You’re probably thinking of Patrick. Or maybe Sean. Honestly, if you walk into a pub in Dublin or a GAA pitch in Kerry, you'll hear those names, sure. But the reality of male names in Ireland right now is a weird, beautiful collision of ancient Viking history, stubborn Catholic tradition, and a sudden, massive surge in "Old Irish" names that even most grandfathers can't spell.
Naming a boy in Ireland used to be predictable. You had a John, a Mary, a Patrick, and a James. It was almost a legal requirement to name the first son after the paternal grandfather. We were stuck in a loop. But things changed. Ireland got secular, globalized, and then, ironically, obsessed with its pre-colonial roots.
Now, the Central Statistics Office (CSO) releases its annual data, and it’s a battleground. You've got the "Internationalist" names like Jack and Noah fighting for space against "Deep Heritage" names like Tadhg or Oisín. It’s not just about what sounds nice anymore. It’s about identity.
Why Jack Still Rules the Roost
For the better part of two decades, Jack has been the king. It’s a phenomenon. Since 2007—with only a tiny blip where James took the lead—Jack has been the most popular of all male names in Ireland.
Why? It’s short. It’s punchy. It works in New York, London, and Cork.
But look closer at the data. While Jack sits at the top, it’s actually losing "market share." In the late 90s, the top names accounted for a huge percentage of all babies born. Today, parents are desperate for "different." We’re seeing a fragmentation. A name that would have been 50th on the list twenty years ago is now cracking the top ten because everyone is trying so hard not to be "another Jack."
The Rise of the "Fada"
If you aren’t from around here, the fada (that little slanted line over a vowel, like á or ó) is everything. It changes the pronunciation entirely. Without it, the name is technically spelled wrong.
Take Sean vs. Seán. Or Oisin vs. Oisín.
The surge in Irish-language names isn't just a trend; it's a reclamation. For a long time, names like Tadhg (pronounced like "tiger" without the 'er') were seen as "too rural" or "too old-fashioned." Now? It’s one of the most stylish names you can give a kid in South Dublin. It’s a power move. It says, "We know our history."

The Most Popular Male Names in Ireland Right Now
If we look at the most recent official statistics from the CSO, the top tier is surprisingly stable, yet the "vibe" is shifting.
Jack remains the heavyweight champion. It's safe.
Noah is the international interloper. It’s massive across Europe and the US, and Ireland isn't immune.
James is the eternal classic. It never goes out of style because it’s impossible to hate.
Rian has surged recently. It sounds like Ryan, but it’s actually the Irish word for "King" (Rí) with a diminutive suffix. Basically, "Little King."
Oisín and Fionn are the mythological heavy hitters.
You’ve gotta realize that these names aren't just sounds. Oisín was the son of Fionn Mac Cumhaill in the Fenian Cycle of Irish mythology. He spent 300 years in Tír na nÓg (the Land of Youth). When parents pick these names, they are literally reaching back into the Iron Age. It’s a bit more "metal" than naming your kid after a TikTok star.
Spelling is the New Battleground
Here is where it gets tricky. There is a massive divide between the "Anglicized" Irish names and the "Traditional" ones.
Take the name Cian. It’s popular. It’s easy.
Now take Caoimhín. That’s the original Irish for Kevin.
Hardly anyone names their kid Kevin anymore. It’s peaked. It’s a "dad name." But Caoimhín? That’s fresh.
We see this with:
- Cillian (think Cillian Murphy) vs. Killian. The 'C' version is now vastly more popular in Ireland because the letter 'K' doesn't exist in the Irish alphabet. Using a 'K' feels "Americanized" to a lot of Irish parents.
- Donnacha. It’s a mouthful for non-locals (DUN-aka). It means "brown-haired warrior."
- Senan. Often confused with the French "Stéphane" or something similar by tourists, but it's a pure Gaelic name.
The "Grandparent" Cycle
There is a very specific thing happening with male names in Ireland involving what I call the "70-year rule."
Names that were popular in the 1940s and 50s are currently considered "uncool." You won't find many babies named Gary, Derek, or Keith. These are "middle-aged man" names.

However, names from the 1910s and 20s are making a massive comeback. Arthur is climbing. George is appearing again. Even Paddy—once a name people avoided because of certain stereotypes abroad—is being reclaimed as Pádraig or simply Patty in a modern, ironic, or deeply traditional sense.
The Catholic Church’s influence has waned, but its naming legacy is stubborn. For decades, you had to have a saint's name to be baptized. That’s why there are so many men named John-Paul or Michael. Today, that restriction is gone, but the ghost of it remains. People still lean toward "strong" names.
Surprising Trends: The "Surnames as First Names" Craze
Influenced heavily by American media, Ireland has started doing something it never used to do: using Irish surnames as first names.
Traditionally, Murphy, Kennedy, or Quinn were only last names. If you called a kid "Quinn" in 1980, people would ask, "Quinn what?" Now, Quinn and Finn (though Finn is also a first name) are everywhere. Cullen is another one. It feels modern, even though the roots are centuries old.
Pronunciation Guide for the Perplexed
If you’re looking at male names in Ireland and feeling a bit lost, you aren't alone. Irish is a Goidelic language. The phonics are not English.
- Tadhg: Like "Tyge" (rhymes with tiger).
- Eoin: Pronounced "Owen." It’s the Irish version of John.
- Cathal: Pronounced "Cahal." The 't' is silent. It means "Battle Ruler."
- Darragh: Pronounced "Dara."
- Odhrán: Pronounced "Oran." It means "little pale green one." Weird, but it sounds beautiful.
Honestly, the complexity is the point. In a world where every kid is named after a tech billionaire or a fruit, Irish parents are finding uniqueness in their own "difficult" spelling. It’s a silent protest against the homogenization of the English-speaking world.
The Regional Divide
Naming isn't uniform across the island. If you go to the Gaeltacht (Irish-speaking regions) in Donegal or Galway, you’ll find names that haven't shifted in a thousand years.
In Dublin, you see more "posh" English-sounding names or very modern, short Irish names like Finn. In the rural west, you might find more traditional iterations. However, the internet has flattened this out quite a bit. A trend in Dublin hits Dingle in about five minutes now.

What’s Falling Out of Favor?
It’s worth noting what people aren't picking.
The "Standard Saints" are in trouble.
- Peter is way down the list.
- Paul has plummeted.
- Mark is rare for newborns.
These names are seen as "Gen X" or "Boomer" names. If you name your baby Paul in 2026, people might assume he’s named after his grandfather, not because the parents just loved the name.
Actionable Advice for Choosing or Researching Irish Names
If you are actually looking to name a human being and want something that feels authentically Irish but won't cause a lifetime of spelling trauma, here is the move.
First, decide on the "Spelling Tolerance."
If you live outside Ireland, a name like Tadhg or Caoimhín is going to be a struggle. Every. Single. Day. If you're okay with that, go for it—they are stunning. If not, look for "Translation Friendly" names like Liam, Finn, or Oscar. (Fun fact: Oscar is a deeply Irish name, coming from 'Os' meaning deer and 'cara' meaning friend).
Second, check the CSO Baby Names website. They have a tool where you can see the popularity of a name over time. If a name is skyrocketing (like Rian), it might be the "new Jack" in five years. If you want something unique, look for names in the 50-100 rank range.
Third, verify the meaning. Some Irish names have "darker" meanings which some people love. Lorcan means "Little Fierce One." Cashel means "Castle" or "Stone Fort."
Finally, don't forget the fada. If you're going to use an Irish name, use the diacritics. It’s the difference between a name that’s "kinda" Irish and a name that actually carries the weight of the language.
The landscape of male names in Ireland is more diverse now than it has been in the history of the state. We’ve moved past the era of ten Patricks in a single classroom. Whether it’s a revival of a mythical warrior name or a modern take on a surname, Irish naming conventions are currently in a "Golden Age" of creativity.
Next Steps for Your Research
- Visit the Central Statistics Office (CSO) website to use their "Baby Name Gallery" tool—it lets you download the exact rankings for every year since 1964.
- Check the Irish Names and Surnames database by Rev. Patrick Woulfe if you want the deep, scholarly etymology of Gaelic names.
- If you’re choosing a name, say it out loud with your surname. Irish names often have a rhythmic "lilt." A name like Finnian O’Sullivan flows differently than Jack O’Sullivan.
