Calian is a modern name without a settled etymology, usually read as a blend of Callan and Julian or as a respelling of the Irish Cillian, "little church" or "bright-headed". It fits the current taste for soft two-syllable boys' names ending in -ian. In the United States Calian was almost unheard of until it jumped to number 1986 in 2021; it ranks at number 2844 in 2025 with 44 births.
