Irish names are often backed with meanings so interesting and magical, they make great icebreakers for first meeting new people.
Irish names are beautiful. It’s no wonder people around the globe are naming their children with beautiful Irish names that usually mean something pretty special.
Some of the most interesting and unique Irish names come from warriors and other characters in Irish mythology.
Some of the names on this list are quite well known, but special nonetheless, while others come from less well-known stories in Irish myth that you might not have heard of before. Let’s take a look at ten fierce Celtic warrior names for babies and what they mean.
10. Medb – warrior queen
Warrior queen Medb of Connacht, also known as Maeve or Meabh, was known for her ambition, strength, and formidable presence.
In Celtic tradition, Medb represents the embodiment of sovereignty—a sacred, otherworld figure whose marriage granted men the right to rule.
As a strong, formidable woman, she frequently clashed with the men of Ulster, including her former husband, King Conchobar mac Nessa. She is said to have been buried at the top of Knocknarea in County Sligo, positioned in view of her enemies in Ulster.
9. Fionn – one of Ireland’s most famous warriors
A popular name in Ireland and around the world, Fionn is a beautiful Irish name that comes from the legendary Irish warrior Fionn mac Cumhaill.
Anglicised as Finn McCool, in Irish mythology, Fionn mac Cumhaill is the leader of the Fianna bands of young roving hunter-warriors, but he was also known as being a seer and poet.
If you’ve seen an image of him before, he is most often depicted hunting with his hounds Bran and Sceólang, and fighting with his spear and sword.
One of the most well-known tales of this great Irish legend was that he built the famous Giant’s Causeway as stepping stones to Scotland.
8. MorrÃgan – one of the most powerful goddesses of the Tuatha Dé Danann
One of the more unique Celtic warrior names for your baby is MorrÃgan. The MorrÃgan was a leading figure in Irish mythology related to sovereignty, war, and fate.
The MorrÃgan was a shape shifter and often appeared as a crow or a raven. A formidable figure, she has the ability to foretell the outcome of battle, whether victory or death.
As one of the most important goddesses of the Tuatha Dé Danann, this is one powerful name to gift your child.
7. Brigid – a different kind of warrior
Not all warrior need to wield swords and spears. Not for Brigid, at least. In Irish mythology, Brigid was a healer and a poet.
Like the Morrigan, she belonged to the Tuatha Dé Danann. As the myth goes, when her son was killed in battle, she let out a cry so powerful that the warriors fighting on both sides laid down their weapons. If that isn’t fierce, we don’t know what is.
6. Chulainn Рfrom the great C̼ Chulainn
An increasingly popular Irish name for new babies, particularly in Ireland, is Chulainn, from the great warrior Cú Chulainn.
He’s an Irish warrior hero and demigod in the Ulster Cycle of Irish mythology who is renowned for his strength and fierce battles.
There is a lot of interweaving with the names on this list, because as the story goes, Cú Chulainn single-handedly defended all of Ulster from Queen Maeve’s army and her magic during the Cattle Raid of Cooley.
As the legend goes, even when he was dying in battle, he tied himself to a stone so it would appear he was still up and fighting, and so that he would die standing.
5. Manann – son of the sea
From the legendary ‘son of the sea’ Manannán mac Lir, Manann is certainly a powerful and unique name you could give to your little one.
Manannán mac Lir is a sea god who is part of the Tuatha Dé Danann, and is seen as a ruler and guardian of the otherworld.
He possesses many supernaturally imbued things and animals, including a self-navigating boat, a sword that can cut through any armour, and a horse that can ride across the surface of the ocean. Pretty cool, huh?
4. Conchobar – leader of a group of elite warriors
From the famous king of Ulster in the Ulster Cycle of Irish mythology Conchobar mac Nessa, Conchobar was a warrior king who was also the uncle of Cú Chulainn.
In Irish mythology, he leads a famous group of elite warriors called the Red Branch Knights, of which Cú Chulainn was also a member.
The story of how he became king is one of cunning and mischief. His mother, Ness, was the daughter of an old king. She convinced the reigning king, Fergus, to step down for just one year so Conchobar could rule.
Conchobar was so charming that the people begged him to stay, and the rightful king was forced to give up his throne.
3. OisÃn – son of Fionn mac Cumhaill
OisÃn was famously the son of Fionn mac Cumhaill. Don’t be fooled by the soft meaning of this Irish name, ‘little deer’, as just like Brigid, OisÃn was celebrated for things other than his strength.
While he was a strong man, he was celebrated as Ireland’s greatest poet. As the story goes, his mother was turned into a deer by an evil druid.
When she met Fionn mac Cumhaill, she turned back into a woman, but eventually she would return to her deer form. Thus, OisÃn was raised in the wild, something that contributed to his strength and resilience.
2. Fianna – band of warriors
Led by Fionn mac Cumhaill, the Fianna were a legendary, semi-mythological band of elite warrior-hunters in ancient Gaelic Ireland.
While not named after one specific person, the name Fianna is becoming more popular for baby girls in Ireland.
The name is beautiful, because the Fianna not only prioritised battle, but music, poetry, and the land, too. The name is like a metaphor for Ireland and its storied history. Backed by a strong, warrior meaning, this is certainly one fierce name to bestow upon your child.
1. Lugh – baby Lugh
If you were to name your child Lugh, you would have a lovely, unique Irish names that is linked to one of the most powerful deities in Irish mythology.
A skilled warrior and craftsman, Lugh was, like many names on this list, a member of the Tuatha Dé Danann.
His legacy is woven deeply into the fabric of Irish life, primarily through the famous harvest festival Lughnasadh. He was said to have established the festival to honour his foster mother Tailtiu.
The father of Cú Chulainn, he was said to possess expert skills in all trades, crafts, and arts, which was the reason why he was granted entry into the Tuatha Dé Danann after first being denied.
