Action 52 is an unlicensed multicart video game compilation developed by Active Enterprises for the Nintendo Entertainment System and by FarSight Technologies for the Sega Genesis. The NES version was released in 1991, followed by the Genesis version in 1993. The multicart consists of 52 games in a variety of genres, mostly scrolling shooters and platformers. The "featured" game is The Cheetahmen, which was part of Active's failed attempt to create a franchise similar to the Teenage Mutant Ninja Turtles. Active Enterprises was legally incorporated in The Bahamas, but the offices and development were located in Miami, Florida while the company's product warehousing was located in Orlando, Florida.

In video game parlance, a multicart is a cartridge that contains more than one game. Typically, the separate games are available individually for purchase or were previously available individually. For this reason, collections, anthologies, and compilations are considered multicarts. The desirability of the multicart to consumers is that it provides better value, greater convenience, and more portability than the separate games would provide. The advantage to developers is that it allows two or more smaller games to be sold together for the price of one larger game, and provides an opportunity to repackage and sell older games one more time, often with little or no changes.
