The Micronauts are comic books featuring a group of characters based on the Mego Micronauts toy line. The first title was published by American company Marvel Comics in 1979, with both original characters and characters based on the toys. Marvel published two Micronauts series, mostly written by Bill Mantlo, until 1986, well after the toy line was cancelled in 1980. In the 2000s, Image Comics and Devil's Due Publishing each briefly published their own Micronauts series. Byron Preiss Visual Publications also published three paperback novels based on the Micronauts. In 2016, IDW Publishing published a new comic book series. A live-action film version of the Micronauts was in development by Hasbro Studios and Paramount in 2015. In May 2023, Marvel re-acquired the licensing rights to publish The Micronauts.

The Mego Corporation is an American toy company that in its original iteration was first founded in 1954. Originally known as a purveyor of dime store toys, in 1971 the company shifted direction and became famous for producing licensed action figures, celebrity dolls, and the Micronauts toy line. For a time in the 1970s, their line of 8-inch-scale action figures with interchangeable bodies became the industry standard.
