The 2026 United States Senate election in New Hampshire will be held on November 3, 2026, to elect a member of the United States Senate to represent the state of New Hampshire. Primary elections will be held on September 8, 2026. Incumbent three-term Democratic Senator Jeanne Shaheen declined to seek a fourth term.
This will be the first open Senate election in New Hampshire since 2010, and the first for this seat since 1990.
New Hampshire is considered to be a slightly to moderately blue state at the federal level, with Kamala Harris carrying the state by roughly 3 percentage points in the 2024 presidential election. The state's congressional delegation has been entirely Democratic since 2017. However, Republicans control the governorship, both state legislative chambers, and a majority in the executive council.
Shaheen was first elected in 2008, defeating then-incumbent senator John Sununu in a rematch of 2002, and was re-elected in 2014 and 2020. Republicans have not won a U.S. Senate race in New Hampshire since 2010.
