OutRun 2006: Coast 2 Coast, released as OutRun 2 SP in Japan, is a 2006 racing video game developed by Sumo Digital and published by Sega for home systems. It is the ninth title in the Out Run series, and the final one to have a physical release. The game is an updated version of OutRun 2 and is split into two parts: a conversion of OutRun 2 SP (which itself includes the OutRun 2 levels) and "Coast 2 Coast", which includes single-player races and challenges, and local network and internet multiplayer.

OutRun 2006 was released on the Xbox, PlayStation 2 and PlayStation Portable platforms initially, with a PC release following later; in Japan, OutRun 2 SP has only seen a PlayStation 2 release. Each version is subtly different so as to play to the strengths of its home system, which includes a link-up feature between the PS2 and PSP versions, a different mission set for the PSP, and Xbox Live support on the Xbox.
