Calihan is an uncommon yet distinctive given name of Irish origin, derived from the Irish surname Ó Ceallaigh, which means "descendant of Ceallach." This name has been predominantly used as a surname in Ireland but has begun to appear more frequently as a first name in recent years, particularly in North America. The name Calihan is associated with several notable figures, including American basketball coach and broadcaster Doug Collins, who goes by the nickname "Calihan." Despite its relative rarity, Calihan is an appealing choice for parents seeking a unique yet meaningful name for their child.
