The Packard Twelfth Series One-Twenty is an automobile produced by the Packard Motor Car Company of Detroit, Michigan, from 1935 to 1937 and from 1939 through the 1941 model years. The One-Twenty model designation was derived from the wheelbase, and it was replaced by the Packard 200.
The One-Twenty signified the first time that Packard had entered into the highly competitive mid-priced eight-cylinder car market. Packard enthusiasts view the production of the One-Twenty and the Six/One-Ten models as the start of Packard's losing its hold on the market as the premier American luxury automotive brand. It was a marketing strategy shared with GM's LaSalle, the Chrysler Airstream, and the Lincoln-Zephyr. It was introduced after Rolls-Royce brought to market the Rolls-Royce Twenty, which was manufactured between 1922 and 1929 (succeeded by the Rolls-Royce 20/25 which was built until 1936).
The introduction of the One-Twenty (and later the Six/One-Ten models) was a necessary move to keep Packard in business during the final years of the Great Depression, expanding on an earlier approach with the Packard Light Eight
