Captain Universe is a fictional character, a superhero appearing in American comic books published by Marvel Comics. It is the guardian and protector of Eternity. Rather than a character with a single identity, Captain Universe is a persona that has merged with several hosts during its publication history.

Captain Universe first appeared in Micronauts #8 and was created by Bill Mantlo and Michael Golden.

Captain Universe hosts have appeared in either special one-shots or short stories throughout the years, initially in the first series of the Micronauts in 1979.

Captain Universe was the starring feature in issues #9-11 of the tryout series Marvel Spotlight. Marvel Spotlight editor Al Milgrom recalled being taken away by the concept of a Captain Universe serial: "You could come up with three issues, three disparate individuals - each one very different from the other - and see how they use their powers. They wouldn't necessarily be superheroic types; they'd be regular people who fell into the powers for just one issue. ... But Captain Universe never got his own title, so I'm guessing it didn't sell terribly well." The character appeared sporadically through the remainder of the 1980s in titles such as Marvel Fanfare and Contest of Champions.

Their appearances became even scarcer in the 1990s, appearing in Guardians of the Galaxy, What If?, The Amazing Spider-Man, Marvel Comics Presents and Cosmic Powers Unlimited.

In 1994 Captain Universe appeared in a one-shot, coinciding with a promotion, with the claim that readers could have a comic about themselves made for a fee. The comics were generally stock stories, with minor details (such as skin or hair color, key names or phrases, etc.) altered based on information provided by the purchaser. Veterinary student Jeff Christiansen, who would later become the force behind the resurgence of the Official Handbooks of the Marvel Universe in the mid-2000s was made the official Captain Universe of the comic so that it could be considered an in-continuity comic. The one-shot was titled X-Men/Captain Universe: Sleeping Giants.
