The Buick Riviera was an automobile produced by Buick in the United States from the 1963 to 1999 model years, with 1,127,261 produced. A full-size coupe or personal luxury car, the early models of the Riviera in particular have been highly praised by automotive journalists and writers.

The Riviera name first entered the Buick line in 1949 as the designation for the new two-door pillarless hardtop, which was described in advertising as "stunningly smart." The Roadmaster Riviera(along with the Cadillac Coupe de Ville) constituted the first mass production use of this body style, which was to become extremely popular over the next 30 years

1999 was the last model year for the Riviera, a very short one, with production of 1,956 cars ceasing on November 25, 1998. The final 200 cars had special silver paint and trim, and were denoted "Silver Arrow" models, a designation which hearkened back to several Silver Arrow show cars that had been built off Riviera bodies by Bill Mitchell.
