Meaning & origin
Kerrigan first appeared on the U.S. baby name charts in 1972, a relatively late arrival for a name derived from an old Irish surname. It saw modest use through the 1990s, then climbed steadily to its peak at rank 4546 in 2012, a year that saw its highest number of births. Since 2013, its trajectory has been falling, reflecting a typical pattern for names that spike from pop culture influence. In its peak decade of the 2010s, Kerrigan was most popular in Illinois, its only top state. Despite its decline, the name retains a distinctive sound, blending the popular 'K' initial with a strong Irish heritage. As of 2025, it is a rare choice given to roughly 1 in every 53,576 girls, maintaining a unique but recognizable feel.
Kerrigan is an Anglicized form of the Irish surname Ó Ciaragáin, which comes from the personal name Ciaragán, a diminutive of Ciaran (from 'ciar' meaning 'dark'). The surname was historically common in County Galway and County Donegal. As a given name, it emerged in the late 20th century, likely influenced by the surname and popularized by the character Kerrigan (the Queen of Blades) in the 1998 video game StarCraft.
