Roadblock was a combat robot that competed on the British television series Robot Wars. Constructed in 1997 by A-level students from Bodmin Community College, the robot was initially called "Road Rage" but was renamed in response to a request from the programme's producers. Both names were derived from the robot's distinctive construction from metal roadsigns. Roadblock was champion of the first series of Robot Wars and finished in third place for the second series. Although Roadblock was armed with a circular saw weapon, its success was primarily due to its wedge-shaped body—Roadblock could drive underneath opponent robots and invert them, rendering many immobile.

Robot combat is a type of robot competition in which custom-built machines fight using various methods to incapacitate each other. The machines have generally been remote-controlled vehicles rather than autonomous robots.
