If there’s one thing the Irish do well (aside from storytelling, fighting over football, and making whiskey), it’s naming things in ways that make absolutely no sense to outsiders.

So if you’re looking for Irish Gaelic names (girl or male), old Irish names, unusual Irish girl names, or just a name that carries the weight of a thousand years, let’s get into it.

What Is the Name for Irish Gaelic?

The language of these names isn’t just called “Irish”—it’s Gaeilge.

Strong names don’t just sound powerful—they carry the weight of generations.
