OutRun 2 (アウトラン2) is a 2003 racing game developed by Sega AM2 for arcades. It was the first entry in Sega's OutRun series in a decade, following OutRunners (1993), and marked the fourth arcade installment. As with previous titles in the series, gameplay revolves around driving a Ferrari sports car and participating in various races and challenges.

OutRun 2 was originally released for the Sega Chihiro arcade hardware, and was ported to the Xbox home console in 2004. The game received generally favorable reviews. Updated versions subtitled SP and SP/DX were later released. It was followed by a sequel, OutRun 2006: Coast 2 Coast, which retained most of its predecessor's content alongside new features.

OutRun 2 stays true to the race format from the 1986 original, in which the player is behind the steering wheel of a Ferrari sports car with a friend in the passenger seat through 5 of 15 stages. As before, the player can choose their course and the soundtrack. OutRun 2 has been overhauled with 3D graphics and a local networked multiplayer system.

Sega licensed seven Ferrari vehicles for OutRun 2, including the Testarossa from the original game.

The soundtrack was completely rearranged, bringing in seven pieces of music with styles ranging from instrumental rock to upbeat ballads. The original 1986 music is also unlockable.

OutRun 2 provides three single-player game modes: "OutRun mode", "Heart Attack mode" and "Time Attack mode":

All unlockable bonus secret tracks are from Scud Race and Daytona USA 2 on the Xbox version.

Developing the game precipitated some changes for its developers, Sega AM2, who had historically written their games using Unix systems. Writing for an Xbox-based system meant they had to adapt to the Microsoft Windows kernel.^{[citation needed]}
