The 2020 United States Senate election in New Mexico was held on November 3, 2020, to elect a member of the United States Senate to represent the State of New Mexico, concurrently with the 2020 U.S. presidential election, as well as other elections to the United States Senate in other states, elections to the United States House of Representatives, and various state and local elections.

On March 25, 2019, incumbent Democratic Senator Tom Udall announced that he would retire. Udall was the only Democratic senator who did not run for reelection in 2020. Democratic U.S. Representative Ben Ray Luján defeated Mark Ronchetti by a 6.1% margin. Luján underperformed Democratic presidential nominee Joe Biden by 4.6%, who won the concurrent presidential election in the state against President Donald Trump by 10.8%. Luján was the first Hispanic to have won a Senate seat in New Mexico since Joseph Montoya in 1970.
