Irish names are famously difficult for non-Irish speakers — but here's the thing most people don't realize: they're not random. Irish Gaelic has a consistent set of phonetic rules, and once you understand those rules, the names stop looking like puzzles and start looking like what they are: a perfectly logical language with a different set of conventions from English.

The problem is that Irish was nearly destroyed — first by centuries of suppression under British rule, then by the catastrophic population loss of the Great Famine. The language survived, but its phonetic traditions became unfamiliar to most of the world. Today, Irish names are popular internationally, carried by people whose families emigrated generations ago and by parents who simply love the sound of them. But the pronunciation often got lost along the way.

This guide covers the core rules of Irish phonetics and then walks through 35 of the most commonly used — and commonly mispronounced — Irish names. Work through the rules section first. It'll make the names much easier to understand.

The 8 Rules That Unlock Irish Pronunciation

BH / MH
= "V" sound
Siobhán → Shih-VAWN, Niamh → NEEV
DH / GH
= silent or soft "Y"
Tadhg → TIGE, Meadhbh → MAEV
S + slender vowel
= "SH" sound
Siobhán → SH-ivawn, Séan → SHAWN
AO
= long "EE" sound
Caoimhe → KEE-va, Saoirse → SEER-sha
AI / EI
= "AH" or "EH"
Aisling → ASH-ling
Final -E
= short "EH" (never silent)
Aoife → EE-fah, Deirdre → DEER-dreh
CH
= guttural "KH" (like Scottish loch)
Lorcán → LOR-kawn
Fada (á é í ó ú)
= lengthens the vowel
Pádraig → PAW-drig

Girls' Names

Irish girls' names tend to have soft, flowing sounds — a lot of long vowels and gentle consonants. Many come from Irish mythology, nature, or the names of early Christian saints.

1
SiobhánGirl
Syo-bahnShih-VAWN

The most internationally recognized Irish name — and the most mispronounced. "S" before a slender vowel becomes "Sh," and "bh" is always "v." The fada on the final "a" lengthens it to "awn." The Irish form of Joan, it's been a staple of Irish naming for centuries. Say it in one flowing movement: shih-VAWN.

NiamhGirl
Nee-amNEEV

From Irish mythology — Niamh of the Golden Hair was the goddess who brought the warrior Oisín to Tír na nÓg, the Land of Eternal Youth. One syllable only: NEEV. The "mh" at the end follows the standard rule and gives us "v." It means "bright" or "radiant" in Irish.

▶ Hear it pronounced
3
AoifeGirl
A-oh-fay / Ao-ifeEE-fah

Consistently one of the top Irish girls' names. The "ao" combination gives a long "ee," and the final "-fe" follows the rule that the ending "-e" is always voiced as a short "ah." EE-fah. In mythology, Aoife was a fierce warrior queen — the rival of Scáthach. Today it's simply a beautiful, very Irish name.

4
CaoimheGirl
Kow-im-hayKEE-vah

From "caomh" (gentle, beautiful). The "ao" gives us "ee," the "mh" gives us "v," and the final "e" gives us "ah." Three rules in one name. KEE-vah. Despite its intimidating appearance it's a genuinely lovely two-syllable name that flows easily once you know it.

▶ Hear it pronounced
5
SaoirseGirl
Sore-issSEER-sha

Meaning "freedom," this name carries genuine political weight in Ireland — it became popular during the independence movement of the early 20th century. The "ao" gives us "ee," making the first part "seer," and the "-rse" ending becomes "-sha." Actress Saoirse Ronan has brought it to international attention. SEER-sha.

▶ Hear it pronounced
6
AislingGirl
Ay-sling / Az-lingASH-ling

An aisling is a type of Irish-language poem in which Ireland appears to the poet as a beautiful woman. The name carries all of that literary and political weight. The "ai" combination and the following "sl" produce "ash" — ASH-ling. One of the most popular Irish girls' names of the past 30 years, it also appears as Ashling and Aislinn.

▶ Hear it pronounced
7
MeadhbhGirl
Med-hv / Mead-hvMAEV

The original Irish spelling of Maeve — and the version that most reliably defeats non-Irish readers. The "dh" is silent, and the "bh" gives us "v," so the whole name collapses into one syllable: MAEV. Queen Meadhbh of Connacht is one of the great figures of Irish mythology, the warrior queen of the epic Táin Bó Cúailnge.

▶ Hear it pronounced
8
DeirdreGirl
Dee-dreeDEER-dreh

The tragic heroine of "Deirdre of the Sorrows," one of the great stories of Irish mythology. The ending "-dre" follows the Irish rule: the final "e" is voiced as a short "eh," not silent as it would be in English. DEER-dreh, not DEER-dree. It's one of the oldest Irish female names still in common use.

▶ Hear it pronounced
9
GráinneGirl
Grain / Gray-neeGRAW-nyeh

The fada on the "a" lengthens it to "aw," and the "-inne" ending gives us "-nyeh" (a palatalised "n" followed by the standard final "e" sound). GRAW-nyeh. Gráinne is the heroine of the great Irish love story — she fled her arranged marriage with the aging Fionn Mac Cumhaill to elope with the young warrior Diarmuid.

▶ Hear it pronounced
10
BrídGirl
Brid (as in bride)BREED

The Irish form of Bridget, and the name of Ireland's beloved patron saint, Saint Brigid of Kildare. The fada on the "i" lengthens it: BREED, not BRID. Saint Brigid is so central to Irish culture that February 1st — her feast day — was recently made a public holiday in Ireland. The name comes from the old Irish word for "exalted one."

💡 Why are Irish names so different from their spellings?

Irish was an oral tradition long before it was written down. When Christian monks began recording the language in the 6th and 7th centuries, they used the Latin alphabet — but Latin didn't have letters for many Irish sounds. They created combinations like "bh" and "mh" to represent sounds that Latin simply couldn't express. Those combinations have been consistent for over 1,000 years — which is why once you learn the rules, they apply to ancient texts and modern names alike.

Boys' Names

Irish boys' names are often shorter and sharper than the girls' names — many are just one or two syllables — but they carry just as many hidden phonetic surprises.

11
TadhgBoy
Tad-hig / TagTIGE (rhymes with tiger)

Meaning "poet" or "philosopher," Tadhg was one of the most common Irish male names in medieval Ireland. The "dh" between broad vowels gives a hard "g" sound, making the whole name rhyme with "tiger" but as one syllable: TIGE. It's currently one of the fastest-rising Irish boys' names and a favourite of Irish parents who want something distinctly Gaelic.

▶ Hear it pronounced
12
SéanBoy
See-an / SenSHAWN

The Irish form of John. The "S" before the slender vowel "é" becomes "Sh," and the fada tells us the vowel is long — giving us the "aw" sound. SHAWN. It's one of the most common Irish male names internationally, though it's often spelled "Shawn" or "Shane" in anglicized form. The original Irish spelling is straightforwardly logical once you know the rule.

▶ Hear it pronounced
13
PádraigBoy
Pad-raig / Pad-rickPAW-drig

The Irish form of Patrick — the name of Ireland's patron saint. The fada lengthens the "a" to "aw," and the "-aig" ending compresses to "-drig." PAW-drig. Saint Patrick himself was actually a Romanized Briton, not Irish — but the Irish form of his name has become one of the most enduring symbols of Irish identity worldwide.

▶ Hear it pronounced
14
CiaránBoy
See-ar-anKEER-awn

From "ciar" meaning dark or black — likely referring to dark hair or complexion. The "C" before a slender vowel in Irish is a hard "k" sound (not soft like the English "c" in "ceiling"). The fada on the final "a" gives us "awn." KEER-awn. Two early Irish saints bore this name, and it remains popular in Ireland today, sometimes anglicized as Kieran.

▶ Hear it pronounced
15
RuairíBoy
Roo-air-eeROO-ree

Meaning "red king" — from "rua" (red-haired) and "rí" (king). The spelling looks like it should be three syllables but it's just two: ROO-ree. This is because the "-airí" cluster compresses significantly in Irish phonetics. Also spelled Ruarí, Ruairí, or anglicized as Rory. Several High Kings of Ireland bore this name.

▶ Hear it pronounced
16
OisínBoy
Oh-ee-sin / Oy-sinUH-sheen

Meaning "little deer" — a diminutive of "os" (deer). The "O" here is short and unstressed, and the "s" before the slender vowel "í" becomes "sh." The fada makes the vowel long: UH-sheen. Oisín was the great poet-warrior of Irish mythology, son of Fionn Mac Cumhaill, who spent 300 years in the Land of Youth with Niamh of the Golden Hair.

▶ Hear it pronounced
17
FionnBoy
Fee-on / Fy-onFYUN

Meaning "fair" or "white" — referring to light hair or complexion. The "io" combination in Irish gives a sound like "yuh," and the double "nn" closes the syllable sharply: FYUN. Fionn Mac Cumhaill (Finn McCool) is the legendary Irish hero — a warrior, hunter, and poet who led the Fianna, Ireland's mythological band of elite soldiers.

▶ Hear it pronounced
18
CathalBoy
Kath-alKAH-hul

Meaning "strong in battle." The "th" in Irish is not the English "th" sound — it's a soft "h" sound. So "Cathal" is not "KATH-al" but "KAH-hul," with the middle consonant reduced to a breath. It's an ancient Irish name borne by kings and chieftains, and it remains genuinely common in Ireland today despite being almost unknown internationally.

▶ Hear it pronounced
19
DiarmuidBoy
Dee-ar-moo-idDEER-mid

The lover in the great Irish romantic tale of Diarmuid and Gráinne. The "mh" gives "v," but when compressed in speech it can become a brief "m" quality — and the "-uid" ending is simply "-id." DEER-mid. Also anglicized as Dermot. Diarmuid was said to have a love spot on his forehead that made any woman who saw it fall instantly in love with him.

▶ Hear it pronounced
20
LorcánBoy
Lor-canLOR-kawn

A diminutive of "lorc" meaning fierce or silent. The fada on the final "a" shifts it from a flat "can" to a longer "kawn." LOR-kawn. This is the Irish form of the name borne by Saint Laurence O'Toole, the patron saint of Dublin — his original Irish name was Lorcán Ua Tuathail. A name with real historical depth, and one that's growing in popularity again.

Irish Surnames

Irish surnames carry the same phonetic rules as first names — and the same potential for mispronunciation. Many internationally famous surnames are Irish in origin, and their pronunciations are frequently mangled outside Ireland.

21
Ó BriainSurname
Oh Brian / O'BryanOh BREE-in

The original Irish form of O'Brien. The "Ó" prefix means "descendant of," and "Briain" is the genitive form of Brian. The surname descends from Brian Boru — the High King who ended Viking dominance in Ireland at the Battle of Clontarf in 1014. BREE-in, not BREE-an. The surname is one of the most common in Ireland.

▶ Hear it pronounced
22
Ó CadhainSurname
Oh Cad-hainOh KY-in

The "dh" between broad vowels produces a hard "y" quality, and "ain" gives us "in." The surname is anglicized as Coyne or Keane. Máirtín Ó Cadhain was one of the most important Irish-language authors of the 20th century, whose novel "Cré na Cille" is considered the masterpiece of modern Irish prose.

▶ Hear it pronounced
23
Ní MhurchúSurname
Nee Mur-chooNee Vur-khoo

This is how the Murphy surname appears for women in Irish — "Ní" means "daughter of," and the name undergoes lenition (a mutation) when following "Ní," turning the initial "M" into "Mh" (pronounced "v") and the "ch" into the guttural sound from the rules above. Murphy, one of Ireland's most common surnames, sounds quite different in its proper Irish feminine form.

Irish Place Names in First Names

Some Irish names are drawn from place names or geographical features, and carry the same phonetic patterns. These names often sound very different from how their spelling suggests.

24
ÉireReference
Ee-ray / Air-ehAY-reh

The Irish name for Ireland itself — and a name sometimes given to girls. The fada lengthens the "E" to "ay," and the final "-e" follows the Irish rule: it's voiced as "eh." AY-reh. Understanding how "Éire" is pronounced helps with a cluster of related names and words in Irish.

▶ Hear it pronounced
25
BanbhaGirl
Ban-bahBAN-vah

An ancient poetic name for Ireland, from Irish mythology — one of three goddess-queens who gave their names to the island. The "bh" in the middle gives "v": BAN-vah. Rarely used as a given name today but deeply rooted in Irish mythological tradition, and occasionally chosen by parents who want to connect their daughter to that ancient heritage.

Modern & Revival Names

Following decades of decline during the 20th century, Irish-language names have experienced a significant revival. These names blend traditional Gaelic phonetics with modern Irish identity.

26
RéamonnBoy
Ree-a-monRAY-mun

The Irish form of Raymond. The fada on the "é" gives us the "ay" sound, and the "-aonn" ending compresses to "-mun." RAY-mun. It's the name used in Irish broadcasting and public life — RTÉ presenter names are often the Irish-language versions of common international names.

▶ Hear it pronounced
27
LaoiseGirl
Lay-oise / Lao-iseLEE-sha

A rising modern Irish girls' name. The "ao" gives "ee," and the "-ise" ending becomes "-sha" — following the same rule that makes Saoirse end in "-sha." LEE-sha. It's given to girls as a distinctly Irish alternative to Lisa or Louisa. Like several modern Irish names, it follows the ancient phonetic rules while having a contemporary feel.

▶ Hear it pronounced
28
EabhaGirl
Ee-ab-hahAY-vah

The Irish form of Eve. The "Ea" gives an "ay" sound, and the "bh" gives "v" — making this a two-syllable name: AY-vah. As the Irish version of one of the most universal names in Western culture, Eabha is a way for Irish families to use a deeply familiar name in a fully Gaelic form. Currently experiencing a strong revival in Ireland.

ConallBoy
Kon-allKUN-ul

From "con" (hound) and "all" (strong) — meaning "strong wolf" or "strong as a hound." The double "ll" at the end is not elongated as it might be in English or Welsh; it's simply "ul." KUN-ul. Conall Cearnach was one of the great warriors of the Ulster Cycle in Irish mythology. The name is currently popular in both Ireland and Scotland.

SorchaGirl
Sor-chahSUR-uh-khah

Meaning "radiant" or "bright." The "ch" here is the guttural sound — like the Scottish "loch" — and the "or" is closer to "ur." SUR-uh-khah. In English-speaking countries it's often simplified to "SOR-a-kha" which is close enough to be recognizable. The name is the Irish equivalent of Sarah in terms of meaning (both relate to light and brightness).
