Ceallach is Irish in Origin.

Ceallach is an Irish Gaelic given name from Old Irish Cellach, of debated etymology. Scholars have linked it either to cell/cill “church” (from Latin cella) with the adjectival -ach suffix, or to an early word for “strife, warrior.” Consequently it is variously glossed as “church‑associated,” “war/strife,” or “bright‑headed,” the last being a later folk etymology. The name underlies the very common surname Ó Ceallaigh, anglicized O’Kelly/Kelly.

In early medieval Ireland and Scotland, Ceallach/Cellach was borne by kings and churchmen, including Cellach (Latinized Celsus), Archbishop of Armagh (d. 1129), and several Connacht and Leinster rulers. Spelling varies across periods: Cellach (Old Irish), Ceallach (Modern Irish), with the diminutive Ceallachán > Ó Ceallacháin (Callaghan). Anglicized given‑name forms such as Kellach appear rarely; Kelly is more typical as a surname‑derived forename. Pronunciation approximates “KEL‑akh/KYAL‑akh,” with the final -ch as in Scottish loch.
