The 1936 United States Senate election in Kansas took place on November 3, 1936. Incumbent Republican Senator Arthur Capper ran for re-election to a fourth term. He was challenged by former Wichita Mayor Omar Ketchum, the 1934 Democratic nominee for Governor. Even though Kansas Governor Alf Landon was the Republican nominee against President Franklin D. Roosevelt in the 1936 presidential election, Roosevelt won Kansas by a wide margin over Landon, and Capper only narrowly defeated Ketchum.
