The Renault 8 is a rear-engined, rear-wheel drive small family car produced by the French manufacturer Renault in the 1960s and early 1970s. It also formed the basis for the larger Renault 10, introduced in 1965.

In automobile design, a rear-engine design layout places the engine at the rear of the vehicle. The center of gravity of the engine itself is behind the rear axle. This is not to be confused with the center of gravity of the whole vehicle, as an imbalance of such proportions would make it impossible to keep the front wheels on the ground.
