology, it is a distinctive yet trendy sounding choice.
- Fiadh
Origin:
IrishMeaning:
"wild"Description:
Fiadh is the fastest-rising girls name in Ireland, derived from the ancient root word for "wild". Sassy but gentle at the same time, it also entered the England and Wales Top 1000 in 2020 and has been steadily rising ever since.
- Tadhg
Origin:
IrishMeaning:
"poet"Description:
The name of several ancient kings and princes of Ireland, Tadhg became so common at one point that it was used to represent a kind of Irish Gaelic everyman, or man in the street, as Paddy and Mick would later. Tadhg has seen a major resurgence in recent years and is also now ranked in England.
It is sometimes used as the Irish equivalent of Timothy and is also anglicized as Teague and Thaddeus. Tadleigh and Thad are pet forms. Pronunciation is like tide ending with a g or like the first syllable of tiger.
- Darcy
Origin:
Irish, FrenchMeaning:
"dark one; from Arcy; from the fortress"Description:
A favorite in England and Wales, Darcy is a unisex option with delicacy, grace, and strength. Associated with classic literary and courtesy thanks to Jane Austen's hero, Mr. Darcy, and Bridget Jones's Mark Darcy, its image was partly transformed by English ballerina Darcey Bussell, who helped popularize it for girls.
- Niamh
Origin:
Irish GaelicMeaning:
"bright"Description:
Niamh, derived from the Old Irish Niam, is an ancient Irish name that was originally a term for a goddess. In Irish myth, one who bore it was Niamh of the Golden Hair, daughter of the sea god, who falls in love with Finn's son Oisin and takes him to the Land of Promise, where they stayed for three hundred years. Niamh can be Anglicized as Neve, Nieve, or Neave.
- Fia
Origin:
Irish, Portuguese, ItalianMeaning:
"wild, weaver"Description:
Fia may be most notable at this moment as the Anglicized version of the Irish Fiadh, one of the fastest-rising names in the Republic of Ireland. The meaning of Fia or Fiadh is sometimes given as "deer" but that's in the sense of a wild deer, as the name relates to the ancient word for wild.
- Cormac
Origin:
IrishMeaning:
"charioteer"Description:
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.
- Kian

A friendly Irish and Persian name chosen by Geena Davis for one of her twin boys, whose father is Iranian.

Manx, IrishMeaning:
"little blackbird"Description:
Typically spelled as Lonán in Ireland, Lonan is its Manx form, though it could also be considered the anglicized form too. The name comes from the Irish lon meaning "blackbird", paired with a diminutive suffix, making this a charming nature-related choice that could make a nice Logan/Conan alternative.
- Oona
Origin:
Irish, variation of UnaMeaning:
"lamb"Description:
Oona is a name made famous by Eugene O'Neill's daughter, who became Charlie Chaplin's wife. One of the original Oona's granddaughters was named after her, and is now an actress famous in her own right for playing Talisa of Volantis in HBO's "Game of Thrones." The double-o beginning gives their name a lot of oomph.

"rowan tree; redhead; sandalwood; ascension"Description:
Simultaneously a name of Hindi and Sanskrit origin, a spelling variation of the popular Rowan and an anglicized form of Irish Ruadhán, Rohan is a cross-cultural choice.
