The 1940 United States Senate election in Missouri was held on November 5, 1940. Incumbent Democratic U.S. Senator and future President of the United States Harry S. Truman, who was first elected in 1934, decided to seek re-election to a second term. He narrowly survived a primary challenge from Governor of Missouri Lloyd C. Stark before also narrowly defeating Republican nominee Manvel H. Davis in the general election.
