Roosevelt was a Vintage era marque of an American automobile that was manufactured by the Marmon Motor Car Company of Indianapolis, Indiana, during the 1929 and 1930 model years.^[1]

The Roosevelt was named after President Theodore Roosevelt and designed to be priced as an "affordable" automobile, and advertising used the tag line Smart Transportation for the Thrifty.^[2] The Roosevelt was the first automobile in America with a straight-eight engine to be priced under $1,000, with the sedan and coupe selling for $995, equivalent to $17,655 in 2023.^[3]

Although the Roosevelt name did not appear for the 1931 range of Marmon models, the car was refined into the new Model 70 Marmon.^[1]

Sales in 1929 approached 24,500 automobiles, considered an excellent first year for a new marque. One of the unique features of the Roosevelt was the horn button. It served 3 purposes. Push down and it would honk, pull up and it was the starter, and turn it, to turn the head lights on and off. It also had a cameo of Theodore Roosevelt, black and white, on the front top middle of the radiator.^[4][1]
