The 1940 United States presidential election in South Carolina took place on November 5, 1940. All contemporary 48 states were part of the 1940 United States presidential election. State voters chose eight electors to the Electoral College, which selected the president and vice president.

South Carolina was won by incumbent Democratic President Franklin D. Roosevelt of New York, who was running against Republican businessman Wendell Willkie of New York. Roosevelt ran with Henry A.
