Ridge Racer Unbounded is a 2012 racing video game developed by Bugbear Entertainment and published by Namco Bandai Games. It was released for Microsoft Windows, PlayStation 3 and Xbox 360. It is the eighth installment of the Ridge Racer franchise following Ridge Racer 7, the first mainline title not to be developed by Namco, and the first in the series overall to be released on Windows. Unbounded is also the most recent game in the series to be released on home consoles as its successors only focused on handheld devices.

Unbounded marks a departure from the traditional Ridge Racer drifting style, and moved to a more combat-oriented and destructive style, similar to the Burnout series and Split/Second, as well as implementing customizations. The game received average reviews.
