The name Chevrolet Greenbrier was used by Chevrolet for two vehicles. The first vehicles were a six-to-nine-passenger window van version of the Corvair 95 van. The Corvair 95 series also included the Loadside pickup truck and Rampside pickup truck that featured a mid-body ramp on the right side. All used the Corvair powertrain in a truck body and were produced in the model years 1961 to 1965.

The Chevrolet Corvair is a rear-engined, air-cooled compact car manufactured by Chevrolet in two generations between 1960–1969. A response to the Volkswagen Beetle, it was produced in 4-door sedan, 2-door coupe, convertible, 4-door station wagon, passenger van, commercial van, and pickup truck body styles in its first generation (1960–1964), and as a 2-door coupe, convertible or 4-door hardtop in its second (1965–1969). Total production was approximately 1.8 million vehicles from 1960 until 1969.
