Amos Earl Northup (October 23, 1889 – February 8, 1937) was an American automotive designer.
Regarded as a leader in the field in the United States by the late 1920s, Northup worked for the Wills Sainte Claire, Murray Corporation of America, Hupmobile, American Austin, REO, Willys-Overland, Willys-Knight, and Graham-Paige automakers during his career.
[citation needed] Northup was employed by cabinet maker C. J. Wadsworth in Painesville, Ohio, early in his career.
By the time Northup was appointed Art Director and Chief Designer for Willys-Overland in March 1928 he was considered a leading automotive stylist of the day.
[citation needed] He designed the 1929 Willys Whippet lines and 1929 Willys-Knights and the 1932 Graham Bluestreak which was viewed as a revolution in automotive design with more enclosed fenders and a backward sloping grill and radiator cap moved to under the hood.
