Kaycie

Meaning & origin

Kaycie is a modern respelling of Casey that first appeared on U.S. naming records in 1965. The name peaked in popularity in the year 2000, but has been steadily declining since then, reflecting a broader shift away from -ie and -y endings that were fashionable in the late 20th century. In 2025 it ranked 4,352, meaning roughly 1 in 50,227 newborn girls received the name. The trajectory shows a falling trend over the past two decades. Kaycie was most common in the 2000s but never achieved widespread national popularity, as indicated by the absence of any top states. The name remains a gentle variant of the more traditional Casey.

Kaycie is a modern phonetic spelling of Casey, which originated as an Anglicized form of the Irish Gaelic surname Ó Cathasaigh, meaning 'descendant of Cathasach', a personal name derived from 'cathasach' meaning 'vigilant' or 'watchful'. The name Casey has been used as a given name since the 20th century, and its variant Kaycie emerged in the mid-1960s, following the trend of respelling established names with a 'y' or 'ie' ending.
