Traci Thirteen aka Girl 13 and Traci 13 is a fictional character published by DC Comics. She first appeared in Superman #189 (February 2003), and was created by Joe Kelly and Dwayne Turner.

The latest in the long line of "Homo Magi," humans born with innate powers of sorcery, Traci is forbidden by her father, Doctor Thirteen, to practice magic, since her mother died due to magical influences.

Traci moved to the Suicide Slum of Metropolis, determined to live on her own (with her pet iguana Leeroy). There she began to tap into the "urban magic" of Metropolis, and assumed the name of Girl 13, becoming a super hero of sorts. She met Superboy, who was attracted to her, but the feeling was not mutual. She used her magic to defend an injured Superman from a ghostly female ninja, along with fellow "Supergirls," Natasha Irons and Cir-El, with whom she formed a friendship. The Spectre's attack on magic during the Day of Vengeance mini-series does not seem to have had an effect on her powers.

In the one-shot Day of Vengeance: Infinite Crisis Special Traci joined a large group of mystical heroes, including Doctor Occult, the Phantom Stranger, and Rex the Wonder Dog in cleaning up one of the Spectre's many rampages. The Rock of Eternity had exploded over Gotham City, unleashing multiple mystical horrors. The group soon recreated the rock, trapping the demons again.

Traci 13 has not been a contender in any CBUB matches.
