Kaysey is Irish in Origin.

Kaysey is a modern, phonetic spelling of Casey/Kasey, a unisex given name derived from the Irish surname Ó Cathasaigh. The surname comes from the personal name Cathasach, meaning “vigilant, watchful,” and is related to cath, “battle,” which also yields the folk sense “brave in battle.” Casey migrated from surname to first name in the English-speaking world, buoyed by cultural touchstones such as the 1888 poem “Casey at the Bat” and figures like railroadman Casey Jones; use for girls rose sharply in the U.S. and elsewhere from the 1970s onward.

Kaysey preserves the same sound while offering a softer, contemporary look. It remains rarer than Casey, Kasey, or Kacey, but fits with creative Y/ey spellings. Common variants include Casey, Kasey, Kacey, Kacie, Kaci, Kaycie, Kaycee, Kayce, and the initialism KC. The name is comfortably unisex, with meanings typically given as “watchful,” “vigilant,” or “brave.”
