The 2026 United States House of Representatives elections in Montana were held on November 3, 2026, to elect the two U.S. representatives from the state of Montana, one from each of the state's 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 primary elections took place on June 2, 2026. Montana, Maine, and Wisconsin will be the three states with evenly split congressional delegations following the 2026 House of Representatives elections, (1 - 1, 1 - 1, and 4 - 4 respectively.).

This was the first time Democrats won a U.S. House election in Montana since 1994.
