Caitlinn is a modern respelling of Caitlin, the anglicized form of Irish Gaelic Caitlín (with a fada on the í), the Irish equivalent of Catherine/Katherine.

Through the cult of Saint Catherine of Alexandria, the Catherine family spread across medieval Europe; in Ireland it settled as Caitlín, later yielding the English familiar Kathleen.
