The 1948 United States Senate election in Iowa took place on November 2, 1948. Incumbent Republican Senator George A. Wilson ran for re-election to a second term but was defeated by Democratic former Senator Guy Gillette who successfully sought a comeback. Wilson being perceived as an ineffective senator along with the lack of prominent Republican allies to back his re-election bid contributed to his landslide defeat.
