Irish Baby Names
Explore 275 irish names, each with its own meaning, history, and pronunciation. Find one that carries the stories you want your child to grow up with.
Irish names carry centuries of Gaelic heritage, saintly tradition, and mythic storytelling. They are among the most musical names in European naming, and many travel easily beyond Ireland once the pronunciation has been heard once.
A short history
The Irish naming tradition is built in three layers. The oldest comes from the sagas: Oisin, Fionn, Cormac, Maeve. A second wave arrived with early Christianity, bringing the saints: Ciaran, Brigid, Patrick, Brendan. The third, and most recent, is the modern Gaelic revival of the 19th and 20th centuries, which brought names like Saoirse and Niamh back into everyday use.
Naming traditions
Traditional Irish families often named children for grandparents in a fixed order (eldest son for his paternal grandfather, eldest daughter for her maternal grandmother), which is why the same names recur across generations in Irish records. The suffix -an (as in Ronan, Oisin) is a diminutive meaning 'little', so Ronan is 'little seal' and Oisin is 'little deer'.
Sound and style
Irish spelling can look unfamiliar but follows consistent rules. The 'mh' and 'bh' consonant clusters soften to a v or w sound. The 'ao' vowel pair reads as a long ee. Most popular Irish names anglicise cleanly; a small group (Tadhg, Caoimhe, Oisin) need a brief pronunciation note but reward the effort.
Frequently asked
What is a traditional Irish naming pattern?
Traditional Irish families often named the eldest son after his paternal grandfather, the eldest daughter after her maternal grandmother, and so on. This is why the same names cluster through generations in Irish family records.
Why do Irish names have unusual spellings?
Irish is a different language with its own spelling system, and most Irish names retain the Gaelic spelling rather than being transliterated. Once you know the basic rules ('mh' and 'bh' sound like v or w, 'ao' sounds like ee), most names become readable.
Brendan
“Prince, brave”
Brendan comes from the Old Irish word meaning prince or brave one, carrying connotations of nobility and courage. The name is most famously associated with Saint Brendan the Navigator, the sixth-century monk whose legendary Atlantic voyage captured the medieval imagination. It is a name that speaks to both leadership and adventurous spirit.
Brian
“Noble, high”
Brian is believed to derive from an old Celtic root brig or bri meaning high, noble, or strength, related to the Gaulish and Brittonic briga meaning hill or high place. The name entered legend through Brian Boru, the tenth and eleventh-century king who unified Ireland and defeated the Viking forces at the Battle of Clontarf in 1014. His legacy cemented Brian as one of the most enduringly prestigious names in Irish history, and it has remained in consistent use across the Irish diaspora ever since.
Brid
“Exalted one”
Brid is the original Irish form of Bridget, derived from the pre-Christian Irish goddess Brigid, whose name is believed to mean exalted one, high one, or the powerful one. The goddess Brigid was associated with poetry, healing, and smithcraft, three of the most respected arts in early Irish society. Saint Brigid of Kildare, Ireland's most beloved female saint, bears the same name and shares her feast day with the ancient festival of Imbolc on 1 February.
Bridget
“Exalted one, strength”
Bridget is the anglicised form of the Irish Brighid, meaning 'exalted one' or 'the high one'. The name uniquely bridges pagan and Christian Irish traditions, belonging to both the pre-Christian goddess of poetry, healing and smithcraft, and Saint Brigid of Kildare, one of Ireland's three patron saints.
Brody
“From the muddy place”
Brody originates from the Irish surname O Bruadair or from the Gaelic word brodach, possibly referring to a muddy or ditched place. As a place-name turned given name, it carries the rugged, earthy character of the Irish landscape. In recent decades it has become a popular first name used freely for both boys and girls.
Bronagh
“Sorrowful”
Bronagh derives from the Irish word "bronach," meaning sad or sorrowful. While the literal meaning might seem melancholic, the name carries a profound beauty in Irish tradition, where sorrow was often associated with depth of feeling, poetic sensibility, and spiritual wisdom. Saint Bronagh, a revered sixth-century Irish saint, lent the name an air of devotion and quiet strength. In practice, Bronagh is cherished for its warm, melodic sound and its deep connection to Irish heritage rather than for any association with sadness.
Cahal
“Battle ruler, mighty in battle”
Cahal means 'battle ruler' or 'mighty in battle,' reflecting the warrior spirit that was deeply valued in ancient Irish society. It is the anglicised form of the Gaelic name Cathal, combining strength with authority. This is a name rooted in leadership and courage, carrying the weight of centuries of Irish chieftains and kings who bore it.
Cahir
“Battle warrior”
Cahir is the anglicised form of the Old Irish name Cathair, composed of 'cath', meaning battle, and 'fir', meaning man or warrior. Together they form the meaning 'warrior of battle' or 'battle man'. The name has deep roots in ancient Irish kingship, borne by several legendary and historical figures. It also lends its name to the town of Cahir in County Tipperary, where a famous castle stands, adding a strong sense of place to its identity.
Caireann
“Little friend”
Caireann is an ancient Irish feminine name meaning little friend or beloved, derived from the Old Irish word 'cara' meaning friend, with a diminutive suffix. It is a name of legendary significance in Irish history and mythology: Caireann Chasdub, whose epithet means black-curled, was the mother of Niall of the Nine Hostages, the legendary High King of Ireland who is considered the ancestor of the Ui Neill dynasty. The name carries deep historical resonance alongside its gentle, affectionate meaning.
Caitriona
“Pure, clear”
Caitriona is the Irish Gaelic form of Catherine, ultimately derived from the Greek Aikaterine, which is associated with the word 'katharos' meaning pure or clear. The name was brought to Ireland through early Christian veneration of Saint Catherine of Alexandria and became thoroughly naturalised in Irish culture. It has been one of the most consistently used names in Ireland for centuries and carries associations of clarity, integrity, and classical beauty. The actress Caitriona Balfe brought the name to global prominence through her role in the television series Outlander.
Canice
“Handsome, fair one”
Canice is the anglicised form of the Old Irish name Coinneach, meaning handsome or fair one.

Saint Caoimhinn of Glendalough, a sixth-century Irish monk revered across the Gaelic world, made this name one of the most spiritually charged in the Irish tradition. The name's spelling is a touchstone of Gaelic orthographic tradition, showcasing the language's distinct phonological rules.
