Hannigan is an Irish surname, a variant of O'Hannagain. The name originates from the Irish Gaelic Ó hAnnagáin, meaning "descendant of Annagán." The personal name Annagán is a diminutive of Annadh, which translates to "delay" or "slowness." Thus, the surname Hannigan carries the connotation of being a descendant of a person associated with delay, though in ancient contexts such names often had neutral or affectionate undertones.
The name is primarily found in Ireland, particularly in counties Cork and Kerry, reflecting its origins in the Gaelic chieftaincies of Munster. Over time, variants such as Hanegan, Hanigan, Hannigen, O'Hanegan, O'Hanigan, and O'Hannagain have emerged among English-speaking diaspora populations.
Notable bearers of the surname include Alyson Hannigan, best known for her roles in the television series Buffy the Vampire Slayer and How I Met Your Mother; Barbara Hannigan, a renowned Canadian soprano and conductor; Ben Hannigan, an Irish footballer; and Dominic Hannigan, an Irish Labour Party politician. Other figures include Ed Hannigan, an American comic book creator, and James Hannigan, a British composer.
