Out Run[a] (also stylized as OutRun) is a racing video game released in arcades by Sega in September 1986. It is known for its pioneering hardware and graphics, nonlinear gameplay, and a selectable soundtrack with music composed by Hiroshi Kawaguchi. The goal is to avoid traffic and reach one of five destinations.

The game was designed by Yu Suzuki, who traveled to Europe to gain inspiration for the game's stages. Suzuki had a small team and only ten months to program the game, leaving him to do most of the work himself. The game was a critical and commercial success, becoming one of the best-selling video games of its time and Sega's most successful arcade cabinet of the 1980s. It was ported to numerous video game consoles and home computers and spawned a number of sequels. Out Run has been cited as an influence upon later video games.
