Irish Baby Names
Explore 280 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.
Tigernach
“Lordly”
Tigernach derives from the Old Irish word tigerna, meaning lord or chieftain. The suffix -ach was a common formative element in Old Irish names, creating an adjectival meaning of lordly or one who is lordly. The name belongs to a class of ancient Irish names that reflected the hierarchical values of early Gaelic society, where the qualities of lordship, command and noble bearing were held in the highest esteem. It was borne by saints and chroniclers who have left a permanent mark on Irish cultural history.
Toirdhealbhach
“Thunder-shaped”
From the Old Irish toirdhealb, meaning shaped like thunder or resembling thunder. The name suggests immense power, authority, and the dramatic force of a storm. Several High Kings of Ireland bore this name, cementing its association with kingship and supreme authority. In anglicised form it gives rise to Turlough and, more loosely, to Terence.
Tomaltach
“Portly and prosperous”
Tomaltach is an ancient Irish name derived from the Old Irish word 'tomalltach,' meaning 'portly,' 'well-fed,' or 'of good substance.' In early Irish culture, being well-fed or stout carried positive connotations of prosperity, good living, and abundance, so this was a name that signaled favorable life circumstances and material wellbeing rather than any criticism. It is a name with deep roots in the Irish annals, carried by kings and warriors.
Treasa
“Strength”
Treasa is the Irish form of Theresa, a name whose origin is debated but is most commonly associated with the Greek 'therizo' meaning to harvest, or alternatively with the island of Thera. In Irish usage Treasa has developed its own sense of strength, reflecting the resilience and character associated with strong Irish women throughout history. The name has been used in Ireland for generations and carries a distinctly Gaelic flavour.
Tuathal
“People-ruler”
Derived from the Old Irish word tuath, meaning people, tribe, or territory, Tuathal carries the sense of a leader who governs his people with authority and communal responsibility. Tuathal Teachtmar was a legendary High King of Ireland whose name appears in medieval annals. The name is deeply embedded in Gaelic historical tradition and carries a noble, ancient quality.
Tuathla
“Ruler of the people”
Tuathla is an ancient Irish name derived from the Old Irish word 'tuath,' meaning 'people,' 'tribe,' or 'territory,' combined with an element suggesting rule or leadership. The compound name thus carries the meaning 'ruler of the people' or 'lord of the territory,' a name that originally expressed high social status and leadership capacity. It is a name from the very deepest layer of the Irish naming tradition, connected to the fundamental social unit of early Irish society.
Turlough
“Instigator, aid-seeker”
Turlough is a bold and distinctive Irish name meaning "instigator" or "aid-seeker," reflecting the spirited, action-oriented nature valued in ancient Irish culture. The name has a rugged, characterful quality and a rich history tied to Irish kings, harpers, and scholars, making it a name of real substance and heritage.
Ughaire
“Cold, wintry one”
Ughaire is an ancient Irish name believed to carry the sense of coldness or a wintry quality, possibly evoking the stark beauty of the Irish landscape in winter. It is a rare and deeply archaic name that connects a bearer to the earliest layers of Gaelic tradition. The name carries a sense of strength and austerity associated with the old Irish warrior culture.
Ultan
“Man from Ulster”
Ultan derives from the Old Irish word for Ulster, the northern province of Ireland, combined with the suffix denoting a person from that place. The name therefore means man of Ulster or one who comes from the north. It was borne by several early Irish saints, most notably Saint Ultan of Ardbraccan, a seventh-century bishop celebrated for his care of orphaned children during a great plague.
Úna
“Lamb, unity”
Úna is one of the oldest and most lyrical of all Irish girl's names, with a meaning that is debated between scholars: some connect it to the Latin 'una' meaning one or unity, while others trace it to the Old Irish word for lamb, suggesting gentleness and purity. It was a name for fairy queens and noble women in Irish mythology and poetry, giving it an otherworldly, romantic quality that has endured across many centuries.
