Finnigan is an Anglicized Irish surname-turned-given-name from Gaelic Ó Fionnagáin, “descendant of Fionnagán”; Fionnagán is a diminutive of Fionn, meaning “fair, bright” or “fair‑haired.” Thus the name carries the sense “descendant of the little fair one” and, by extension, “little fair/bright one.”

As a family name it is documented across Ireland from medieval records; as a first name it rose in the late 20th and early 21st centuries in the U.S., Canada, the U.K., and Australia, riding the appeal of the short form Finn. Cultural echoes include James Joyce’s Finnegans Wake and the folk song “Michael Finnegan.” Common spellings and related forms are Finnegan (most prevalent), Finegan, Finigan, and Finnigan; Gaelic Fionnagán and Ó Fionnagáin appear in historical sources. Nicknames include Finn and occasionally Egan; cognate or thematic relatives include Fionn, Finnian, and Finlay/Findlay.
