Micro Machines is a racing video game developed by Codemasters and originally published by Camerica for the Nintendo Entertainment System (NES) in 1991. Themed around Galoob's Micro Machines toys, players race in miniaturised toy vehicles around various environments. The game is the first instalment in the Micro Machines video game series.

Micro Machines was developed because Galoob wanted Codemasters to develop a game based on their toy brand, although Galoob and Codemasters encountered legal issues with Nintendo over the game being unlicensed. Micro Machines was ported to several systems, and received remakes for the Xbox, PlayStation 2, and GameCube in 2002. Micro Machines's reception was positive, with reviewers praising the originality and two-player mode, although some criticised the sprites on some versions. A sequel, Micro Machines 2: Turbo Tournament, was released in 1994, and the series was revived in 2016 with the release of a title for iOS and Android.
