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:

Callum, a charming Scottish name high on the list in England, Scotland and Northern Ireland, is rising through the ranks in the US now too. And it comes complete with the easy nickname Cal.
- 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.
- Kieran
Origin:
IrishMeaning:
"little dark 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.
- Quinn
Origin:
IrishMeaning:
"descendent of Conn"Description:
Quinn is the Anglicized version of the Irish patronymic surname Ó Cuinn, meaning "descendent of Conn." Conn has two possible derivations—the Old Irish cond, meaning "intellect," or cenn, meaning "chief." One of the most notable Quinn clans was from County Tyrone in Northern Ireland.
- 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.
- 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.
- 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.
- Torin
Origin:
IrishMeaning:
"chief"Description:
Though it has a Scandinavian ring, this is an out-of-the-ordinary Irish family name. The hard 'T' at the beginning prevents it from sounding as feminine as, say, Loren. Torin's Passage was an early video game.
- 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.
- 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.
- 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.
- 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.
- Fiadh
Origin:
IrishMeaning:
"wild"Description:
Fiadh is the fastest-rising girls' name in Ireland, derived from the ancient root word for "wild". The Anglicized form Fia is one we might see rising in the US as well – to take the place of its popular cousin Mia.
- 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:

"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.
- Fia
Origin:
Irish or Portuguese or ItalianMeaning:
"wild or 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.
- Fallon
Origin:
IrishMeaning:
"leader"Description:
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.
- Cian
Origin:
IrishMeaning:
"ancient"Description:
A handsome Irish name for boys, very popular in that country, but in the US this traditional spelling might cause pronunciation problems. Still, whether Cian or Kian, it's simple and straightforward enough for the initiated. Cian is rising in the British popularity charts. This was the name of several legendary figures, including Cian, son of the god of medicine. His own son was Lugh, the sun god and father of the Ulster warrior Cuchulain and Cian is also the name of the son-in-law of the high king Brian Boru. So very well connected.
- Rory
Origin:
IrishMeaning:
"red king"Description:
Rory is a buoyant, spirited name for a redhead with Celtic roots. The name Rory is getting more popular overall, but for the past few years has been trending decidedly toward the boys' side -- however, it's been rising to new heights for girls in recent years.
