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.
Oisin
“Little deer”
From the Old Irish os (deer) with the diminutive suffix -in, meaning little deer. In Irish mythology, Oisin was the son of Fionn mac Cumhaill and Sadhbh, who had been transformed into a deer, making the name both tender and mythologically rich.
Oonagh
“Lamb, unity”
Oonagh is an anglicised spelling of the Irish name Una, which derives either from the Old Irish word uan, meaning lamb, or from the Old Irish word for unity and one. Both possible origins give the name a quality of gentleness and coherence, suggesting something soft and whole. In Irish mythology, Oonagh was the queen of the fairies, the supernatural consort of Finvarra, king of the Connacht fairies, a figure of otherworldly beauty and wisdom.
Oran
“Little pale green one”
Oran is the anglicised form of the Old Irish Odhran, derived from odhra meaning dun-coloured, pale, or sallow, with the diminutive suffix -an. The full meaning approximates to little pale one or little dun-coloured one, likely referring to a fair or pale complexion. Saint Oran, or Odhran, was one of the twelve monks who accompanied Saint Columba on his legendary voyage from Ireland to the island of Iona off the coast of Scotland in the sixth century. He is said to have been the first of the community to die on Iona and is buried in the ancient Reilig Odhrain, the royal cemetery where many kings of Scotland, Ireland, and Norway were interred.
Orla
“Golden princess”
Orla means 'golden princess' in Irish Gaelic, combining the elements for 'gold' and 'sovereign.' It is a name that shines with warmth, nobility, and the particular glow of Irish heritage.
Orlaith
“Golden princess”
Orlaith combines the Old Irish or, meaning gold, with flaith, meaning sovereignty, princess, or ruler. The name therefore carries the literal meaning of golden sovereign or golden princess. It was borne by several figures of early Irish history and mythology, including a sister of the hero Fionn mac Cumhaill. Orlaith is the original and more classical Gaelic spelling of Orla, which has become one of the most fashionable Irish girls' names in recent years.
Oscar
“Friend of deer”
From the Old Irish os (deer) and cara (friend), giving 'friend of deer' or 'deer lover'. In Irish mythology, Oscar was the grandson of Fionn mac Cumhaill and one of the greatest warriors of the Fianna.
Ossian
“Little deer”
Ossian is the Latinised and internationally recognised form of the Irish name Oisín, built on the Old Irish word 'os' meaning deer, with a diminutive suffix giving the sense of 'little deer' or 'young deer'. In Irish mythology, Oisín was the son of the great hero Fionn mac Cumhaill and the goddess Sadhbh, who had been transformed into a deer by a druid's curse. Oisín became the greatest poet of the Fianna and was taken to the Land of Eternal Youth by Niamh of the Golden Hair, making him one of the most romantically tragic figures in all of Celtic literature.
Padraig
“Nobleman, person of noble birth”
Pádraig is the Irish Gaelic rendering of the Latin name Patricius, which carries the meaning of 'noble' or 'patrician', a member of the Roman aristocratic class. The name entered Irish culture through the immense influence of Saint Patrick, the fifth-century missionary whose legacy shaped Christianity across Ireland. It has been borne by countless Irishmen through the centuries and carries the full weight of Ireland's Gaelic Catholic heritage.
Pádraigín
“Little Patrick or little noblewoman”
Pádraigín is a feminine Irish diminutive formed from Pádraig, the Irish form of Patrick, with the feminine diminutive suffix '-ín' added to create a girl's name meaning little Patricia or little noblewoman. The name of Patrick derives from the Latin Patricius, meaning nobleman or of noble birth. Pádraigín thus combines Ireland's most iconic name with the affectionate intimacy of the Irish diminutive tradition.
Peadar
“Rock”
Peadar is the Irish Gaelic form of Peter, which comes from the Greek 'Petros' meaning rock or stone. The name carries the symbolic weight of solidity, reliability, and enduring strength. As the Irish equivalent of one of the most important names in Christian tradition, Peadar connects its bearer to both the Apostle Peter and to a rich heritage of Irish-language culture and literature.
Peig
“Pearl”
Peig is the Irish diminutive form of Peg or Margaret, ultimately derived from the Greek 'margarites,' meaning pearl. In Ireland, Peig took on a life entirely its own, associated especially with the remarkable storyteller and memoirist Peig Sayers of the Great Blasket Island. The name carries a sense of rugged coastal beauty, oral tradition, and the resilience of Irish-speaking communities on the western seaboard.
Pól
“Small or humble”
Pól is the Irish Gaelic form of Paul, derived from the Latin Paulus, meaning small or humble. It entered Irish use through Christianity, specifically through the veneration of Saint Paul the Apostle, and was adapted to fit Irish phonological patterns. The name carries the same spiritual and historical weight as Paul internationally, but with a distinctly Gaelic identity that connects it to Ireland's Irish-language tradition.
Proinséas
“Free man or Frenchman”
Proinséas is the Irish Gaelic form of Francis, a name derived from the Latin Franciscus, meaning Frenchman or free man. The name entered Ireland through Christianity, most powerfully through the influence of Saint Francis of Assisi, and was adapted into Irish with characteristic Gaelic phonological shaping. It carries connotations of freedom, simplicity, and spiritual generosity inherited from its Franciscan associations.
Proinsias
“Free man”
Proinsias is the traditional Irish Gaelic form of Francis, which derives from the Medieval Latin Franciscus, meaning Frenchman or free man. The Franciscan meaning of free man comes from the Germanic word frank, referring both to the Frankish people and to the concept of freedom. In Ireland, Proinsias served as the native language equivalent of Francis and was used to honour Saint Francis of Assisi as well as to carry on family names. It has a scholarly, distinctly Gaelic character that sets it firmly apart from the Latin original.
Quinn
“Wise, chief”
Quinn derives from the Irish surname O Cuinn, meaning descendant of Conn. The name Conn is thought to derive from an Old Irish word meaning chief, sense, or wisdom, giving Quinn its associations with leadership and intelligence. From a hereditary surname tied to one of Ireland's ancient ruling families, it has evolved into a modern given name that carries an easy, confident energy.
Ráichéal
“Ewe, innocent lamb”
Ráichéal is the Irish Gaelic form of Rachel, carrying the same Hebrew meaning of 'ewe' or innocent lamb, a symbol of gentleness, purity, and nurturing grace. Adopted into the Irish language through biblical and ecclesiastical channels, the name acquired an Irish phonological and orthographic identity while retaining its deep scriptural resonance. It is a name that bridges the Hebraic biblical world and the Irish linguistic tradition.
Réaltín
“Little star”
Réaltín is a diminutive of the Irish word 'réalt,' meaning star, with the affectionate diminutive suffix '-ín' giving it the sense of little star or starlet. It is a poetic and tender name that captures the Irish tradition of using celestial imagery in personal names. The name evokes brightness, wonder, and a gentle luminosity that makes it a particularly enchanting choice for a girl.
Rían
“Little king, kingly”
Rían is an Irish boy's name formed from 'rí,' the Old Irish word for king, combined with the diminutive suffix '-án,' giving the sense of little king or one who is kingly by nature.

Compact and easy to pronounce, Rían has a modern, accessible feel while carrying deep traditional weight.
Rioghnach
“Queenly, royal woman”
Rioghnach derives from the Old Irish word 'rígan,' meaning queen or royal woman, and carries a deeply regal sense of dignity and nobility. The name evokes images of ancient Irish sovereignty, a woman who commands respect not through force but through innate grace and authority. It is a name steeped in the spiritual and political traditions of early Ireland, where queenship was bound to land, lineage, and divine favor.
Ríoghnán
“Little king, young ruler”
Ríoghnán is a masculine Irish name derived from 'rígan,' an Old Irish term related to the concept of kingship and royalty, with the diminutive suffix '-án' adding the sense of young or little, producing a name that conveys a young, emerging king or one of kingly character. It is a rare and distinguished Irish name that has been borne historically by figures of noble descent and carries an air of quiet, confident authority.

Rory
“Red king”
Rory is the anglicised form of the Old Irish name Ruairi, meaning red king, from the elements 'rua' (red) and 'ri' (king). Rory O'Connor was the last High King of Ireland, reigning at the time of the Anglo-Norman invasion in the twelfth century. Though traditionally a masculine Gaelic name, Rory has increasingly been embraced as a unisex name in the English-speaking world, known for its bright, energetic sound.
Rowan
“Little red-haired one”
Rowan derives from the Irish surname O Ruadhain, meaning descendant of the little red-haired one, from ruadh meaning red and the diminutive suffix. It is also powerfully associated with the rowan tree, which held deep mystical significance in Celtic traditions as a tree of protection against enchantment and evil spirits. This dual etymology, linking the name to both fiery hair and a magical tree, gives Rowan a richly evocative quality.
Ruadh
“Red-haired”
Ruadh is an ancient Irish Gaelic word meaning red or red-haired. In early Irish culture, red hair was distinctive enough to become a primary identifier, and Ruadh was used as both a descriptive epithet and a given name for those with fiery locks. The name connects to a broader Celtic colour-naming tradition and carries a strong sense of Irish authenticity and antiquity.
Ruairi
“Red king”
Ruairi comes from the Old Irish 'rua', meaning red or red-haired, and 'ri', meaning king, giving the name the striking meaning of red king. Red hair was a mark of distinction and sometimes of divine favour in early Irish tradition, and the combination with kingship makes Ruairi a name of considerable regal and poetic force. It was borne by some of the most significant kings in Irish history, giving it an authenticity that few names can claim.
Sadhbh
“Sweet, goodly”
Sadhbh is a deeply rooted Irish name meaning sweet or goodly, carrying with it one of the most beautiful stories in Irish mythology.

“Free princess”
