Killia is Gaelic in Origin.

Killia is a modern, rare given name, most plausibly a feminine elaboration of Killian/Kilian, the Anglicized and German forms of Irish Cillian. Cillian derives from Old Irish Cillín or Cilléne, built on cill “church” with the diminutive -ín, so its core meaning is “little church” or “monastery.” The name entered wider European awareness through Saint Kilian, a 7th-century Irish missionary venerated in Würzburg, which explains the prevalence of the Kilian spelling in German-speaking regions.

Variants and related forms include Killian, Kilian, Cillian, Kilia, Kiliah, and Kylia; nicknames such as Killi or Lia are sometimes used informally. Some sources associate the Cillian/Killian cluster with Old Irish Ceallach “strife, war,” but this is likely a separate name that later became conflated. Killia also echoes Greek kellia “cells,” known from monastic place-names, adding a coincidental spiritual nuance. Overall, Killia blends Irish heritage with a contemporary, lyrical profile.
