Micro Machines is a series of video games featuring toy cars, developed by Codemasters and published on multiple platforms (MS-DOS, Nintendo Entertainment System, Amiga, Sega Mega Drive/Genesis, Super Nintendo Entertainment System, Game Boy, PlayStation 2, Nintendo 64, GameCube, Xbox, Game Gear, and iOS). The series is based on the Micro Machines toy line of miniature vehicles.

Micro Machines games feature tracks based on household settings: for example, kitchen tables and desktops. The tracks also contain obstacles in the form of household items; often the possibility of falling off the track is a hazard in itself.

Micro Machines, the first game in the series, laid the foundation of the gameplay: a top-down racing game with miniature vehicles. The race tracks are unconventionally themed. For example, some races take place on a billiard table while others occur in a garden. The cartridge itself was sold in several versions. There was a gold (black in PAL regions) cartridge with a switch at the bottom in order to be compatible with the American and European hardware. In Europe there was also a version where the cartridge was in the form of a plug through cartridge, a cartridge you plugged on another, normal NES cartridge and then inserted it in the machine. It was also released as an add-on to the Aladdin Deck Enhancer created by Codemasters.

A remake of this game was later released in 2002. This version features advanced graphics as well as drivers having unique vehicles.

A free-to-play port for iOS devices was released on 14 July 2016, and Android devices and Remix OS computers later in November. Published by EA subsidiary Chillingo and developed by Codemasters, the game, based extensively on PC, PS3 and Xbox 360 racing game Toybox Turbos, allows players to compete against one another across the internet, local WiFi or Bluetooth in races and vehicular battles. Although free to play, the game features in-app purchases allowing players to speed up progress by purchasing coins and gems, which in turn are used to buy additional parts for a variety of cars, ranging from transportation such as buses and taxis to rally cars, military vehicles and construction equipment. Players can also join a club of other racers and compete with other clubs for weekly rewards.

Plagued with server and coding issues, Chillingo retired the game and closed the servers in August 2018.

Micro Machines 2: Turbo Tournament was released in 1994 and featured vehicles which required different handling techniques for each course, including hovercraft and helicopters. There are different playing modes including "head-to-head", in which each player earns points by driving a full screen ahead of the opponent. TV presenter Violet Berlin features as a playable driver. The MS-DOS version featured a track editor which allowed players to create their own custom vehicles, backgrounds and obstacles and export and import tracks.

A selling point for the Sega Genesis/Mega Drive version was the J-Cart, a cartridge including two control ports, thus eliminating the need for a 4-player adaptor. It also included a 'pad-sharing' feature that allowed 2 players to share a single joypad; thus it enabled 8 players to compete simultaneously on certain tracks.
