Written by Jane Chadwick on Jun 13, 2022 | 0 Comments

Over the years, we've been honored to provide special gifts for expectant parents, and new arrivals. Many choose to engrave these cherished heirlooms with their child's name and date of birth. Which got us thinking about baby names.

Where to find authentic Irish baby names?

With an Irish boy's name, Liam, topping the baby name charts in the US since 2017, it seems names with gaelic and celtic origins are on the radar for many prospective parents.

Those on the hunt for an authentic and unique moniker for their little one might search the archives of the library of Ireland or check the Irish central statistics office for the most popular names in Ireland by year.

Or they could read our collection of 21 Irish names for girls and for boys. We've pulled together the most popular Irish names in Ireland as identified by the Central Statistics Office. We’ve also included the origin and meaning of these lovely names as well as a helpful pronunciation guide. Some Irish names can be challenging for those not acquainted with gaelic!

21 Unique Irish names for Boys

1. Conor

How it's said in Ireland: Con-er or Con-or depending on where you are

Roughly translated, Conor means "Lover of Wolves" or "Lover of Hounds". Found in Irish legends and the name of an Irish high king Conaire Mór, the name Conor was always popular in Ireland. In the top 100 names for decades, Conor rose to 1st in 90's and has remained in the top 10 ever since. It was the 4th most popular boy's name in Ireland in 2021. Can also be spelled Connor (279th).

2. Rían

How it's said in Ireland: Ree-an

The 5th most popular boy's name in Ireland in 2021, Rían is the gaelic spelling for another popular Irish name, Ryan (35th in 2021), or without the fada, Rian (104th in 2021). This is an Irish name so ancient its meaning was lost before records began. But many today ascribe it to the Old Irish word rí, meaning king - so with this interpretation, this name roughly translates as “little king”.

3. Liam

How it's said in Ireland: Lee-um or Lee-am depending on where you are

The Irish short form of Uilliam, the gaelic for strong-willed warrior and protector. A popular name worldwide, with Liam in top 100 in US, Germany, Canada, France, Spain, Sweden, Belgium and Switzerland.

4. Cillian

How it's said in Ireland: Kil-ee-an

From the gaelic cill meaning church with the suffix -ín, used affectionately to indicate a diminutive status. Cillian, roughly translated, means little church.

6. Oisín

How it's said in Ireland: Uh-sheen

An Irish name with lovely meaning and mythological ties, it's no wonder Oisín has been a consistently popular name choice and 12th for boys in Ireland in 2021.

Both the gaelic and the anglicized version of this Irish name are hugely popular in Ireland ranking 13th (Finn) and 14th (Fionn) in 2021.

10. Patrick

How it's said in Ireland: Pat-rick

One of the most quintessentially Irish names going despite not actually being a name of gaelic origin, Patrick has been a hugely popular name in Ireland for centuries.

11. Cian

How it's said in Ireland: Key-an or key-in depending on where you are

Father to the warrior King Lugh, Cían is another gaelic name with mythological roots. Cían is gaelic for "enduring one," but it is more common to see the name without the fada (accent) today, ranking 23rd in 2021 as "Cian".

My Irish Jeweler

Born in Dublin but reared in Canada, as a child I had an interest in Ireland that will be familiar to many young emigrants. I was completely fascinated, wanting to know all about the land of my parents and grandparents. Rare month-long family trips back "Home" cemented my love for Ireland. And I wore my Irish heritage with pride, sporting my tiny silver Claddagh gifted to me by my Irish grandparents until my finger grew too large for it!

As a young adult I moved back to Dublin, studying Geology and Mineralogy in university at historic Trinity College Dublin. After living in Denmark and the Netherlands working as a scientist and university mineralogy lecturer, I finally settled back home in Dublin. I joined the growing family at My Irish Jeweler in 2016, bringing my useful knowledge of metals and minerals as well as my perspective as an Irish emigrant with a love for HOME.
