The 2026 United States Senate election in New Mexico will be held on November 3, 2026, to elect a member of the United States Senate to represent the state of New Mexico. Democratic incumbent Ben Ray Luján is seeking a second term. He is being challenged by Republican former oil and gas operator Larry Marker.

Primary elections were held on June 2. Luján won the Democratic nomination with 83.7% of the vote against minimal opposition. After no Republicans qualified for the primary ballot, Marker was nominated as a write-in candidate.

Republicans have not won a Senate election in New Mexico since 2002.

Democratic primary Ben Ray Luján, a member of the Luján political family, was elected in 2020 after serving as the representative for the 3rd congressional district from 2009 until 2021. During his tenure in the Senate, Luján has been an outspoken critic of Donald Trump, having voted in line with Trump's stated position only 5% of the time. Luján was widely considered the favorite in the primary election.

Luján's sole opponent in the primary is Matt Dodson, a U.S. Air Force veteran from Farmington. A self-described democratic socialist, Dodson had previously ran unsuccessfully for local and state offices. Originally failing to achieve the 20% threshold of votes in the Democratic Party convention, he qualified for the ballot through signature collection.

Dodson is currently suspended from the state Democratic Party, and had previously accused San Juan County party chair Mary Schildmeyer of embezzling funds. He denied the allegations, and charges were dropped due to lack of evidence. On April 8, 2026, Dodson was arrested in Otero County after blocking the entrance road to Holloman Air Force Base during an anti-drone warfare protest. He was released two days later.
