Irish Name Generator
This Irish name generator produces authentic combinations of traditional Gaelic first names and classic Irish surnames, drawing from centuries of Celtic naming conventions. Whether you're writing a novel set in Cork, building a Celtic fantasy world, or researching your Irish heritage, the results reflect the genuine phonetic character of the Irish language — with names like Caoimhe, Ciarán, and O'Sullivan sitting alongside lesser-known regional surnames. Irish names carry structural patterns that distinguish them immediately: the O' prefix (descendant of) and Mac/Mc prefix (son of) appear throughout the surname list, while first names often include silent consonants and vowel combinations unique to Gaelic — bh making a V sound, mh softening to W. The generator respects these patterns rather than anglicising them away. You can filter results by gender to get male or female names specifically, or leave it on any to mix both. Adjust the count to generate a shortlist of five or a broader pool of twenty. This is useful when you need a cast of characters, a family tree for a story, or simply want options to compare before committing to one name. Beyond fiction, these names work well for naming Celtic-themed projects, podcasts, bands, or businesses where an Irish identity matters. The combination of familiar surnames like Byrne and Murphy with rarer first names like Fionnuala or Lorcan gives results that feel grounded rather than invented.
How to Use

Tips
- →Generate a large batch of 15-20 names at once — Irish names often look similar until you read them aloud, and volume helps you spot the one that clicks.
- →For female characters in authentic Gaelic contexts, pair the generated first name with a Ní prefix on the surname — Niamh Ní Cheallaigh reads far more genuinely Irish than Niamh Kelly.
- →If you're worldbuilding, mix one well-known surname like Murphy with a rarer first name like Earnán or Lasairfhíona to balance recognisability with distinctiveness.
- →Avoid generating names and then anglicising the spelling — Caitlin and Cáitlín are essentially different names with different cultural weight; keep the original form.
- →For historical fiction set before the 17th century, favour older Gaelic names like Gofraidh, Muirchertach, or Étaín over names that became common only post-Christianisation.
- →When naming multiple characters in the same fictional family, regenerate until you find a surname you like, then lock it and use the generator's first name variety to give each character a unique given name.
FAQ
How do you pronounce Irish names?
Irish follows Gaelic phonetic rules that differ significantly from English. Aoife is EE-fa, Siobhán is shih-VAWN, Caoimhe is KEE-va, and Ciarán is KEER-awn. The combinations bh and mh make a V or W sound, while silent letters are common. Searching the name on Forvo.com gives you native speaker recordings for any name you're unsure about.
What do the O' and Mac prefixes mean in Irish surnames?
O' comes from the Irish 'Ó', meaning 'grandson' or 'descendant of', while Mac means 'son of'. So O'Brien means descendant of Brian, and MacCarthy means son of Carthach. Many families dropped these prefixes during British rule and reclaimed them in the 20th century, which is why you see both Brien and O'Brien as surnames today.
Are these real Irish names or made-up ones?
All names in this generator are authentic traditional Irish and Gaelic names with documented historical or contemporary use. They come from Gaelic mythology, early Christian saints, medieval manuscripts, and modern Irish census data — not invented combinations. Some are common today; others are older names currently experiencing revival in Ireland.
What is the most common Irish surname?
Murphy is consistently the most common surname in Ireland, followed by Kelly, O'Brien, Walsh, and Smith. Regional patterns exist too — Byrne is especially common in Leinster, while Sullivan dominates in Munster. The generator includes both high-frequency surnames and rarer ones to give varied, realistic results.
Can I use these names for a baby?
Absolutely. Many names here — Fionn, Niamh, Ciarán, Aoibhe — are actively used by Irish parents today. If you're outside Ireland, check pronunciation guides before finalising, since names like Saoirse (SEER-sha) or Tadhg (TYE-g) are often mispronounced in English-speaking countries, which some families find worthwhile and others prefer to avoid.
What's the difference between Irish names and Scottish Gaelic names?
Irish and Scottish Gaelic share common roots but diverged over centuries. Some names appear in both traditions — Fionnlagh, Seumas — but spelling conventions differ. Irish tends to use -adh endings where Scottish uses -agh, and vowel spellings vary. This generator focuses specifically on Irish Gaelic names rather than broader Celtic or Scottish variants.
How do I pick a name that sounds authentically Irish rather than generic Celtic?
Authentic Irish names typically use specific letter combinations: ao, ea, bh, mh, dh, gh. Avoid names that feel invented-Celtic, like 'Aelindra'. From this generator, pairing a traditional surname with an O' or Mac prefix against a less-anglicised first name — Cormac O'Driscoll, Bríd Ní Mhurchú — gives strong authenticity. Female surnames traditionally use Ní (daughter of) instead of O'.
Why do some Irish female names use Ní instead of O'?
In traditional Irish naming, women use Ní (unmarried) or Mhic as the female equivalent of O' and Mac. So a daughter of the O'Brien family would be Ní Bhriain. After marriage, the prefix becomes Uí. This system is still used in Irish-speaking communities. Anglicised Irish culture often drops this distinction, using the same surname form regardless of gender.
