Kailan is English in Origin.

Kailan is a modern unisex given name with several plausible origins. In Irish and Scottish Gaelic, it relates to Caolán (anglicized Keelan), from caol “slender, narrow” plus the diminutive -án, yielding “little slender one.” In English-speaking countries it also functions as a contemporary respelling of Caelan/Kaelan and of Kaylan/Kalen, blending the popular elements Kai and -lan. In Chinese contexts, Kailan can be rendered with different characters, e.g., 凯兰 (“victorious orchid”) or 开蓝 (“open blue”), so the meaning varies by writing.

Usage rose in the late 20th and early 21st centuries alongside Celtic-styled and Hawaiian-influenced names; some parents treat it as a clipped form of Kailani (“heavenly sea”). Variants and related forms include Caelan, Kaelan, Cailan, Kailen, Kaylan, Kalin, Kalen, and Keelan; elaborations like Kailani and Kaylani also occur. The name is typically pronounced KAY-lən or KYE-lən, with Kai a common nickname.
