The 1924 United States Senate election in Minnesota took place on November 4, 1924. Republican U.S. Representative Thomas D. Schall defeated incumbent Farmer–Labor U.S. Senator Magnus Johnson and Democratic challenger John J. Farrell. Johnson, who was elected in the 1923 special election, had been in office for less than a year and a half when his attempt to win a full six-year term was defeated by Schall.
