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, concurrently with other elections to the U.S. Senate, elections to the United States House of Representatives and other state and local elections. Primary elections will be held on June 2, 2026. Incumbent Democratic Senator Ben Ray Luján is seeking election to a second full term. Luján was elected to his first full term with 51.73% of the vote in 2020 to succeed retiring Democratic Senator Tom Udall.
New Mexico is considered to be a moderately blue state at the federal and state levels. Kamala Harris won the state by 6 percentage points in the 2024 presidential election, while the last time a statewide race was won by a Republican was in 2016, when Judith Nakamura won re-election to the state's Supreme Court. The most recent election for this seat, held in 2020, saw Democrat Ben Ray Luján win his first term in the Senate by six points over Republican Mark Ronchetti.
Democrats currently control all statewide executive offices, the entire congressional delegation, and majorities in both state legislative chambers. New Mexico has not voted for the Republican presidential nominee since 2004, and last voted for a Republican senator in 2002.

Christopher Heuvel, the only Republican to file for the race, was disqualified for failing to meet the requirements to appear on the ballot. The Republican Party had an opportunity to field a prospective candidate until March 17 to collect the signatures needed to qualify for the nomination as a write-in, which was successfully done by former oil and gas operator Larry Marker. Marker must receive 2,351 write-in votes in the primary to advance to the general election.
