Meaning & origin
Caelum entered the U.S. baby name charts in 1995, a relatively recent addition to the roster of celestial-inspired names. Its Latin origin ties it to a tradition of astronomical and mythological names, yet it remains uncommon. In 2025, it ranked 1,688, with a 1-in-17,609 incidence rate. Its popularity has been rising steadily since 1997, and it reached its peak rank in 2025. The name has shown particular favor in Virginia, New York, and California. While still rare, Caelum fits a modern trend of concise, classical names with bright, airy associations.
Caelum is the Latin word for 'sky' or 'heaven'. It was revived in the 1990s as a given name, likely influenced by the constellation Caelum (the Engraver's Tool) and the popularity of other Latin astronomical names. Its usage remains rare in English-speaking countries.
