Kasidey is Irish in Origin.

Kasidey is a contemporary English given name, a creative respelling of Cassidy (pronounced KASS-ih-dee), the Anglicized Irish surname Ó Caiside. The Gaelic root Caiside likely derives from cas, meaning “curly” or “twisted,” yielding the sense “curly‑haired” or “descendant of Caiside.”

In medieval Ulster, the Ó Caiside were noted hereditary physicians and poets, and their name entered English records as Cassidy. Adopted as a unisex given name in the English-speaking world, it rose in late 20th‑century America, trending strongly feminine from the 1990s onward; musical and pop‑culture exposure (e.g., the song “Cassidy”) aided its spread. Variant spellings include Cassidy, Kassidy, Kasidy, Cassidey, Cassady, Cassidi, Kassidi, and Casidy; Kasidey is a rare modern form using the popular K‑initial and ‑ey ending. Nicknames range from Kass/Kas and Kasi/Casey to Sid/Sidie. Cross‑cultural use remains primarily in North America, with modest presence in the UK and Australasia.
