What Are Irish Boy Names?

Irish boy names are male first names from the Irish (Gaelic) language or used for generations in Ireland. Many are Gaelic originals. Others are English versions that became part of Irish life over time.

Spelling is the tricky part. The Gaelic form of Eoghan looks nothing like the English Owen, yet it’s the same name. 😄

Here is a quick way to sort them:

• Gaelic originals: Oisín, Tadhg, Cathal
• Anglicized forms: Conor, Declan, Kieran
• Surname-style names: Quinn, Flynn, Brody

These names are easy to say and spell, so they’re a safe pick for everyday life. 👍
