Cannon Spike (Gunspike in Japan) is an overhead-camera shooting game in the vein of Smash TV and another Capcom creation, the Commando series. Released for the arcades, and later for the Sega Dreamcast, it uses Capcom-designed characters and runs on Sega's Naomi Hardware.

Cannon Spike is a linear game, heavily focused towards boss encounters. A main feature of the game is the ability to play as a number of familiar Capcom characters from other franchises. The international name of Cannon Spike is the name of a trademark attack performed by Cammy, a character from the Street Fighter series of video games and one of the protagonists of this title.
