Thaddeus Bodog Sivana is a supervillain appearing in American comic books published by DC Comics. Doctor Sivana is the archnemesis of Captain Marvel created by Bill Parker and C. C. Beck, first appearing in Whiz Comics #2 (cover-dated February 1940) by Fawcett Comics. A mad scientist and inventor bent on world domination, the character was established as Captain Marvel's main archenemy during the Golden Age, appearing in over half of the Fawcett Captain Marvel stories published between 1939 and 1953. Sivana has kept his role as one of the key archenemies of Captain Marvel (now Shazam) throughout the character's appearances in DC Comics, which eventually acquired the rights to Fawcett's superhero characters. In 2009, Doctor Sivana was ranked as IGN's 82nd-greatest comic book villain of all time.

Doctor Sivana has made his cinematic debut in the DC Extended Universe 2019 film Shazam!, portrayed by Mark Strong, who reprised the role in a post-credits scene cameo in the 2023 sequel Shazam! Fury of the Gods.
