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.

- Quinn

IrishMeaning:
"descendant of Conn, chief leader, intelligence"Description:
Quinn is one of the first popular Irish unisex surnames, a strong and attractive choice on the rise for girls but still popular for boys. Quinn was used for about 2600 baby girls and 600 boys in the US last year.
- 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.
- 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.
- Sullivan
Origin:
Irish surnameMeaning:
"black-eyed one"Description:
Sullivan is a jaunty Celtic three-syllable name, with a real twinkle in its eye. It was immortalized in the 1930s classic film Sullivan's Travels and was chosen for one of Patrick Dempsey's twin boys. Nickname Sully is equally jaunty.
- 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.
- 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.
- 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.
- Murphy
Origin:
IrishMeaning:
"sea warrior"Description:
This jaunty Celtic surname -- the most common family name in both Ireland and the US -- is totally viable as a first. The arguably most famous Murphy is TV's Murphy Brown, and indeed the name is twice as common for baby girls as for baby boys today. But still, it's solidly gender neutral and works equally well for all sexes.
- Kian
Origin:
Irish; PersianMeaning:
"ancient; king"Description:
A friendly Irish and Persian name chosen by Geena Davis for one of her twin boys, whose father is Iranian.
- 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.
- 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.
- Eamon
Origin:
Irish variation of EdmundMeaning:
"wealthy protector"Description:
Eamon is one of the traditional Irish names 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.
- 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.
- 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.
- 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.
- Aoife
Origin:
Irish GaelicMeaning:
"beautiful, radiant"Description:
Aoife, pronounced EE-fa, is derived from the Irish word aoibh, meaning "beauty." Aoife was borne by several different heroines of ancient Irish legend. In one tale, she was the fiercest woman warrior in the world and enemy of her twin sister, Scathach.
- Finnegan
Origin:
IrishMeaning:
"fair"Description:
If you like the Finn names and love James Joyce, Finnegan is extremely winning. Will & Grace 's Eric McCormack chose the Finnigan spelling for his son. And of course Finnegan gains you access to the great short form Finn.
- 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.
