Oldsmobile was a brand of American automobiles produced for most of its existence by General Motors. Originally established as "Olds Motor Vehicle Company" by Ransom E. Olds in 1897, it produced over 35 million vehicles, including at least 14 million built at its Lansing, Michigan factory alone. During its time as a division of General Motors, Oldsmobile slotted into the middle of GM's five divisions (above Chevrolet and Pontiac, but below Buick and Cadillac), and was noted for its groundbreaking technology and designs.

Over 1 million Oldsmobiles were sold annually in 1983, 1984, 1985 and 1986 but by the 1990s, the division was facing growing competition from premium import brands and sales declined. When shut down in 2004, Oldsmobile was the oldest surviving American automobile marque, and one of the oldest in the world, after Mercedes-BenzPeugeotSkodaTatra, and Vauxhall.
