The H platform, or H-body, name has been used twice by General Motors. It was part of the successor to the mid-size G-body, which was used by the pre-1986 Pontiac Bonneville. The 1970s H-body was an inexpensive rear-wheel drive subcompact automobile platform from the 1970s. The 1980s H-body was a front-wheel drive full-size car platform.

The 1980s H-bodies were full-size front-wheel drive cars with a 110.8 inch wheelbase. Most H-bodies used GM's large 3800 V6, and supercharged versions were introduced in 1991. They came in both 2-door and 4-door versions, but the four door sedans were dramatically more popular.

According to one source(1), the H-Body sedans were the next "big thing" for GM, and development cost more than $3 billion, which is on par with roughly how much Ford invested in the Ford Taurus. Both the H-body sedans and the Taurus (based on the D186 platform) were launched fully in 1986.

In the 2000s the H-body chassis is currently used by the Buick Lucerne and also was used for the Pontiac Bonneville. The chassis identification can be found on the 4th letter of the VIN.
