Coleman Livingston Blease (October 8, 1868 – January 19, 1942) was an American politician of the Democratic Party who served as the 89th governor of South Carolina from 1911 to 1915, and as a United States senator from 1925 to 1931. Blease was the political heir of Benjamin Tillman. He led a political revolution in South Carolina by building a political base of white textile mill workers from the state's upcountry region. He was notorious for playing on the prejudices of poor whites to gain their votes and was an unrepentant white supremacist. Ultimately, despite his political strength, Blease failed to pass any significant legislation while governor.

Blease was notorious for his vituperative demeanor. He did not campaign on political promises but on the prejudices of white citizens. Blease advocated lynching and was against education for black people. As U.S. senator, he advocated penalties for interracial couples attempting to get married, criticized US First Lady Lou Hoover for inviting a black guest to tea at the White House, and was the architect of Section 1325.
