Kasey, a modern variant of the Irish surname Casey, entered the U.S. naming landscape in 1950. It reached its peak popularity in 1987, ranking high among female names, and has since followed a downward trajectory, declining steadily since 1988. As of 2025, the name ranks 1,872 nationally, with about 1 in 15,307 newborns receiving it. Kasey has been most prevalent in Kentucky, Virginia, and Georgia, reflecting its Southern and Appalachian appeal. The name's phonetic simplicity and gender-neutral quality have kept it in steady, if reduced, use across the decades.

Kasey is a spelling variant of Casey, which comes from the Irish surname Ó Cathasaigh, meaning 'descendant of Cathasach.' Cathasach is a personal name derived from 'cathas,' meaning 'vigilant' or 'watchful.' The name has been used as a given name for both boys and girls, with its popularity rising in the United States during the mid-20th century, particularly for girls.
