Kallahan is a modern respelling of the Irish surname Callahan, ultimately from the Gaelic Ó Ceallacháin, meaning "descendant of Ceallachán," a diminutive of Ceallach. The root’s sense is debated: many authorities gloss it as "strife, war," others as "bright-headed," and some connect it to ceall, "church," reflecting the name’s long monastic associations. Medieval bearers included Cellachán (Callaghan) of Cashel, a 10th-century king of Munster, and St. Cellach (Celsus) of Armagh, which helped entrench the surname across Ireland.

As a given name, Kallahan follows the recent Anglophone trend of converting Irish surnames into first names and favoring phonetic K-spellings.
