Irish and Celtic Baby Names: Meanings and Pronunciation Guide

They carry the sound of old legends and windswept coastlines, and many of them have meanings that feel like little poems: "little rose", "bright", "freedom" or "little deer". Their spelling can look intimidating at first glance, though. How do you get from Saoirse to SEER-sha, or from Caoimhe to KEE-va?

This guide answers that question. You will find the most beautiful Irish baby names for girls and boys with a simple pronunciation and the meaning of each one. A selection of Scottish and Welsh names completes the list for families who love the wider Celtic world.

How to Pronounce Irish Names: The Basics

Irish (Gaeilge) follows its own spelling rules, which is why names look so different from how they sound. Once you know a few patterns, most names become easy to read.

Spelling	Usually sounds like	Example
bh, mh	v or w	Caoimhe (KEE-va), Niamh (NEEV)
dh, gh	silent or a soft breath, especially in the middle or at the end	Tadhg (TYGE, rhymes with tiger without the r)
s before e or i	sh	Seán (SHAWN), Saoirse (SEER-sha)
ao	ee (in many regions)	Aoife (EE-fa), Caoimhe (KEE-va)
á, é, í, ó, ú	a longer vowel (the accent is called a fada)	Róisín (ro-SHEEN)
c	always a hard k	Ciara (KEER-a), Cillian (KILL-ee-an)

Pronunciation varies between regions of Ireland, so you may hear slightly different versions of the same name. The guides below give the most common modern pronunciation used in Ireland.

About the fada: the accent mark is part of the correct spelling (Seán, Róisín, Oisín). Many parents abroad drop it on official documents. Both choices are perfectly acceptable, but keeping it respects the original name.

Our favorite Irish girl names

Saoirse became widely known abroad thanks to actress Saoirse Ronan. Its meaning, "freedom", carries real weight in Irish history, and the sound is soft and modern.

Niamh is short and luminous. In legend, Niamh of the Golden Hair rides out of the sea to carry the hero Oisín to Tír na nÓg, the land of eternal youth.

Fiadh is a modern favorite in Ireland. It is simple to say once you know the "dh" is silent, and it means "wild" or "deer".

Róisín means "little rose" and appears in the famous poem Róisín Dubh, where the dark rose is a symbol of Ireland itself.

Our favorite Irish boy names

Oisín is the name of the legendary poet who followed Niamh to Tír na nÓg. When he returned to Ireland, three hundred years had passed. The name is gentle and romantic, and it means "little deer".

Tadhg is short and unmistakably Irish. It looks puzzling on paper, but once people hear it said, they remember it.

Cillian has risen sharply abroad, partly thanks to actor Cillian Murphy. The anglicized spelling Killian is common in the US.

Darragh means "oak tree", a symbol of strength in Celtic tradition. It is a popular name in Ireland that still feels fresh elsewhere.

Practice the pronunciation with a native speaker or an Irish language resource, especially for names like Tadhg or Sadhbh.
