The 149 Most Popular Celtic Baby Boy Names

If you’re something of a history fan, you’ve probably considered Celtic baby boy names for your son-to-be. Dating back to the sixth century BC, the Celts hailed from Europe and Western Asia, and their culture still remains today. In particular, Celtic languages are spoken in Wales, Scotland, Ireland, France, and even parts of Argentina and Canada. It’s no wonder Celtic male names have stood the test of time. In particular, Irish male names and Gaelic boy names (note the difference – ‘Gaelic’ in isolation refers to Scotland, whereas ‘Irish Gaelic’ is spoken in this region) continue to remain popular today. So, what are some of the best Celtic names for boys?

Celtic baby boy names and meanings

Some recurring themes in Celtic baby boy names are nature, war, and even animals. In particular, you’ll notice a lot of animals in Irish male names, for example:

1. Conor

In Irish Gaelic, the name Conor translates as ‘lover of hounds’ – perfect if you’ve got a pup running around the house! For an even more authentic twist, you could try the Conall variant.

2. Oisin

This one has roots in Irish mythology. Oisin means ‘little deer’ because, legend has it, a warrior named Fionn MacCool witnessed his mother being turned into a deer!

3. Callum

Callum has Latin roots, coming from ‘columba’, which means ‘dove.’
