81 Irish Baby Names With Pronunciation and Meanings

Irish names are beautiful on the page and in the air, but they do not always sound the way an American reader expects. Saoirse is SEER-shuh, Niamh is NEEV and Tadhg rhymes with “tiger” without the r. Once you learn a few simple spelling rules, these names become much easier to read and to love.

This list gathers 81 Irish baby names for girls and boys, each with a US-friendly pronunciation guide, its meaning and its roots in Irish language, legend or the lives of the saints. You will also find a table of easy-to-spell anglicized Irish names that work for any gender.

Why Irish Names Look So Different From How They Sound

Irish (Gaeilge) uses the Latin alphabet, but the traditional Irish alphabet has only 18 letters and pairs them in ways English does not. A few patterns explain most of the surprises:

• bh and mh usually sound like v (or sometimes w). That is why Caoimhe is KEE-vuh and Siobhán is shiv-AWN.
• dh and gh are often silent or soft in the middle or at the end of a name, as in Fiadh (FEE-uh) and Clodagh (KLOH-duh).
• s before e or i usually sounds like sh, which is why Seán is SHAWN and Sinéad is shin-AYD.
• c is always a hard k sound, so Ciara is KEER-uh, never SEER-uh, in Irish.
• th often sounds like a plain h, as in Cathal (KA-hul).

Irish also follows a rule about vowels known as “slender with slender, broad with broad.” The letters e and i are slender, while a, o and u are broad, and consonants change their sound depending on which kind of vowel sits beside them. That rule is why so many Irish names have vowel clusters like ao, ei and ui that look crowded to English speakers.

Pronunciation also varies across Ireland. The Ulster, Connacht and Munster dialects of Irish can say the same name a little differently, so the guides below give the most common pronunciation heard in the U.S. and Ireland rather than the only correct one.

The Fada: Why That Little Accent Matters

The accent mark you see in names like Róisín, Seán and Áine is called a fada, the Irish word for “long.” It marks a long vowel, and it can change both the sound and the meaning of a word. Without the fada, Seán becomes sean, the Irish word for “old.”

Many Irish families see the fada as part of the correct spelling. In the U.S., though, some state vital records systems and many websites do not handle accent marks well. If you choose a name with a fada, ask your hospital or state vital records office whether it can appear on the birth certificate, and decide how you will write it on school and medical forms.

Irish Girl Names

These girl names range from saints and queens of legend to modern favorites in Ireland like Fiadh, Saoirse and Caoimhe.

Irish Boy Names

Many Irish boy names come from early Irish saints or from the heroes of the Fenian and Ulster tales. Some are also Irish forms of names Americans already know, like Seán for John and Pádraig for Patrick.

Anglicized and Unisex Irish Names

If you want an Irish connection without the spelling challenge, anglicized names are a good fit. Many of them began as Irish surnames with Ó (“descendant of”) or Mac (“son of”) and later became first names in America.

Names From Irish Legend and the Lives of the Saints

Many of the most loved Irish names come from two deep wells. The first is mythology. Fionn mac Cumhaill led a band of warriors called the Fianna, and his son Oisín followed the fairy woman Niamh to Tír na nÓg, the land of eternal youth. In the tale of the Children of Lir, Fionnuala and her brothers Aodh, Fiachra and Conn are turned into swans by their jealous stepmother.

The second well is the early Irish church. St. Patrick (Pádraig) and St. Brigid are Ireland’s best-known patron saints, and St. Brendan is remembered for the legend of his voyage across the ocean. St. Kevin (Caoimhín) founded the monastery at Glendalough, and St. Ciarán founded Clonmacnoise. Names like these give you a story to share with your child as they grow.

Irish names are also part of mainstream American naming. Liam, a short form of the Irish Uilliam (William), was the No. 1 boy name for babies born in 2025 in Social Security Administration data. You can see where other favorites land on our list of popular baby boy names in the U.S..

Irish Names in America vs. in Ireland

Irish names often take a different path in the U.S. than in Ireland. Many Irish American families chose anglicized names or Irish surnames as first names, which is why Riley, Kennedy, Quinn and Casey feel so familiar here. Erin and Shannon, which many Americans think of as classic Irish girl names, have long been used far more often outside Ireland than inside it.

In Ireland, parents have shown growing love for names spelled the traditional Irish way. Names like Fiadh, Saoirse, Caoimhe, Tadhg, Oisín and Cillian are well-loved choices there. If you want a name that feels current in Ireland itself, the traditional spellings in our tables are a good place to start.

Common Spelling Variants for American Parents

Many Irish names have English-friendly spellings that keep the sound but drop the tricky letter combinations. These variants are a practical middle ground if you love a name but want fewer corrections at school:

• Caoimhe is sometimes written Keeva.
• Niamh is sometimes written Neve or Neeve.
• Aodhán became Aidan and Aiden.
• Ciarán became Kieran.
• Cillian is often spelled Killian.
• Ruairí became Rory.
• Seán appears as Sean, Shaun and Shawn.

Keep in mind that the anglicized version can feel less authentic to Irish speakers, and some names, like Saoirse, have no widely used alternative spelling. There is no wrong answer here. Choose the spelling that balances heritage and ease in the way that suits your family.

Traditional Irish Naming Patterns

Genealogists often describe a traditional pattern used by many Irish families in past generations. The first son was commonly named after his paternal grandfather and the first daughter after her maternal grandmother, with later children named for other grandparents, parents and aunts or uncles. That is one reason the same few names, like Patrick, Mary, John and Bridget, repeat so often in Irish family trees.

Few families follow the pattern strictly today, but it can still be a helpful starting point. If you are researching your own Irish roots, look at the names that repeat across generations. You may find a family name worth bringing back in its traditional Irish form.

Tips for Choosing an Irish Baby Name

• Decide on spelling vs. ease. Traditional spellings like Caoimhe honor the language, while anglicized forms like Keeva are easier for others to read. Both choices are valid.
• Practice the pronunciation. Listen to native speakers if you can, and be ready to gently correct teachers and relatives more than once.
• Think about the fada. Check whether your state accepts accent marks and how you will type the name on everyday forms.
• Check the legend. Some heroines, like Deirdre, have tragic stories. Read the tale before you choose.
• Use a middle name. A traditional Irish middle name is a gentle way to honor heritage. Our list of middle names for girls and boys can help with pairing.
• Consider unisex options. Quinn, Rowan and Casey work for any child. See more in our guide to gender-neutral baby names.

Tip: Write the name and its pronunciation on a card for grandparents, teachers and daycare staff. It saves your child from years of corrections.

Bringing an Irish Name Home

An Irish name can carry family history, a love of legend or simply a sound you find beautiful. Start by saying your favorites out loud with your last name, then think about how often you are willing to spell or explain the name.
