The Buick Roadmaster is an automobile built by Buick from 1936 until 1942, from 1946 until 1958, and then again from 1991 until 1996. Roadmasters produced between 1936 and 1958 were built on Buick's longest non-limousine wheelbase and shared their basic structure with the entry-level Cadillac Series 65, the Buick Limited, and after 1940, the Oldsmobile 98. Between 1946 and 1957, the Roadmaster served as Buick's flagship.
After being resurrected in 1991, the Roadmaster became the marque's largest vehicle, measuring 10 in (254 mm) longer with a 5 in (127 mm) greater wheelbase than the C-body Buick Park Avenue. This generation was the first in Roadmaster history to be built on the General Motors B-body platform rather than the C-body, which had traditionally been reserved for GM's largest and most opulent models that were not Cadillacs.
A Buick Roadmaster Estate station wagon was introduced in 1947 and was manufactured in several generations through 1996. The final run of 1991-1996 Roadmasters shared powertrains and platforms with the Chevrolet Caprice, Cadillac Fleetwood, and Oldsmobile Custom Cruiser.
