Irish Boy Names

382 namesBoy

Irish boys' names often have Gaelic roots, but many are known today in anglicized forms that reshape the original Irish spelling. Aidan comes from an Irish name meaning little fire, and it has inspired a whole family of modern variants, including Aiden, Ayden, Kayden and Brayden. Liam began as an Irish short form of the Irish version of a Germanic name meaning will and helmet, and Connor comes from an old name linked to a legendary king of Ulster.

Several names on this list began as Irish surnames. Ryan, Nolan, Brody and Quinn all come from family names, and Riley has Irish roots as well, although it also exists as an English surname. Kevin comes from an Irish name meaning gentle birth and is linked to a saint who founded a monastery at Glendalough. Rowan comes from an Irish name meaning little red one, and Bryan is a spelling of a name associated with a famous high king of Ireland.

Irish spelling can be challenging for English speakers, since the original Gaelic forms follow different rules. Many families choose an anglicized version to make pronunciation easier, while others keep the Irish spelling as a link to heritage. If you choose an Irish name, consider which version you prefer and how often your son might need to explain it.
