Meaning & origin
Caitrin is an Irish variant of Catherine that first appeared in U.S. birth records in 1976. The name saw a modest popularity peak in 1986, though it never reached the top 1000 ranks and has since remained consistently stable in occurrence. As of the latest year 2025, the name continues to be a rare choice, with no noticeable resurgence in recent decades. Its strength lies in its Irish heritage and the classic, enduring appeal of its root meaning, 'pure'.
Caitrin is an Irish variant of Katherine, which ultimately derives from the Greek name Aikaterine. The name was borne by early Christian saints, including Saint Catherine of Alexandria, and has been used in Ireland since the Middle Ages. It is often anglicized as Catherine or Kathleen.
