130+ Unique Irish Names
Updated Thu Sep 14 2023
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 according to their current popularity on Nameberry.
RELATED:
- 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.
- 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.
- Callum
Origin:
Scottish form of Columba, LatinMeaning:
"dove"Description:
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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Caoimhe
Origin:
Irish, ScottishMeaning:
"beautiful"Description:
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.
- 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.
- Oisin
Origin:
IrishMeaning:
"little deer"Description:
Oisin is one of the most popular Irish baby names in its native land, though largely unknown in the US. The original Oisin was the mythological son of Finn McCool and Sadb, the goddess who was changed into a deer. A legendary war hero and poet, Oisin had a name that is also reminiscent in sound of the ocean. Pronounced correctly, this name has an attractive sheen.
- Siobhan
Origin:
Irish GaelicMeaning:
"god is gracious"Description:
Siobhan is the Irish variation of Joan, which is derived from the ancient Anglo-Norman name Jehanne. In this way Siobhan is indirectly related to the name Sinead—the Irish form of Jeannette, which also derived from Jehanne—although Sinead is not a nickname for Siobhan. Siobhan was the name of several early Irish queens and was introduced to the American public by the actress Siobhan McKenna.
- Kian
Origin:
Irish, variation of CianDescription:
A friendly Irish name chosen for one of her twin boys by Geena Davis.
- 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.
