The General Motors K platform (commonly called the K-body) was the basis of the Cadillac Seville model over two entirely different automobile platforms.

The front-wheel drive K-body was used for full-size Cadillacs from 1980 onwards. K-bodies were sedans; coupés used the nearly identical GM E platform. The 1986– K- and E-bodies were produced at GM's high-tech Detroit/Hamtramck Assembly plant.

Unlike most GM platforms, the K was not shared by multiple divisions (though the E was). Technically, though, the architecture was shared under a different name: the GM G platform was based on the K and produced at the same time.

The K platform was updated in 1997 with improved suspension geometry. The Seville was replaced with the rear-wheel drive Sigma-based Cadillac STS for 2005, but the Deville's replacement, the DTS continues on the K-body.
