Keiron

Meaning & origin

Keiron is a masculine Irish name that appeared on U.S. birth records starting in 1970. While it has never entered the top 1000 (rank is null for 2025), the name saw its peak usage in 2011. Since 1996, Keiron's trajectory has been steadily falling. The name is concentrated primarily in areas with Irish heritage, though no single state shows overwhelming prevalence (top states are empty in the dataset). As a spelling variant of the more common Kieran or Ciaran, Keiron offers a distinctive yet recognizable choice for families honoring their Irish roots. Its meaning, tied to the Irish 'ciar' for 'dark', connects it to a lineage of early Irish saints and centuries of tradition in Ireland and among the Irish diaspora.

Keiron is generally regarded as an Anglicized variant of the Irish name Ciarán, derived from the Gaelic element 'ciar' meaning 'dark' or 'black', combined with a diminutive suffix. The name has been borne by several early Irish saints, including Saint Ciarán of Saighir (one of the twelve Apostles of Ireland) and Saint Ciarán of Clonmacnoise. In modern English usage, the spelling Keiron is less common than Kieran or Ciaran, but remains known in Irish diaspora communities.
