Buick Century is the model name that was used by Buick for a line of upscale full-size cars from 1936 to 1942 and 1954 to 1958, as well as from 1973 to 2005 for mid-size cars. The first Buick Century debuted as the Series 60 then renamed in 1936 as a shorter and lighter model featuring the same engine as the bigger Roadmaster and Limited series giving it more performance while using the shorter wheelbase body of the Buick Special. During the 1930s and 1940s it was Buick's companion to the top level Roadmaster and was offered as a 2-door and 4-door sedan and convertible. The Century name was used on six generations of cars of varying sizes as well as performance and trim levels. In 1969, Buick developed a concept car known as the Century Cruiser. In the 1970s, the Century Regal became a separate model and market positioning between the two products changed from year to year depending on sales. The Century was updated to front wheel drive in 1982 and was Buick's 2-door coupe, 4-door sedan and station wagon, with regular updates and feature upgrades as customer preferences changed over time.

In 1930, GM built 38,180 cars. The bodystyles available were torpedo, sedan, coupe, and roadster convertible, using GM's "B-body" platform. Starting with this generation, all GM cars shared a corporate appearance as a result of the "Art and Colour Section" headed by Harley J. Earl and modest yearly changes were introduced to freshen the appearance. In 1931, the running board was reduced and the OHV Buick Straight-8 engine was introduced that developed . Aesthetically, the Series 60 remained almost unchanged, and the same fact occurred also in the following year. In 1931 and 1932, a total of 55,135 were produced. In 1933, the length of the body increased and the radiator was now concealed behind a façade with a grille. The engine power increased to , and 1933 was the first year all GM vehicles were installed with optional vent windows which were initially called “No Draft Individually Controlled Ventilation” later renamed "Ventiplanes".
