Meaning and origin
Cassidy means 'Curly-haired' — inherited from the Irish personal name Caiside, built on the Irish word element 'cas' meaning 'twisted, curly'. Cassidy itself is a surname-turned-given-name and has no independent etymology of its own beyond this inherited sense.
Originally an Irish surname (Ó Caiside, 'descendant of Caiside') borne by a family from County Fermanagh who served as hereditary physicians to the Maguire clan; like many Irish surnames, it crossed into first-name use in the United States as part of a broader late-20th-century trend of surname-derived given names.
