2018 United States House of Representatives elections in New Mexico

The 2018 United States House of Representatives elections in New Mexico were held on November 6, 2018, to elect the three U.S. representatives from the state of New Mexico, one from each of the state's three congressional districts. The elections coincided with the gubernatorial election, as well as other elections to the House of Representatives, elections to the United States Senate and various state and local elections.
