The 2018 United States House of Representatives elections in Minnesota were held on November 6, 2018, to elect the eight U.S. representatives from the state of Minnesota, one from each of the state's eight congressional districts. The elections coincided with an open gubernatorial election, a U.S. Senate election, a special U.S. Senate election, State House elections, and other elections.
In the 2018 elections, Democrats gained the 2nd and 3rd districts from Republican incumbents, and the Republicans gained the 1st and 8th districts from Democrats running for higher office, leaving party representation in Minnesota's House delegation unchanged at five members from the DFL and three members from the GOP.
