Cozmo is an unusual and distinctive given name of American origin. It is believed to have been invented by science fiction author Jack Vance for his series "The Dying Earth," where it appeared as a character's name in the story "Cumpsty Cozmo." The name gained some popularity in the United States during the latter half of the 20th century, likely due to its association with Vance's works. Today, while still relatively rare, Cozmo can be found among baby names, standing out for its unique sound and literary roots.
"Cozmo, while unique and distinctive, hasn't gained much traction yet with just 5 births recorded since 2008."
