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 is a top-down racing game: players observe races from above. Players race in environments such as breakfast and pool tables, work desks, and treehouses, driving toy vehicles such as powerboats, helicopters, formula one cars, and tanks that can shoot other racers. Courses have a predefined path that racers must follow: if a player leaves the defined route for too long they are sent back to the track. Many have obstacles such as cereal boxes on breakfast tables, and pencil sharpeners on desks.
