Kesey is a modern unisex given name in English-speaking countries, most often arising as a surname-turned-first name and boosted in visibility by the American novelist Ken Kesey. It appears sporadically in U.S. records from the late 20th century onward and remains rare, fitting contemporary tastes for crisp two-syllable, -sey/-see endings. Parents sometimes choose it as a literary homage or as a fresh alternative to familiar favorites.

Linguistically, Kesey is commonly treated as a phonetic cousin to two sources. If aligned with Irish Casey (from Ó Cathasaigh), it carries the meaning “vigilant” or “watchful.” If viewed as a reshaped form of English Kelsey, it echoes that name’s Old English roots - either a place-name sense “Ceol’s island” (Ceol + ēg) or the personal name Ceolsige, “ship’s victory.” Variants and related forms include Keesey, Keasey, Kesy, Kasey, Casey, Kelsey, and Kelsie; short forms include Kes or Kess.
