The Cadillac DTS (DeVille Touring Sedan) is a full-size luxury sedan produced by General Motors, an American automobile company. The DTS replaced the Cadillac DeVille as General Motors' largest luxury car for the 2006 model year. This renaming followed new styling conventions set by the earlier CTS and STS.

The first version of the DTS was initially shown at the 2005 Chicago Auto Show on February 9.
