Caylan is a modern respelling of the Gaelic given name Caolán (commonly represented in English as Caelan), derived from Old Irish caol, “slender, narrow, fine,” plus the diminutive suffix -án.

Caolán appears in medieval Irish records and was revived in the late twentieth century; the y-inserted spelling Caylan emerged in English-speaking countries during the 1990s–2000s alongside Kayla/Cayla and other -ay/-ae fashions. Usage today is unisex in North America but remains more commonly masculine in Ireland. Notable variants include Caelan, Cailan, Kaelan, Kailan, Kaylan, Cailen/Caelen, and the anglicized Keelan/Kealan; related endings such as -lin or -lyn yield forms like Cailin, Caylin, and Kaylin.
