The 1942 United States Senate election in Wyoming was held on November 3, 1942. Democratic Senator Harry Schwartz ran for re-election to his second term. He was challenged by businessman Edward V. Robertson, who emerged from a close and hotly contested Republican primary as the narrow winner. Aided in part by the national swing toward Republicans in 1942, Robertson defeated Schwartz for re-election by a decisive margin.
