The 1932 United States Senate election in Washington was held on November 8, 1932. Incumbent Republican U.S. Senator Wesley Livsey Jones ran for a fifth term in office, but was defeated by former State Representative Homer Bone.
Bone defeated Jones in a landslide. The percentage margin of 27.9 points may be the largest for any incumbent major-party nominee in Senate history. Jones died on November 19, less than two weeks after the election.
