Meaning & origin

Kleo is a modern, streamlined name that first entered U.S. records in 2005. Its trajectory has been steadily rising since 2009, reaching its peak rank of 2,859 in 2025. This rarity is underscored by its one-in-27,242 frequency that year, making it an uncommon choice. The name's top states are Texas and California, reflecting broader trends for inventive, vowel-suffixed names. As a recent coinage, Kleo lacks deep historical roots, but its similarity to Cleo and the Greek concept of 'glory' lends it a spunky, melodic appeal.

Kleo is a modern name that emerged in the United States in the early 2000s. It may derive from Cleopatra, the famous Egyptian queen, via the nickname Cleo, or it could be a direct coinage from the Greek word 'kleos' (glory), as seen in names like Cleopatra. The spelling with a K gives it a contemporary feel, distinguishing it from the more traditional Cleo.
