Comet is the name of two fictional comic book characters owned by DC Comics whose adventures have been published by that same company. The first character was a sapient horse with magical powers who was once a centaur in ancient Greece. The second character is a shapeshifter with three forms (male, female, and winged centaur). Both characters are connected to the Superman family of titles.

Comet first appeared in the story "The Legion of Super-Traitors!", published in Adventure Comics #293 (February 1962) during the period known as the Silver Age of Comics. This story introduced the Legion of Super-Pets, bringing together several previously established super animals. Krypto the Super-Dog came from Superman's past, Streaky the Supercat and Beppo the Super-Monkey from Superman's present—and Comet was presented as a super-pet who came from the future. "Yes, readers!" a caption declared, "This is a PREVIEW GLIMPSE of a super-pet Supergirl will own some day in the future!"^[1] The horse was properly introduced seven months later, when Comet met Supergirl in Action Comics #293 (September 1962).^[1]

Due to the events depicted in the 1985 limited series Crisis on Infinite Earths, the first character's stories were no longer considered to be canon within DC's main shared universe, known as the DC Universe, for almost 40 years. However, Comet returned to continuity in the limited series Supergirl: Woman of Tomorrow (published 2021–2022), where he sacrificed his life in the 8th issue to save Supergirl.
