Caoilfhinn is Irish in Origin.

Caoilfhinn is an Irish Gaelic given name composed of caol “slender, fine” and fionn/finn “fair, bright.” With fh silent, it is commonly pronounced KEE-lin, yielding the Anglicized form Keelin. The sense combines the physical epithet “slender” with the Gaelic poetic ideal of fairness or brightness, often interpreted as “slender and fair(-haired).”

Documented in medieval Gaelic records, the name and its more prevalent spelling Caoilfhionn were borne by women in Ireland and later revived during the 20th‑century Gaelic revival. Variant spellings include Caoilfhionn, Caoilfionn, and the simplified modern Irish Caoilinn; English forms include Keelin and, less precisely, Keelan. Usage today remains strongest in Ireland and across the diaspora, valued for traditional roots and an approachable sound. Related names sharing elements are Fionn and Fionnuala (“fair”), and the male Caolán (“slender”).
