Ceallachan is Irish, Irish (Gaelic) in Origin.

Ceallachan (Irish: Ceallachán) is a medieval Gaelic masculine name formed from Ceallach with the diminutive -án. It appears in 10th‑century annals borne by Cellachán of Cashel, king of Munster and foe of the Norse, and the root name Ceallach was common among early Irish ecclesiastics, including Saint Ceallach (Latinized Celsus), archbishop of Armagh (d. 1129). From it developed the hereditary surname Ó Ceallacháin, widely Anglicized O’Callaghan/Callaghan; as a given name, Ceallachán is rare today but sometimes revived, while Callaghan/Callahan occasionally serve as modern forenames.

The underlying meaning is debated. Ceallachán literally means “little Ceallach,” and Ceallach is variously explained as deriving from Old Irish cellach “strife, war,” from ceall “church/monastic cell,” or from ciall “sense, reason.” Consequently interpretations range from “little warrior” to “little churchman,” though scholarly consensus remains cautious. Variants include Ceallachán, Ceallachan (no fada), older Cellachán, and related Ceallach (Cellach); Anglicized forms are Callaghan and Callahan.
