Kacey is Irish in Origin.

Kacey is a contemporary respelling of Casey, the Anglicized Irish surname O Cathasaigh that became a given name. It ultimately derives from the Gaelic personal name Cathasach, built on cath "battle" with the adjectival suffix -asach, yielding meanings such as "vigilant," "watchful," or "battle-ready." Used in English as a truly unisex choice, Kacey shares the same roots and sense as its older form.

As a given name, it followed the 19th-20th century fashion of surnames crossing into first-name use, with the Kacey spelling gaining ground in the late 20th century, especially for girls, through figures like country singer Kacey Musgraves. Variants include Casey, Kasey, Kacie, Kacy, Kaci, Kasie, Kayce, and the initial-style KC; the rare Gaelic form is Cathasach. Short forms such as Kay or Case occur. While sometimes associated by sound with Katherine or Cassandra, Kacey's established etymology is Irish, carrying the meaning of alertness and spirited courage.
