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.
Sárán
“Noble excellence”
Sárán derives from the Old Irish word 'sár,' meaning 'excellent,' 'noble,' or 'surpassing.' The diminutive suffix '-án' adds an affectionate, youthful quality to the root, creating a name that means something like 'little excellence' or 'one of surpassing quality.' It is a name that carries quiet confidence and an aristocratic heritage rooted in early Irish culture.
Scáthach
“Shadowy one, she who strikes fear”
Scáthach is a name from Irish mythology meaning 'shadowy one' or 'she who strikes fear,' derived from the Old Irish 'scáth,' meaning shadow or shade. In the mythological tradition, Scáthach is a formidable warrior woman and martial arts teacher who trains the hero Cú Chulainn in the arts of war on the Isle of Skye. Her name reflects both her otherworldly nature and her role as a figure who inhabits the liminal space between the living world and the supernatural realm.

Seannan
“Little wise one”
Seannan comes from the Old Irish 'sen', meaning old or wise, combined with a diminutive suffix to produce the affectionate sense of little wise one or little ancient one. The name was borne by Saint Seannan of Scattery Island, a sixth-century Irish monk who founded a celebrated monastery on an island in the mouth of the River Shannon. The saint's name also gave the River Shannon its name, making Seannan one of Ireland's most geographically embedded names.
Ségán
“Little hawk”
Ségán is believed to derive from an Old Irish root related to the hawk or similar bird of prey, with the diminutive '-án' suffix creating a meaning along the lines of 'little hawk' or 'young hawk.' The hawk held a place of honor in early Irish society, associated with swiftness, keen sight, and noble bearing, making this a name that conveyed admirable qualities in a compact, musical form.
Senan
“Little wise one”
Senan derives from the Old Irish 'sen', meaning old, ancient, or wise, with a diminutive suffix giving the sense of little wise one or small ancient one. The name is most closely associated with Saint Senan of Scattery Island, a sixth-century monk who founded a celebrated monastery on Inis Cathaig in the Shannon estuary. His life combined contemplation, scholarship, and the founding of Christian communities along Ireland's Atlantic coast.
Setanta
“One who knows the way”
Setanta was the birth name of Cu Chulainn, the supreme hero of the Ulster Cycle of Irish mythology. The name is thought to derive from a tribal or geographical designation, possibly connected to the Setantii, a Celtic people of northern Britain, though some scholars interpret it as one who knows the way or one who is guided. As a boy, Setanta journeyed alone to the fortress of King Conchobar and killed the great hound of the smith Culann with his bare hands. He then offered to serve as watchdog in its place until a replacement could be trained, earning the name Cu Chulainn, meaning the Hound of Culann.

In Irish mythology, the river itself is associated with Sionann, a goddess who drowned seeking the salmon of wisdom at Connla's Well, adding a layer of myth and mysticism to the name.
Shea
“Hawk-like, fine”

Sheila
“Heavenly, blind”
Sheila is the anglicised form of Sile, the Irish version of Cecilia, which derives from the Latin Caecilius, related to the word for blind.

In Ireland, Sheila became a widespread and beloved name through the nineteenth and twentieth centuries. In Australia it became so common as a generic term for a woman that it entered everyday slang.

Sibhéal
“God's promise, devoted to God”
Sibhéal is the Irish Gaelic form of Isabel or Sibyl, which derives ultimately from Elizabeth through the Old French Isabelle, carrying the Hebrew meaning of 'my God is an oath' or 'devoted to God.' Imported into the Irish language through Norman French influence following the twelfth-century invasion, the name was fully naturalized into Irish phonology and orthography, becoming distinctively Gaelic in its written form. It is a name of quiet dignity, faith, and long tradition.
Sile
“Pure, heavenly”

The name has been cherished in Ireland since the medieval period and belongs to a family of poetic names that capture natural phenomena. Though it is sometimes offered as an Irish equivalent of Sarah, the two names have entirely separate etymologies and the comparison is one of sound rather than meaning.
Sorley
“Summer voyager”
Sorley is the anglicised form of the Old Irish Somhairle, itself derived from the Old Norse Sumarliði meaning summer voyager or summer warrior. The name was brought to the west coast of Scotland and Ireland by Norse settlers and became thoroughly naturalised in Gaelic culture.

It carries an evocative quality, suggesting seafaring adventure and the meeting of Norse and Irish worlds.

“Pleasant one, well-going wanderer”
Suibhne combines elements meaning pleasant, agreeable, or well-going, and is the name of one of Irish mythology's most haunting and poetic figures, Suibhne Geilt, the king driven mad by the horror of battle who became a wild man of the woods, composing exquisite poetry from the treetops. The name encodes both pleasantness and the tragedy of the untethered spirit.
Tadhg
“Poet, philosopher”
Tadhg is one of the oldest and most storied Irish names, meaning 'poet' or 'philosopher.'

The name carries deep associations with learning, storytelling, and Celtic heritage.
Tadhgán
“Little poet”
Tadhgán is the diminutive form of Tadhg, an ancient Irish name meaning 'poet' or 'philosopher,' with the '-án' suffix adding a gentle, affectionate quality that suggests 'little poet' or 'young bard.'

Tigernach
“Lordly”
Tigernach derives from the Old Irish word tigerna, meaning lord or chieftain.

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.

“Portly and prosperous”
Tomaltach is an ancient Irish name derived from the Old Irish word 'tomalltach,' meaning 'portly,' 'well-fed,' or 'of good substance.'
