What is the meaning of the name Kerrigan ?

Kerrigan is Irish in Origin.

Kerrigan is an Irish surname turned given name, from Gaelic Ó Ciaragáin (“descendant of Ciaragán”), a diminutive of ciar meaning “dark, dusky, black-haired”; hence “little dark one” or “offspring of the little dark-haired man.” The surname clusters in the west of Ireland - especially Mayo and Galway - with pockets in Donegal, and appears in records from medieval annals through 17th‑century muster rolls.

As a first name, Kerrigan emerged in the late 20th century English-speaking world, part of the broader surname-as-given-name trend; in the U.S. it spiked after public attention to figure skater Nancy Kerrigan in the 1990s. Usage is unisex but leans feminine. Spelling variants include Kerigan and Kerrigen; related short forms are Kerry/Kerri. Cognate or root-related names include Ciarán/Kieran and Ciara/Kiera, which share the ciar element but are distinct. The name carries a moody, Celtic meaning linked to dark hair or complexion, balanced by a modern, brisk sound.
