2020 United States House of Representatives election in Montana
The 2020 United States House of Representatives election in Montana was held on November 3, 2020, to elect the U.S. representative from Montana's at-large congressional district. The election coincided with the 2020 U.S. presidential election, as well as other elections to the House of Representatives, elections to the United States Senate, and various state and local elections.
The incumbent, Republican Greg Gianforte, who was reelected with 50.9% of the vote in 2018, declined to run for reelection and instead ran successfully for Governor of Montana, after having lost the 2016 election to incumbent Democrat Steve Bullock.
As the Green Party was removed from the ballot, this was the first time since 1988 that there were no non-Republican or Democratic candidates running for either United States House of Representatives or United States Senate in Montana.
In the general election, Republican state auditor Matt Rosendale defeated former state representative Kathleen Williams.
As of a result of the 2020 redistricting cycle, Montana regained its 2nd congressional district that it lost in 1993, therefore making the 2020 election the last election for the at-large district before it was eliminated.
