Ireland's naming tradition draws on mythology, nature and the early Christian saints. These names range from ones already beloved across the UK to hidden gems waiting to be discovered.

---

Irish Baby Names for Boys

Irish boy names often evoke warriors, kings and saints — with a warmth and energy that makes them feel anything but stuffy.

---

Scottish Gaelic Baby Names for Girls

Scottish Gaelic Baby Names for Boys

From Highland clans to Lowland saints, Scottish boy names have a bold, grounded quality.

---

Welsh Baby Names for Girls

Welsh names have a musical, vowel-rich quality unlike any other Celtic tradition. They can sound unfamiliar at first, but many are surprisingly easy once you hear them — and they're having a real moment.

---

Welsh Baby Names for Boys

Tips for Choosing a Celtic Name for Your Baby

Consider the pronunciation. Many Celtic names look more complex than they sound — once you've heard Aoife or Saoirse spoken aloud, they feel completely natural. If you live outside Wales, Ireland or Scotland, a quick pronunciation note for family members goes a long way.

Think about the everyday. Names like Finn, Orla, Rhys, Seren and Callum have crossed into mainstream UK use and won't need explaining at every nursery drop-off. Names like Fionnuala, Tadhg or Taliesin are stunning but do come with a lifetime of spelling it out — which many families love.

Check the nickname potential. Catriona becomes Cat or Cate. Fionnuala becomes Finn or Nuala. Alasdair becomes Al or Ally. A long Celtic name often comes with brilliant built-in nicknames.

Think about siblings. Celtic names tend to work beautifully together — Eilidh and Callum, Seren and Rhys, Aoife and Ciarán all feel harmonious without being matchy-matchy.

FAQ

Are Celtic names popular in England?

Yes — and increasingly so. Names like Finn, Orla, Niamh, Rhys, Seren, Callum and Quinn are all well-established in English schools and nurseries. More distinctly Celtic names like Aoife and Eilidh have also grown significantly in England, helped along by familiar pronunciation guides and cultural awareness. You're unlikely to raise an eyebrow with most of the names on this list, even in areas with no Celtic heritage.

How do I know how to pronounce a Celtic name?

The best approach is to listen — YouTube, Forvo and name pronunciation websites are excellent. Many Irish and Welsh names follow consistent phonetic rules once you learn them (Irish "bh" = "v", Welsh "ll" = a breathy "thl" sound). It's also worth noting that anglicised spellings exist for many names if you want the sound without the complexity — Keeva for Caoimhe, Shawn for Seán, Owen for Owain.

Are Irish and Scottish Gaelic names the same?

No, though they share roots. Both descend from Old Irish, but Scottish Gaelic diverged significantly over the centuries. Some names appear in both traditions — Niall, Sorcha, Fionnuala — while others are distinctly one or the other. Irish names tend to use fadas (accent marks like á, é, í), while Scottish Gaelic uses grave accents (à, è, ì).

What's the difference between Welsh Celtic names and Irish/Scottish ones?

Welsh is a Brythonic Celtic language (descended from ancient British), while Irish and Scottish Gaelic are Goidelic Celtic languages — they're genuinely different branches of the family tree. Welsh names have a distinct sound and spelling system, with double letters like "ll", "ff" and "rh" giving them their musical quality. They're not related to Irish names, but they share that same Celtic spirit.

Can I use a Celtic name if I have no Celtic heritage?

Absolutely. Names travel, and they always have. Celtic names are part of the shared cultural heritage of these islands and are used and loved by families of all backgrounds across the UK. The most important thing is that you love the name and feel confident using it.

Will my child struggle with a Celtic name in England?

Mild mispronunciations will happen — that's true of any less common name. Most families find that a quick "it's pronounced..." note sorts things out permanently, and many parents of children with Celtic names say the name becomes a lovely talking point rather than a problem. Names like Saoirse and Aoife that seemed unfamiliar a decade ago are now widely recognised thanks to film, TV and sport.
