Meaning & origin

Sagan is a modern unisex name that first appeared in U.S. records in 1987. It reached its peak popularity in 2018, but has been falling in use since 2017. As of 2025, it ranks 5,399th, with about 1 in 100,475 newborns given the name. The name is most commonly used in Texas. Sagan's appeal likely stems from its celestial sound and association with astronomer Carl Sagan, though the name itself is a modern invention without deep historical roots.

Sagan is a modern invented name with no clear linguistic derivation. It may be a surname transferred to first name use, or a respelling of names like Seagan or Saegan. The name gained minor popularity in the United States from the late 20th century onward.
