Meaning & origin

Callisto is a name of Greek origin from the word 'kallistos' meaning 'most beautiful.' In mythology, Callisto was a nymph transformed into a bear and later immortalized as the constellation Ursa Major. The name first appeared in U.S. records in 1998 and has remained quite rare, with no rank in the top 1000. Its peak year so far was 2022, but even then it did not reach enough births to register on official charts. The name has shown a stable trajectory into the 2020s, with occasional usage likely inspired by astronomical and mythological themes. Callisto is also the name of a moon of Jupiter, discovered in 1610. Despite its low frequency, the name appeals to parents looking for a distinctive mythological choice with a lyrical sound. No top states have recorded significant usage, suggesting its appeal is scattered rather than regional.

Callisto derives from the Greek word kallistos, meaning 'most beautiful.' In Greek mythology, Callisto was a nymph associated with Artemis who was transformed into a bear and later placed among the stars as the constellation Ursa Major. The name was used sparingly in antiquity and saw modern revival as a mythological and astronomical reference.
