The General Motors A platform (commonly called A-body) was an automobile platform.

From at least 1936 through 1958, GM used at least four different designations for various bodyshells/platforms including the A-body for Chevrolet, most Pontiacs, and the Oldsmobile Series F and Series 60, the B-body for the Pontiac Streamliner Torpedo and Streamliner, the Oldsmobile Series L, Series 70 and Series 88, the Buick Special and Century, the LaSalle Series 50, and the Cadillac Series 60, Series 61 and Series 63, and the C-body for the Pontiac Series 24/29 Torpedo, Oldsmobile 90, the Buick Roadmaster, Super and 1958 Limited, the LaSalle Series 52, and all remaining Cadillacs except for the Series 90, Series 85 and the Series 75 which were built on the D-body, along with all remaining Buick Limiteds. For the 1959 model year, the previous A and B bodies were built on the new B-body that lasted until 1996. For the 1959 model year, the previous A and B bodies were built on the new B Body[1][2] that lasted until 1996.

The A-body designation would be resurrected by GM in 1964 for a new series of intermediate-sized cars including the Chevrolet Chevelle, Pontiac Tempest, Oldsmobile Cutlass and Buick Skylark. These later A-bodies underwent a switch in drive layout from rear wheel drive to front wheel drive in 1982. The switch in drive layout spawned the G-body. In 1997, every A-body car line was cancelled, but new nameplates on the GM W platform have taken their place.
