Micronauts was a North American science fiction toyline manufactured and marketed by Mego from 1976 to 1980. The Micronauts toyline was based on and licensed from the Microman toyline created by Japanese-based toy company Takara in 1974.

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.
