Irish Names for Boys

Also Anglicized as Dara and also spelled Daire in its native form, Darragh has an undeniably rugged appeal. It's used for both girls and boys in Ireland, but it's very popular in particular for boys.

Darragh

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

Malachy is one of the <a href="https://nameberry.com/irish-names">Irish baby names</a> that manages to strike the golden mean between familiarity and distinctiveness.
 
Malachy is also the anglicized version of Melaghlin, one of St. Patrick's first companions. It was borne by the High King Malachy, who defeated the Vikings at the Battle of Tara in 980. St. Malachy was a reformer who reorganized the church in Ireland after the Viking raids.
 
Another origin, via a somewhat circuitous route, is from the surname Mac Seachnaill, "son of Seachnall", the Irish form of Secundus.
 
Irish actor Cillian Murphy has a son named Malachy.

Shamus

Not your typical jovial Irish surname; but has a dark, craggy appeal, and Tag as a nickname.

Taggart

Caledon, the name of the arrogant Billy Zane character in "Titanic," is an Irish place-name related to Caledonia, the Latin word for Scotland thought to be derived from the ancient Celtic word for "hard."  Cal is a wonderful nickname, and Caledon an inventive way to get there.

Caledon

Perhaps too spicy for some, but this is a popular Gaelic surname that might appeal for those looking to honor a family branch. Curry Barker is the director of the horror film Obsession.

Curry

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

An earthy rock'n'roll name with multiple origins. The Roc was a giant bird in Middle Eastern legend.

Sheridan is one surname-name that hasn't come into style for either gender, though it was lightly used for boys around the turn of the 20th century and girls 100 years later. The name does have an attractive sound and an appealing meaning.

Sheridan

This Latinized form of a name that's well used in Italy and Spain is sometimes heard, oddly enough, in Ireland.

Curran

An upscale surname with a nice modern design connection to the creators of the Eames chair and other midcentury furniture classics, Charles and Ray Eames.


Eames

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

Keir is a single-syllable name that packs a punch, but also has a endearing quality about it thanks to its similarity to the word care. Sometimes used as a short form of the more popular Kieran, it could be derived from the Irish ciar meaning "black, dark".
 
Alternatively, it may be viewed as a variation of the Scottish Kerr, itself from the Old Norse kjarr, linking it to thicket, marshland, and brushwood. Other sources identify it with keir, an Old Scots word referring to a fort.
 
Notable bearers include Keir Dullea, an American actor who starred in 2001: A Space Odyssey and Sir Keir Starmer, a British politician who was the head of the Labour Party between 2020 and 2026 and the Prime Minister of the UK between 2024 and 2026. 
 
The name ranked in the UK charts back in the 90s and 2000s, but fell out of the stats in 2024, coinciding with Starmer's election. In the US, it has been quietly used since the 1960s and saw a small spike in popularity between 1968 and 1972, around the time of Dullea's star role in 2001: A Space Odyssey. A more recent year saw it given to 7 boys, with Kieran or Kyaire being the preferred options.

Keir

Conjures up pleasant images of lakes, but the pronunciation challenge makes the Anglicized Loughlin preferable.
