Kassidy is Irish in Origin.

Kassidy is a modern respelling of Cassidy, an Anglicized Irish surname from Ó Caiside, meaning “descendant of Caiside.” The personal name Caiside is often linked to the Gaelic cas, “curly(-haired),” giving the surname - and later the given name - the sense of “curly-haired.” Ó Caiside was borne by a learned medieval family from Fermanagh known for physicians and poets, helping establish the name’s cultural footprint in Ireland before its spread in the Anglophone world.

As a given name, Cassidy rose in late-20th-century North America amid the surname-as-first-name trend, with Kassidy emerging as a K-initial variant favored in the 1990s–2000s. It is unisex but used predominantly for girls today. Related spellings include Cassidy, Cassady, Kasidy, Kassidi, Kassidee, and Cassidey. Short forms and nicknames include Cass, Kass, Cassie, and Kassie. Kassidy keeps the Irish heritage while offering a contemporary, tailored look.
