Irish baby girl names come from several layers of Ireland’s naming history. Some are native Irish language names, some come from Old Irish and medieval naming traditions, some belong to Irish mythology, and others are Irish forms of names that entered Ireland through Christianity and wider European naming traditions.
That distinction matters. Niamh is an Irish name meaning “bright” and has a strong connection with Irish mythology, while Saoirse is a modern Irish word name meaning “freedom.” Éabha is the Irish form of Biblical Eve, and Brigid has both Irish historical and Christian significance through Saint Brigid of Kildare.
As a guide to choosing an Irish girl name, it helps to separate Irish language origin, cultural use in Ireland, mythology, and religious history rather than treating every name used in Ireland as an ancient Irish name.
Current Irish naming data also shows how these traditions coexist with newer international choices: according to Ireland’s Central Statistics Office (CSO), Lily was the most popular girls’ name in Ireland in 2025, followed by Éabha, Fiadh, Grace, and Sadie.
What Makes a Name Irish?
“Irish” can describe more than one relationship with Ireland.
A name may be Irish in language, meaning it comes from Irish/Gaeilge or an older stage of the Irish language. Caoimhe, for example, comes from Irish caomh, meaning “dear, beloved, gentle.” Saoirse comes from the Irish word for “freedom,” while Aisling means “dream” or “vision.”
A name can also be Irish in cultural history without being a simple Irish vocabulary word. Brigid belongs to a long Irish tradition connected with both pre Christian Irish mythology and Saint Brigid of Kildare. Siobhán is an Irish form of Jehanne, ultimately connected with the Biblical name John.
For this reason, the strongest Irish baby name lists should identify the specific connection instead of calling every traditional name “Celtic” or “ancient Irish.”
Irish Baby Girl Names Popular in Ireland in 2025
The latest official national data comes from Ireland’s Central Statistics Office. In 2025, the top five girls’ names were Lily, Éabha, Fiadh, Grace, and Sadie. Lily reached first place for the first time in the CSO series, replacing Sophie, which had ranked first in 2024.
| 2025 Rank | Girl’s Name |
|---|---|
| 1 | Lily |
| 2 | Éabha |
| 3 | Fiadh |
| 4 | Grace |
| 5 | Sadie |
| 6 | Emily |
| 7 | Sophie |
| 8 | Olivia |
| 9 | Croía |
| 10 | Éala |
The full CSO dataset records 5,488 different girls’ names among births registered in Ireland in 2025, showing considerable variety beyond the national top ten.
Not every name in this ranking is Irish in linguistic origin. Lily, Grace, Emily, Sophie, and Olivia, for example, belong to broader English or European naming traditions. Éabha, Fiadh, Croía, and Éala have much more direct Irish language connections. That difference is important if the goal is specifically an Irish origin name rather than simply a name currently used in Ireland.
Traditional Irish Girl Names With Strong Language Roots
Niamh “bright”
Niamh is an Irish feminine name meaning “bright.” It is also a major name in Irish mythology: Niamh is associated with the story of Oisín and Tír na nÓg. The name is feminine in Irish usage and is pronounced approximately NEEV in common English descriptions of the Irish pronunciation.
Irish connection: Native Irish name and Irish mythology.
Religious connection: None required; its significance is primarily linguistic and mythological.
Caoimhe “dear, beloved, gentle”
Caoimhe comes from the Irish word caomh, meaning “dear, beloved, gentle.” It is feminine in Irish usage. The common Irish pronunciation is approximately KEE va.
Irish connection: Direct Irish language origin.
Variant: Keeva and Keavy are anglicized forms and should not be counted as separate names when comparing Irish variants.
Saoirse “freedom”
Saoirse means “freedom” in Irish. Unlike some traditional Irish names, it was first used as a given name in the 20th century, so it should not be described as an ancient medieval personal name.
Irish connection: Modern Irish word name.
Usage: Feminine.
This is a useful example of why “Irish” and “ancient” should not be treated as synonyms.
Aisling “dream” or “vision”
Aisling means “dream” or “vision” in Irish. Although the word has older literary significance, its use as a personal name was created in the 20th century.
Usage: Feminine in Irish.
Variants: Aislinn, Ashling and Aislin.
Fiadh “wild” or “wild animal”
Fiadh is a modern Irish feminine name associated with the Irish word for “wild,” “wild animal,” or “deer.” Some references also give “respect” as an Irish meaning, so the safest presentation is to retain the documented lexical range rather than reduce the name to a single English gloss.
Fiadh is also highly relevant to contemporary naming in Ireland: it ranked third among girls’ names nationally in 2025.
Róisín “little rose”
Róisín is a diminutive of Róis or derives from the Irish word rós, meaning “rose.” The name appears in the 17th century song Róisín Dubh.
Usage: Feminine Irish.
Variant: Rosheen is an anglicized form.
Órlaith “golden ruler”
Órlaith comes from Old Irish elements meaning “gold” and “ruler, sovereign, princess,” giving the established interpretation “golden ruler.” The name was borne by several medieval Irish royals, including a sister of Brian Boru.
Variants: Orla, Orlagh and Órfhlaith.
Usage: Feminine.
Sorcha “radiant, bright”
Sorcha means “radiant” or “bright” in Irish and has been in use since the late medieval period. It is also found in Scottish Gaelic.
Usage: Feminine.
Anglicization: It has sometimes been represented as Sarah in Ireland and Clara in Scotland, although these forms should not be treated as identical in every historical context.
Irish Girl Names From Mythology and Legend
Irish mythology provides another distinct naming tradition. These names should be described as mythological or literary, not Christian or Biblical.
Aoife “beauty”
Aoife comes from Old Irish Aífe, derived from oíph, associated with “beauty.” Aoife is the name of several women in Irish legend, including a warrior associated with Cú Chulainn and Scáthach.
Usage: Feminine Irish.
Pronunciation: Approximately EE fa.
Religious connection: None; its significance is rooted in Irish mythology.
Méabh traditional form of Medb
Méabh is the modern Irish form of Medb, the name of the legendary queen of Connacht in the Ulster Cycle. Maeve is the common anglicized form.
Because the original name Medb has a complicated historical development, it is better not to force one simplified English meaning onto Méabh without qualification.
Usage: Feminine.
Cultural connection: Irish mythology and early Irish literature.
Deirdre meaning uncertain
Deirdre comes from the Old Irish name Derdriu, but its original meaning is uncertain. One scholarly proposal connects it with der, “daughter,” but this is not secure enough to present as a definitive translation.
Deirdre is best known through the tragic heroine of Irish legend and later Irish literature.
Usage: Irish and English.
Important guide: Avoid the common claim that Deirdre definitively means “sorrow.” That association comes largely from the tragic story rather than a securely established etymology.
Eimear Irish mythological name
Eimear is the modern Irish form of Emer, the wife of Cúchulainn in Irish legend. The older name’s meaning is uncertain, so it is better presented through its literary and cultural history rather than assigned a questionable fixed translation.
Usage: Feminine.
Cultural connection: Irish mythology.
Éala “swan”
Éala is a modern Irish feminine name derived from Irish eala, meaning “swan.” The accent was added to make the pronunciation closer to Ella.
It is particularly relevant to current Irish naming because Éala ranked tenth nationally among girls born in Ireland in 2025.
Irish Girl Names With Christian and Saintly Connections
Irish naming history has been deeply influenced by Christianity, but an Irish Christian name is not automatically a Biblical name.
Brigid Irish saint and traditional name
Brigid is an Irish form related to Brighid/Brigit. The name has both pre Christian Irish mythological associations and a major Christian association through Saint Brigid of Kildare.
The Irish Catholic Bishops’ Conference identifies Saint Brigid as Abbess and Secondary Patron of Ireland, with her feast celebrated on February 1. She is associated with Kildare, hospitality, almsgiving and care for the sick.
Religious classification: Saint associated, not Biblical.
Variants: Bríd, Brighid, Brigit, Bridget and Bríd are related forms, but they reflect different historical or linguistic traditions.
Éabha Irish form of Eve
Éabha is the Irish form of Eve, the Biblical name associated with the first woman in Genesis.
Usage: Feminine Irish.
Religious classification: Explicitly Biblical through its relationship with Eve.
Éabha is also part of contemporary Irish naming: it ranked second among girls in Ireland in 2025 and was the most popular girl’s name among babies whose parents were both Irish nationals.
Siobhán Irish form of Jehanne
Siobhán is an Irish form of Jehanne, a Norman French form of Jeanne. The deeper name family is connected with John and therefore ultimately has Biblical roots.
Usage: Feminine Irish.
Pronunciation: Several Irish pronunciations exist, but English speakers commonly encounter a pronunciation close to shi VAWN.
Religious classification: Biblical name family through John; the form itself is specifically Irish.
Eilís Irish form of Elizabeth
Eilís is the Irish Gaelic form of Elizabeth, with the related English spelling Eilish used as an anglicized form.
Religious classification: Biblical name family.
Elizabeth appears in the New Testament as the mother of John the Baptist, making the name religiously significant rather than merely a traditional Irish form.
Gobnait Irish saint’s name
Gobnait is a traditional Irish feminine name associated with Saint Gobnait, a medieval Irish saint particularly connected with Ballyvourney in County Cork and with local traditions in Cork, Kerry and other areas.
The name is traditionally feminine in Ireland. Its meaning is often connected with gob, “mouth,” but its strongest cultural value comes from its saintly history rather than a simple English translation.
Irish Names With Direct Word Meanings
Some modern Irish names are especially clear because they come directly from Irish vocabulary.
| Name | Irish Meaning | Main Connection |
|---|---|---|
| Saoirse | “Freedom” | Modern Irish word name |
| Aisling | “Dream; vision” | Irish literary and word name |
| Caoimhe | “Dear; beloved; gentle” | Irish vocabulary |
| Fiadh | “Wild; wild animal; deer” | Modern Irish vocabulary |
| Croía | “Heart” | Modern Irish word name |
| Éala | “Swan” | Modern Irish vocabulary |
| Róisín | “Little rose” | Irish form/diminutive |
| Niamh | “Bright” | Irish vocabulary and mythology |
| Sorcha | “Radiant; bright” | Irish vocabulary |
| Síofra | “Elf; sprite” | Modern Irish word name |
Croía is a particularly modern example. It comes from Irish croí, meaning “heart,” and was used as a given name by Irish mixed martial artist Conor McGregor for his daughter born in 2019.
Síofra means “elf” or “sprite” in Irish and was created as a given name in the 20th century.
Irish Girl Names and Anglicized Forms
Irish naming history includes many pairs where an Irish language name has an English or anglicized form.
| Irish Form | Anglicized / Common Form | Relationship |
|---|---|---|
| Éabha | Eve | Irish form of Biblical Eve |
| Méabh | Maeve | Modern Irish form of Medb |
| Róisín | Rosheen | Anglicized form |
| Siobhán | — | Irish form related to Jehanne |
| Eilís | Eilish | Irish / anglicized forms |
| Bríd | Bridget | Related Irish and English forms |
| Órlaith | Orla / Orlagh | Anglicized variants |
| Aoife | Eve / Eva | Historical anglicizations |
| Úna | Oona / Oonagh | Irish and anglicized forms |
| Aisling | Ashling | Anglicized spelling |
Not every pair is a perfect one to one translation. Aoife, for example, is sometimes anglicized as Eve or Eva, but that does not mean Aoife and Eve have the same etymological origin.
This distinction is important when comparing Irish names because spelling changes can hide the original language.
Irish Spelling, Accents and Pronunciation
Irish names often contain letters and accent marks that can look unfamiliar to English speakers.
The síneadh fada, or acute accent, is particularly important. It appears in names such as:
- Éabha
- Méabh
- Róisín
- Órlaith
- Siobhán
- Bríd
- Saoirse
Ireland’s CSO notes that from 2018 onward its baby name data has captured the síneadh fada and other diacritics, and that spellings with and without the accent can therefore be treated as separate names in the statistical series.
Pronunciation also varies by Irish dialect. Irish has major Ulster, Connacht and Munster dialect areas, so a name may not sound exactly the same everywhere.
Some useful approximations include:
- Niamh: NEEV
- Aoife: EE fa
- Caoimhe: KEE va
- Saoirse: Approximately SEER sha
- Siobhán: Approximately shi VAWN
- Róisín: Approximately ro SHEEN
- Órlaith: Approximately OR la
- Méabh: Approximately MAYV
- Aisling: Approximately ASH ling
For formal publishing, however, pronunciation should be treated as an approximation because Irish pronunciation changes by dialect and speaker. Specialist name references provide IPA transcriptions for many of these names.
Modern Irish Girl Names to Know
The current Irish naming landscape includes both traditional Irish forms and newer names.
Fiadh
Fiadh is now one of the clearest examples of a modern Irish language name with strong contemporary use. It ranked third nationally in 2025.
Éabha
Éabha combines an Irish language form with Biblical history. It ranked second nationally in 2025, showing how an Irish form of an international Biblical name can become strongly established in Ireland.
Croía
Croía is a modern Irish word name meaning “heart.” It ranked ninth nationally in 2025 and was the most popular girls’ name in County Kerry that year.
Éala
Éala means “swan” in Irish and ranked tenth nationally in 2025. Its spelling also illustrates how an Irish word can be adapted into a modern personal name.
Ríadh
Ríadh entered Ireland’s top 100 girls’ names in 2025, rising from 130th place in 2024 to 80th in 2025. It was one of six new female entries into the national top 100.
Choosing an Irish Baby Girl Name
A useful guide is to decide first what kind of Irish connection you want.
For an Irish language name
Consider:
- Caoimhe
- Saoirse
- Aisling
- Fiadh
- Niamh
- Róisín
- Sorcha
- Éala
- Croía
These names have direct Irish language connections, although their historical ages differ.
For Irish mythology
Consider:
- Niamh
- Aoife
- Méabh
- Eimear
- Deirdre
- Órlaith
These names connect more strongly with Irish legend, early literature or historical tradition than with Christianity.
For Christian Irish heritage
Consider:
- Brigid
- Éabha
- Eilís
- Siobhán
- Gobnait
These should not all be classified in the same religious category. Éabha is an Irish form of the Biblical Eve, while Brigid and Gobnait have Irish saintly associations.
For a name currently used in Ireland
The official 2025 data gives a useful starting point:
Lily, Éabha, Fiadh, Grace, Sadie, Emily, Sophie, Olivia, Croía, and Éala were the top ten girls’ names registered in Ireland.
But if your priority is specifically Irish origin, narrow that list further rather than assuming every top ranking name is traditionally Irish.
Irish vs. Scottish Gaelic Names
Irish and Scottish Gaelic are closely related Celtic languages, but they are not interchangeable.
Some names appear in both traditions or have related forms. Sorcha, for example, is used in both Irish and Scottish Gaelic.
Likewise, spellings may look similar while pronunciation and historical usage differ. A name should therefore be labeled Irish, Scottish Gaelic, or both according to its documented usage rather than simply calling every Gaelic name Irish.
This distinction is especially important when researching “Celtic girl names.” Celtic is a much broader cultural and linguistic category than Irish.
FAQs
What is the most popular Irish girl name in Ireland?
According to Ireland’s CSO, Lily was the most popular girls’ name registered in Ireland in 2025. Éabha ranked second and Fiadh third.
What is a genuinely Irish girl name?
Examples with direct Irish language connections include Niamh, Caoimhe, Saoirse, Aisling, Fiadh, Róisín, Sorcha, Órlaith, Éala, and Croía. Their historical periods differ, so “Irish” does not necessarily mean “ancient.”
What Irish girl name means freedom?
Saoirse means “freedom” in Irish. It became a given name during the 20th century rather than being an ancient medieval personal name.
What does Niamh mean?
Niamh means “bright” in Irish. It is also the name of a major figure in Irish mythology associated with Oisín and Tír na nÓg.
Is Éabha a Biblical name?
Éabha is the Irish form of Eve, so it belongs to a Biblical name family. The Irish spelling and pronunciation make it specifically Irish in form, while the underlying personal name is Biblical.
Is Brigid an Irish Christian name?
Brigid has a more complex history. Brigid is an Irish name associated with both Irish mythology and Saint Brigid of Kildare. The saint is recognized as one of Ireland’s important patron saints, so Brigid has a strong Christian association in Ireland, but the name itself should not simply be labeled “Biblical.”
What does Caoimhe mean?
Caoimhe comes from Irish caomh, meaning “dear, beloved, gentle.” It is a feminine Irish name and is commonly pronounced approximately KEE va.
Is Maeve an Irish name?
Yes. Maeve is the common anglicized form of the Irish name family represented by Medb, with Méabh being a modern Irish form. The name is strongly associated with Queen Medb of Connacht in Irish mythology.
What Irish girl name means “heart”?
Croía comes from Irish croí, meaning “heart.” It is a modern Irish feminine name and appeared ninth nationally among girls’ names in Ireland in 2025.
Final Thoughts
Irish baby girl names draw from several distinct traditions: Irish language vocabulary, Old Irish history, mythology, Christian naming, saints, and modern naming in Ireland.
Names such as Niamh, Aoife, Méabh, and Deirdre connect strongly with Irish legend, while Saoirse, Aisling, Caoimhe, Fiadh, and Éala have direct Irish language connections.
Christian heritage adds another layer. Éabha is the Irish form of Biblical Eve, while Brigid, Gobnait, Siobhán, and Eilís connect with Irish Christian or wider Christian naming traditions in different ways.
For parents interested in names actually being chosen in Ireland today, the latest CSO data shows Lily, Éabha, Fiadh, Grace, and Sadie leading the 2025 girls’ rankings.
The best way to choose is to decide if you want a name that is Irish in language, Irish in mythology, Irish in Christian history, or simply established in modern Ireland.
Once that distinction is clear, the meaning, spelling, pronunciation and cultural history become much easier to compare.
