Born in Georgia, he graduated from the Academy of Richmond County, then from Emory University in 1932. Potter entered graduate school at Yale the same year, but he left four years later without finishing his dissertation. He taught at the University of Mississippi for two years, then taught at Rice University for another two before completing his dissertation in 1940 under Ulrich Bonnell Phillips.In 1942 Yale published his dissertation as Lincoln and His Party in the Secession Crisis and hired him as an assistant professor. As professor of history at Yale University in 1942–1961 and Coe Professor of American History at Stanford University in 1961–1971 he directed numerous dissertations and served on numerous editorial and professional boards. He also held the Walgreen Lectureship at the University of Chicago, and the Commonwealth Fund Lectureship at the University of London. Potter held the Harold Vyvyan Harmsworth Professor of American History at Oxford University in 1947. He was a pioneer in sponsoring the study of Women's history.
Potter posthumously won the 1977 Pulitzer Prize for History for The Impending Crisis, 1848-1861 (1976), an in-depth narrative and analysis of the causes of the American Civil War.

He considered himself a conservative and was a prominent exponent of Consensus history.
