The Dodge St. Regis is an automobile that was marketed by Dodge from the 1979 to 1981 model years. Replacing the Monaco, the St. Regis was the largest Dodge sedan, slotted above the mid-size Diplomat and Aspen. In contrast to both the Monaco and the Diplomat, the St. Regis was offered solely as a four-door sedan. Produced for a single generation, the St. Regis is one of the shortest-lived Dodge nameplates.
