Irish Boy Names

Irish male names come primarily from the Irish language (Gaeilge), often preserved from Old and Middle Irish. A common masculine structure is the diminutive -án (seen historically in Aodhán, source of Aidan), and many names are built from elements like Áed/Aodh “fire” and Óengus/Aengus. Latinized or Anglicized forms appear in records, with diacritics frequently dropped in modern use. Christian influence is strong through early saints and kings.

Today, both Irish and Anglicized spellings are used in Ireland and abroad. Widely used examples include Aidan, Aiden, Aengus, Aonghus, Aindreas, Aindriu, Ailbe, Aoidh, Aodha, and Aodhfinn.
