The Buick Reatta was the first car Buick advertised as a two-seater since the 1940 Buick model 46. It was a hand-made luxurious sports coupe produced at the Lansing Craft Centre in Lansing, Michigan and sold by the Buick division of American automaker General Motors from early 1988 to 1991. Like the Cadillac Allante, it was based on a shortened version of the GM E platform used by the Cadillac Eldorado, Oldsmobile Toronado and particularly the Buick Riviera, with which it shared its advanced electronics and interior furnishings.

The Reatta was intended as a halo car for Buick, but sales, originally planned to be around 20,000 units a year, were extremely disappointing and GM announced the end of Reatta production in early 1991. Production is said to have begun in January 1988 and ended on May 14, 1991. However, various accounts of much earlier and later cars exist, and the handbuilt nature of the car and long development cycle makes accurately dating production difficult.
