The 1918 United States Senate election in Mississippi was held on November 3, 1918. Incumbent Democratic U.S. Senator James K. Vardaman ran for re-election to a second term in office, but was defeated in the Democratic primary by U.S. Representative Pat Harrison.

Because Harrison faced only nominal opposition in the general election, his victory in the August 20 primary was tantamount to election.
