Out Run (also stylized as OutRun) is an arcade driving video game released by Sega in September 1986. It is known for its pioneering hardware and graphics, nonlinear gameplay, a selectable soundtrack with music composed by Hiroshi Kawaguchi, and the hydraulic motion simulator deluxe arcade cabinet. 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 the highest-grossing arcade game of 1987 worldwide as well as Sega's most successful arcade cabinet of the 1980s. It was ported to numerous video game consoles and home computers, becoming one of the best-selling video games at the time and selling millions of copies worldwide, and it spawned a number of sequels. Out Run is considered one of the most influential racing games, cited as an influence upon numerous later video games, playing a role in the arcade video game industry's recovery, and providing the name for a popular music genre.
