Rambler is an automobile brand name that was first used by the Thomas B. Jeffery Company between 1900 and 1914.

Charles W. Nash bought Jeffery in 1916, and the name was reintroduced to the automobile marketplace by Nash Motors from 1950 to 1954. The "Rambler" trademark registration for use on automobiles and parts was issued on 9 March 1954 for Nash-Kelvinator.

Nash merged with the Hudson Motor Car Company to form American Motors Corporation (AMC) and the Rambler line of cars continued through the 1969 model year in the United States and 1983 in international markets.

Rambler cars were often nicknamed the "Kenosha Cadillac" after the original location and the largest place of manufacture in the city of Kenosha, Wisconsin.
