Irish Baby Names
Here’s a list of Irish baby names, with a focus on names that are still alive in Ireland. There are hundreds more unique baby names in the Irish language, but we've passed over those that have fallen out of use.
The bolded version on top of each listing is the one that seems most popular in Ireland now -- that's sometimes an old Celtic name and sometimes a modernized version. It’s followed by other versions used in Ireland, with a pronunciation key.
Where historians disagree on the origin or translation of an Irish baby name, we’ve included several possible definitions (translations are from old Irish/Gaelic). If you think one is wrong, or you want to add some unique baby names that are Irish, please contact me.
