Keo

Meaning & origin

Keo is a rare name in the United States, with a unique sound that may draw from different cultural roots. First recorded in 1978, it remained very uncommon for decades but has been steadily rising in use since 1999. In 2025, it ranked 5,861 with an incidence of 1 in 113,872 newborns. Its peak year so far was 2023, indicating a modest but growing appeal. The name has not been associated with any top states in the data, suggesting it is used sporadically across the country. Its multiple possible origins, from Khmer to African, give it a multicultural feel, though its exact meaning remains uncertain. Parents drawn to short, vowel-ending names like Kai or Leo may find Keo an distinctive alternative.

Keo has multiple possible origins. In Khmer (Cambodian), it may derive from the word for 'diamond' (keo). In some African contexts, it can mean 'earth' or 'son of earth'. It is also used as a short form or variant of names like Keanu or Keon in modern English-speaking countries. Its use in the United States dates back to the late 20th century.
