Irish is one of the national languages of Ireland and, while the majority of the country uses English day-to-day, there are still many areas of life heavily influenced by Irish. One of these areas is names.
Irish-language names are some of the most well-loved in the country and continue to top the lists of popular baby names every year. Some Irish names have even become used worldwide.
Many Irish names have ancient origins — rooted in Celtic mythology — while some are beautiful Irish words that have been turned into names. Either way, Irish names are lovely, unique, and meaningful.
When it comes to Irish boy names, there are many to choose from. But, like everything, some are much more popular than others. Maybe due to it being the moniker of a famous actor, or perhaps because of its beautiful meaning - whatever the reason, certain names crop up again and again.
Some Irish names have even been adopted into English, and are used by people with no connection to Ireland.
Here is a list of some popular Irish boy names:Cillian (pronunciation: killy-un)
The name Cillian is probably most associated with Irish actor Cillian Murphy, but it is a very common name throughout Ireland - and has been for many years. The name has been adopted into English with the spelling Killian, but the Cillian spelling is much more common in Ireland.
There are some differing opinions about the meaning of the name, ranging from “war strife”, to “church” and ‘bright-headed’. Whatever the meaning, this is still a lovely and lyrical boy name.Darragh (pronunciation: dar-ah)
The history of the name Darragh goes back over a thousand years but remains popular to this day. Darragh comes from the Irish word doire, meaning “oak”.
This name has some alternative spellings (Dáire and Dara), but these forms are less common. Nowadays, the latter spelling is sometimes used as a girl’s name, but it is much more popular for boys.Eoin/Eoghan (pronunciation: owe-in)
This name is very common for boys and men of all ages in Ireland, with either spelling seen regularly. Interestingly, while these names are pronounced the same, they are derived from different roots.
Eoin means “God is gracious” and is derived from Latin roots, while Eoghan is Celtic and means “of the yew tree”. Eoin is closely related to the name Seán, as both are considered to be the Irish form of John.Liam (pronunciation: lee-um)
Liam is a male name of Irish origin that is popular not only in Ireland but also around the English-speaking world. It means “guardian”.
The name Liam is a shortened form of either Ulliam (an old Irish name) or William (a Germanic name).
There are many famous people with this name, including the English singer Liam Payne (from the band One Direction) and the Australian actor Liam Hemsworth.Seamus (pronunciation: shay-muss)
Seamus is a very popular male name in Ireland, particularly among older generations.
This name is often considered to be the Irish form of the English name James. Its meaning is “supplanter” or “one who plants”.
Less commonly, the name can be spelled Seamas. The most well-known person with this name was the Irish poet Seamus Heaney, a laureate of the Nobel prize in Literature.Seán (pronunciation: shawn)
Seán is a popular Irish name that has become well-used throughout the English-speaking world. Like the name Eoin, it means “God is gracious”.
Because it has been adopted as a common name for English speakers, often it is incorrectly spelled without the fada (accent). This is rather amusing for Irish speakers as the word sean (with no fada) means “old”.
The name is also often anglicized to Shaun. There are many famous people with this name, including Sean Bean, Sean Connery, and Sean Paul.
Mythology and folklore are important in the history and culture of Ireland and are often a source for traditional Irish names.
Many boys with Irish names are - perhaps unknowingly - using the moniker of a fierce warrior or strong king from mythology. These names have been around for thousands of years and are still popular today. Here are some well-loved traditional Irish boy names:Cian (pronunciation: key-un)
This lovely boy's name means “ancient” or “enduring one”. Cian was an important figure in Irish mythology; he is the son of the god of medicine, and the father of Lugh - the god of the sun and a famous warrior.
This name can be spelled with or without a fada on the letter i (i.e. Cian or Cían), with no change in pronunciation - though it is most commonly spelled without.Conor (pronunciation: conn-urr)
The name Conor (which is sometimes spelled Conner) comes from the legend of Conchobar mac Nessa, a much-loved king in Irish mythology. The name means “lover of wolves” and, over time, it was shortened and simplified to Conor. It is also related to the very common Irish surname O’Conner.Diarmuid (pronunciation: deer-mid)
The meaning of the name is not completely clear, but the most likely meaning is “free from envy”. This name can also be spelled Diarmaid and is often anglicized to Dermot.
This name is mostly connected with the love story of Diarmuid and Gráinne, who ran away and roamed the countryside for years, so they could be together.Fionn (pronunciation: fyun)
Fionn is another name from Irish mythology, and it means “white” or “fair”. Irish mythology, Fionn mac Cumhaill was the fearless leader of a band of warriors called the Fianna.
The name has gone up and down in popularity over the years, but it is very popular today, with it being ranked number 14 of the top baby names in Ireland in 2021 (according to cso.ie).Naoise (pronunciation: nee-sha)
The name Naoise is less common than the other traditional boy names on this list, but just as rooted in Celtic mythology.
In Irish mythology, Naoise was a hunter, singer, and warrior, who was married to Deirdre, the most beautiful woman in Ireland. After his death, it is said that Deirdre died of a broken heart.
While this is primarily a boy's name, in more recent years, it has been used for girls as well.Oisín (pronunciation: ush-een)
The name Oisín has been popular in Ireland for centuries, and remains so today, with it being among the top twelve baby names in 2021 (cso.ie).
In Irish mythology, Oisín was the son of Fionn mac Cumhaill, and a fierce warrior in his own right. Along with the connections to tradition, the name also has a very sweet meaning - “fawn” or “little deer”.
Not all Irish names are taken from ancient myths and folklore; many have become popular much more recently. Some might have older origins, but it is the recent growth in popularity that makes them truly modern names. These modern Irish boy names are just as lovely as the more traditional ones:Daithí (pronunciation: dawh-hee)
This name means “swiftness” or “nimbleness”. It is often incorrectly thought to be the Irish form of the name David, but it is completely unrelated.
Some choose to spell this name slightly differently - Dáithí, Daithi, or Dathí - but the pronunciation is usually the same.Finn (pronounced as spelled)
Finn is a relatively common name in the English-speaking world, but many people don’t know its Irish origins. It is another form of the name Fionn and, like Fionn, it means “fair”.
Finn is much more common as a baby name today. It’s been among the top 10 baby names in Ireland for the last 2 years (cso.ie).Páidí (pronunciation: paw-dee)
Páidí is a lovely boy name meaning “nobleman”. The name is a diminutive of Pádraig, the Irish form of Patrick.
Páidí - and the anglicized version Paudie - have been used as nicknames for decades, but in more recent years, both have been used more and more as given names.Rían (pronunciation: ree-un)
This modern boy's name is derived from the Irish word Rí, meaning “king”. It’s safe to say that this is a modern name, having shot up in popularity over the last few years. The name was practically non-existent on Ireland’s baby name list as recently as 2017, and is now the fifth most popular baby name in the country (cso.ie).Senan (pronunciation: senn-in)
Senan is a beautiful boy name that has really grown in use over the last decade. It means “old” or “wise”. It can also be spelled with a fada and, therefore, with an emphasized pronunciation of the second syllable: Senán (pronounced sen-awhn). The name is most associated with a famous 6th-century monk, Saint Senan.Tadhg (pronunciation: tie-g)
While this name has been around for centuries - and it’s not uncommon to meet men of all ages with this name - it has recently had a large rise in popularity. This shows that it’s a truly modern boy name, which never goes out of fashion. Perhaps this is down to the lovely meaning behind the name - “poet” or “philosopher”.
While Irish names may be rare in a lot of the world, most of the names listed so far are relatively common in Ireland. There are, however, many names that are used a lot more rarely. These unique Irish boy names are just as nice as their more popular counterparts, and have equally lovely meanings:Cuán (pronunciation: coo-awn)
Cuán is a lovely boy name meaning “little hound”: this name is formed as a combination of the Irish word cú, meaning hound, and the diminutive an.
Some people choose to spell this name without the fada, changing the pronunciation slightly to coo-in. Either way, it’s still a gorgeous name for boys.Faolán (pronunciation: fway-lawn)
This lovely boy's name means “little wolf”. It can also be spelled without the fada, which changes the pronunciation slightly to fway-linn. While this is a unique first name, it has given rise to the relatively common Irish surname Phelan.Fiach (pronunciation: fee-uk)
Fiach is a unique boy name meaning “raven”. This name was practically nonexistent for newborn babies until the 1980s (cso.ie), and even now there are very few people with the moniker. Another, equally unique, form of this name is Fiachra.Iarlaith (pronunciation: ear-lah)
This name comes from the Irish thiar (west) and flaith (leader), resulting in the meaning “leader of the west”. There is an English version of this name - Jarlath - which is equally as unique.Muiris (pronunciation: mur-ish)
Coming from the Irish word muir meaning “sea”, this name is thought to mean “sea warrior” or “mariner”. It’s often used as the Irish form of the name Maurice, but the names are unrelated. In history, several Irish medieval kings bore this name - though with the more complicated spelling of Muirgheas.Odhran (pronunciation: or-in)
This unique boy's name means “dark green”. It can be spelled Oran or with a fada - Odhrán. For the latter, the pronunciation changes, as the a becomes elongated (more like oh-rawn).
While this is the name of many Irish saints, it is not that common to meet a person named Odhran in Ireland, which makes it a lovely and unique name.Conclusion
While this is only a selection of Irish boy names, it should give a good insight into the wonderful variety of names that exist in the Irish language.
Whether they are very popular, or much more unique, all Irish names have a lyrical quality to them, coupled with fascinating meanings.
