The 2018 United States House of Representatives elections in Wisconsin were held on November 6, 2018, to elect the eight U.S. representatives from the state of Wisconsin, one from each of the state's eight congressional districts. The elections coincided with other elections to the House of Representatives, elections to the United States Senate, and various state and local elections. The Wisconsin partisan primary was held on August 14, 2018, with the governor, U.S. senator, U.S. representative, odd-numbered Wisconsin State Senate seats, and all Wisconsin Assembly seats on the ballot.
Wisconsin was notable for being the only state in which the party that won the popular vote still held a minority of congressional seats in 2018. The Milwaukee Journal Sentinel attributed this to the impact of gerrymandering imposed by the Republican-controlled Wisconsin Legislature in 2011.
