Madigan is an Irish surname-turned-given name deriving from Ó Madagáin, meaning “descendant of Madagán,” a personal name built on madadh (“hound, dog”) with the diminutive -án.

As a surname, Madigan is long established in Munster, especially County Clare and Limerick, and appears in records with Anglicized spellings such as Madigan and Maddigan; the original Irish form is Ó Madagáin. It entered first-name use in the late 20th and early 21st centuries in North America and Australia, used for all genders but leaning feminine through overlap with Madison and Madeleine. Variants and related forms include Maddigan and O’Madigan; common nicknames are Madi/Maddie and Mads. The name sits comfortably among other Irish surname choices like Finnegan and Sullivan while retaining a distinct, heritage-rich meaning.
