Irish Name Generator
Authentic Irish first names and surnames
Generate real Irish names, from everyday favourites like Aoife Murphy and Cian O'Brien to fully Gaelic forms such as Tadhg Ó Súilleabháin and Niamh Nic Cárthaigh. Ideal for characters, family-history fiction, fantasy settings with a Celtic flavour, or finding your own Irish name.
About Irish names
Irish names carry two spellings at once. Most given names have an Irish-language form and an anglicised twin: Aoife and Eva, Tadhg and Tim, Séamus and James, Sinéad and Jane, Eoghan and Owen. The fada (the accent on á, é, í, ó, ú) marks a long vowel and changes the sound, so Seán is "shawn" while Sean without it would rhyme with "seen". Intimidating-looking spellings follow consistent rules: "bh" and "mh" sound like v or w, "dh" and "gh" are soft, and "Siobhán" is simply shiv-AWN.
Surnames are built from the Gaelic prefixes Ó ("grandson/descendant of") and Mac ("son of"), which English records turned into O' and Mc or Mac. In Irish, women's surnames change too: a daughter of Ó Briain is Ní Bhriain, a daughter of Mac Cárthaigh is Nic Cárthaigh. Norman families who arrived in the 1100s left Fitzgerald, Burke, Power and Roche, and some names are tied to regions, with O'Sullivan and McCarthy thick in Cork and Kerry, Gallagher and O'Doherty in Donegal.
A believable Irish name matches form and setting. A Dublin office worker reads as Ciara Ryan, a character in a Gaeltacht village or a Celtic-flavoured fantasy as Caoimhe Ní Mhurchú, and a 1900s emigrant as Bridget Coyle. Mixing a fada-heavy first name with a plain English surname is normal in modern Ireland.
How to choose Irish names
- Pick one register and stay in it: Irish-language forms (Ó Súilleabháin, Ní Bhriain) for Gaeltacht, historical or fantasy settings, and anglicised forms (O'Sullivan, O'Brien) for contemporary characters.
- Remember that Ní and Nic are for women and Ó and Mac for men in Irish-language surnames; in English, O' and Mc are used by everyone in the family.
- Check pronunciation before you commit: Saoirse is SEER-sha, Tadhg is like "tiger" without the r, Caoimhe is KWEE-va, and Oisín is uh-SHEEN.
- For a fantasy Celtic world, lean on the older, mythic names such as Gráinne, Deirdre, Fionn, Oisín, Naoise and Sadhbh rather than modern favourites like Conor or Kevin.
- Do not give every character a Murphy or a Kelly; quieter real surnames like Tangney, Brosnan, Lynskey or Geraghty make a cast feel lived-in.
Frequently asked questions
What is the difference between O', Mac and Ní in Irish names?
Ó (anglicised O') means "grandson" or "descendant of" and Mac (Mc) means "son of". In the Irish language a woman uses Ní instead of Ó and Nic instead of Mac, and the following name usually softens: Ó Briain becomes Ní Bhriain. In English these distinctions disappear and the whole family is O'Brien.
What are the most common Irish surnames?
Murphy, Kelly, O'Sullivan, Walsh, Smith, O'Brien, Byrne, Ryan, O'Connor and O'Neill head the list. The generator mixes the Irish names among these with regional and rarer ones such as Brosnan, Tangney, Heffernan and Moriarty, Ulster names like McCloskey and Norman families like Purcell, so you are not handed the same five surnames every time.
Can I use these names for a fantasy character or world?
Yes. Irish is the source of many Celtic-flavoured fantasy names already, and the Gaelic-spelled forms with Ó, Mac and Ní read especially well in a medieval or mythic setting. Pair older names like Gráinne, Naoise or Fiachra with Irish-language surnames for the strongest effect.
How do I find "my" Irish name?
Most English names have a recognised Irish equivalent: John is Seán, Mary is Máire, William is Liam or Uilliam, Catherine is Caitríona, and surnames follow the Ó and Mac patterns above. Browse the generated names for the Irish form of your first name, then attach your own surname in its Gaelic spelling.
