About this list
Unique Irish names come in two main varieties. One is Irish names from Ireland's native Irish language, such as Saoirse and Siobhan. These Irish language or Gaelic names tend to be most popular in Ireland itself, though many have emigrated in recent years.
The other brand of unique Irish baby names popular especially in the US are last names used as first names.Irish last names such as Riley and Quinn are technically gender neutral as first names, but they tend to be used more often in the US for girls.
While classic Irish names such as Bridget and Patrick are of course still used in Ireland, the US, and other countries, many parents are more interested today in finding unique, uncommon, rare, and unusual Irish names.
The Irish names here may be more or less unusual and unique depending on where you live. Fiadh and Aoife not going to turn any heads in Dublin, but they'd definitely qualify as unique Irish girl names in the US. And unique Irish boy names from the American point of view, such as Cian or Seanan, are similarly commonplace in Ireland itself.
Here is a large collection of rare, uncommon, unusual, and unique Irish names.
