Kyllian is a modern French-influenced respelling of Killian/Cillian, ultimately from the Irish Gaelic Cillian (Cillín). Most scholars derive it from cill “church” + the diminutive -ín, yielding the sense “little church” or “devotee.” A minority connect it to the older personal name Ceallach, interpreted as “war/strife” or “bright-headed,” so the meaning is sometimes given in both ways. The name gained renown through the 7th‑century Irish missionary St. Kilian, martyred at Würzburg, which spread it across German-speaking Europe.

Variants include Cillian (Irish), Killian (English), Kilian (German and Central European), and the French modern forms Kylian and Kyllian; feminine elaborations such as Kiliane/Kyliane also occur. Usage revived in Ireland and the Anglosphere in recent decades, with an additional boost in France, where Kylian surged in the 2010s; Kyllian is the rarer, stylistic twin. Pronunciation generally mirrors the base forms: KILL-ee-an or KIL-yən.
