The Buick Super is a full-sized automobile produced from the 1940 through the 1958 model years (excluding WW II). It was built on Buick's larger body shared with the Roadmaster and was replaced by the Riviera in 1964.

Super returned as a performance trim level on V8-powered LaCrosse and Lucerne sedans from 2008 until 2011.

Originally the Series 50 had a 331.4 cu in (5,431 cc) six cylinder engine developing 99 bhp of power at 2,800 rpm, and Buick manufactured 28,204 cars. In 1931 the model remained almost unchanged, aside from minor appearance changes. Optionally, the model was equipped with a new 220.7 cu in (3,617 cc) straight eight-cylinder and 77 hp. With the temporary disappearance of the Series 40, Series 50 became the entry level model for Buick.

In 1932 the engine displacement increased to 230.4 cu in (3,776 cc), producing 82.5 bhp. In 1933, the aesthetics of the car was completely redesigned. The power delivered by the engine was increased again and now it was up to 86 bhp, and in 1934, the model power increased to 88 hp. Buick re-introduced the Series 40, which once again became the entry level model. In 1935 the Series 50 remained unchanged and the following year went out of production, having produced 127,416 examples. The model was reintroduced in 1940 under the name "Super".

When introduced in 1940 the new Series 50 Super featured the cutting-edge "torpedo" C-body. The new C-body that the 1940 Buick Super shared with the Series 70 Roadmaster, the Cadillac Series 62, the Oldsmobile Series 90, and the Pontiac Torpedo featured shoulder and hip room that was over 5" wider, the elimination of running boards and exterior styling that was streamlined and 2-3" lower. When combined with a column mounted shift lever the cars offered true six passenger comfort, changes that had clearly been influenced by the Cadillac Sixty Special.

The basic formula for the 1940 to 1952 Super was established by mating the Roadmaster's longer behind the engine cowl body to the Series 40 Special's smaller straight-eight engine (and consequently shorter engine compartment). This led to an economical combination of voluminous passenger room and relatively good fuel economy. (In contrast the Series 60 Century combined the smaller Special body with the larger Roadmaster engine.)
