The General Motors X platform (also called X-body) is a rear-wheel drive compact car automobile platform produced from the 1962 to 1979 model years. Developed by Chevrolet, the architecture was initially unique in the U.S. to the Chevy II, first joined by the Pontiac Ventura in 1971, then a range of other GM products as its divisions expanded their compact model lines.

For 1980, the platform was discontinued and the X-body designation was reused for its downsized front-wheel drive successor, the first FWD compact car architecture produced by General Motors.
