Callough is Irish in Origin.

Callough is a rare Anglicised given name most plausibly linked to the Old Irish personal name Ceallach (Latinized Cellachus), long borne in medieval Ireland. The underlying meaning is debated: many sources gloss it as “bright-headed,” while others trace it to a root denoting “strife/war” or to associations with church life (“churchman,” from ceall, ‘church’). That ambiguity is typical of early Gaelic names and allows layered interpretations.

Attested as Cellach/Kellach in annals and among saints and bishops - most notably St. Cellach of Armagh (12th century) - the name later gave rise to the widespread surname Kelly (Ó Ceallaigh) and to Callaghan/Callahan via the diminutive Ceallachán. Callough surfaces in modern English as a rare variant shaped by -ough spellings familiar from Irish surnames. Close forms include Ceallach, Cellach, Kellach, Kellagh and Callagh; short forms Cal and Cally occur. Contemporary use is uncommon but growing, generally masculine though sometimes unisex.
