Cayleen is English in Origin.

Cayleen is a modern English feminine name likely formed as a variant of Kayleen and Caileen, blending Kay - often a shortened form of Katherine/Catherine - with the melodic -leen ending familiar from Irish-influenced names like Eileen and Colleen. Because of this link to Katherine, the name is commonly interpreted to mean “pure.” Some also see an echo of the Irish word cailín, “girl,” which has influenced several Anglicized names, adding an Irish lilt to Cayleen’s sound.

Usage appears chiefly in North America from the late 20th century onward, part of the broader trend of Caitlin/Kaylin/Caelyn spin-offs and creative spellings. It remains uncommon yet recognizably modern. Close variants and related forms include Kayleen, Kaylene, Caylene, Caileen, Cailene, Caelyn, Caelin, Kaylin, Kailene, and the Irish Caitlín/Caitlin at the root of the family. Parents often choose Cayleen for its gentle rhythm, contemporary feel, and subtle Gaelic flavor.
