U.S. Senate election, 1930

The U.S. Senate election, 1930 was an election for the United States Senate which occurred in the middle of Republican President Herbert Hoover's first term. With the Great Depression beginning to take hold, Republican incumbents became unpopular, and Democrats gained a net of eight seats, although Republicans retained control of the chamber.

The Republicans only gained one seat by defeating incumbent Daniel F. Steck (D-IA). The Democrats took open seats in Colorado, Illinois, Massachusetts, and West Virginia, and defeated five incumbents:

Henry J. Allen (R-KS)

John M. Robsion (R-KY)

Roscoe C. McCulloch (R-OH)

William B. Pine (R-OK)

William H. McMaster (R-SD)

This was the first of four consecutive Senate elections in the Depression in which Democrats made major gains, achieving a cumulative gain of 37 seats.
