Casey originates from the Irish surname Cais or Ó Cathasaigh, which stems from the Gaelic word *cathasach* meaning “vigilant” or “watchful.” The name was historically a clan name in County Kerry and surrounding regions of Ireland. During the 19th century, large numbers of Irish immigrants brought the surname to the United States, where it gradually shifted from a family name to a given name.

In America, Casey first appeared as a male first name in the early 20th century, gaining popularity during the mid-1900s. Its use broadened as parents sought short, easy-to-spell names with a friendly sound. Variants such as Kasey, Kacey, and Case appear, with Kasey often favored for girls, though the name remains largely unisex today. The name’s Irish roots are well documented, and its meaning of vigilance has remained consistent across spellings.

American cultural exposure—through athletes, actors, and fictional characters named Casey—has reinforced its familiarity. While the name retains its Irish heritage, it is now firmly part of the broader U.S. naming landscape, appreciated for its crisp pronunciation and positive connotation of alertness.
