Meaning & origin

Chassidy is a modern feminine variant of the Irish surname Cassidy, which itself comes from the Gaelic Ó Caiside, meaning 'descendant of Caiside'. The name entered the U.S. baby name charts in 1972 and reached its peak popularity in 1988, when it was ranked 9457th with a 1-in-160,727 rate. Since then, its usage has been falling, reflecting a broader shift away from 1980s surname-inspired names. Chassidy was most common in the 1980s but has not seen a revival. The name is spelled with a 'Ch' rather than the more common 'C', giving it a distinctive look while maintaining the same pronunciation.

Chassidy is a respelled variant of Cassidy, an English surname derived from the Irish surname Ó Caiside, meaning 'descendant of Caiside'. The personal name Caiside likely meant 'curly-haired'. While Cassidy was historically a surname, Chassidy emerged as a feminine given name in the late 20th century, reflecting a trend of using surname-derived names for girls.
