Mego Corporation is a toy company that was originally 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 dolls (including the long-running "World's Greatest Super Heroes" line), celebrity dolls, and the Micronauts toy line. For a time in the 1970s, their line of 8-inch-scale dolls with interchangeable bodies became the industry standard.

In 1982 Mego filed for bankruptcy, and by 1983, the Mego Corporation ceased to exist today, Mego dolls and playsets can be highly prized collectibles, with some fetching hundreds, or even in some cases, thousands of dollars (depending on rarity) in the collectibles market. In July 2018, the newly-reformed Mego Corporation announced they would be producing a run of their classic style clothed dolls in their traditional 1/9 scale, as well as some 1/5 figures.
