Callan is an Irish and Scottish surname, and a town name in County Kilkenny, of uncertain meaning. It is sometimes linked to Gaelic words for "rock" or "noise", or to the given name Cathalán, a diminutive related to Cathal, a name often rendered "strong in battle", but none of these origins is certain. As a first name Callan fits the popular group of Celtic-sounding names such as Declan and Kellan. It sounds crisp, friendly and modern while resting on a genuine older surname.
