Meaning & origin
Kassey entered U.S. naming records in 1978 and peaked in 1992, the year it reached its highest usage among newborn girls. Though never common, the name has maintained a stable trajectory, with its 2025 rank of 13,208 reflecting a consistent but low level of use. The 1-in-267,878 ratio indicates that fewer than 30 newborn girls were named Kassey that year. As a modern invention or an Anglicized variant of Casey, it fits a pattern of late 20th-century American names that substitute 'K' for 'C' and add playful suffixes. Its top states are not recorded, suggesting it has never concentrated in any region.
Kassey first appeared in the United States in 1978. It is likely an invented spelling variant of Casey, which itself derives from an Irish surname, or a modern coinage influenced by the fashionable sound of names like Kassidy. The spelling with a 'K' and 'ey' ending reflects late 20th-century American naming trends favoring unique phonetic spellings.
