Do you want your baby to have a name that reflects Celtic heritage? These Celtic and Gaelic names come from Ireland, Scotland, Wales, England, and areas of northern Spain. Pronunciation and spelling can be tricky with Celtic names. While some have been fairly common, such as Erin, others are more exotic. Many Celtic names are also used for both boys and girls, such as Sean and Quinn.

The Celts were European tribes who occupied much of Europe north of the Alps in the Iron Age and settled in the British Isles in the fourth to second centuries B.C. Their Celtic languages, including Gaelic, survived the invasions of the Romans, Germanic tribes, and Anglo-Saxons longer in Ireland, Scotland, and Wales. However, Celtic heritage might be celebrated by anyone with ancestors from much of Europe from the Danube to the Rhine and Douro Rivers. Learn the meaning behind the name as you consider what to name your child.

These names have Celtic roots or are the forms used in Celtic lands for names from other roots.
