Red Steel is a first-person shooter video game published by Ubisoft for Nintendo's Wii console. It was developed by the Ubisoft Paris studio and was unveiled in the May 2006 issue of Game Informer. It was released on November 19, 2006 in North America, the date of the Wii launch.

The game takes advantage of the Wii's motion-sensitive controller, along with the Nunchuk attachment, to control a katana and a firearm. The on-screen gun hand points the gun in the same direction the Wii Remote is pointing. Players can push objects to use them as cover by pushing the controller forward. Shaking the Nunchuk attachment or pressing "right" on the D-Pad reloads the gun. The player can also throw grenades underhand or overhand by moving the Nunchuk as though it were the actual grenade.
