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. Incumbent three-term Democratic Senator Jeanne Shaheen declined to seek re-election to a fourth term.
This will be the first open Senate election in New Hampshire since 2010, and the first for this seat in which there is no incumbent running since 1990.

## Background

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, and was re-elected in 2014 and 2020.

## Democratic primary
### Candidates
#### Publicly expressed interest

* Annie Kuster, former U.S. representative for New Hampshire's 2nd congressional district (2013–2025) (if Pappas doesn't run)

#### Potential

* Maggie Goodlander, U.S. representative for New Hampshire's 2nd congressional district (2025–present)
* Chris Pappas, U.S. representative for New Hampshire's 1st congressional district (2019–present)
* Stefany Shaheen, former Portsmouth city councilor and daughter of incumbent Jeanne Shaheen

#### Declined

* Jeanne Shaheen, incumbent U.S. Senator (2009–present)

## Republican primary
### Candidates
#### Publicly expressed interest

* Scott Brown, former U.S. Ambassador to New Zealand and Samoa (2017–2020), former U.S. Senator from Massachusetts (2010–2013), and nominee for this seat in 2014
* Jack Franks, real estate developer
* Chris Sununu, former governor of New Hampshire (2017–2025) and brother of former U.S. Senator John Sununu

#### Potential

* Lou Gargiulo, former state representative (1992–1996)
* Corey Lewandowski, political strategist and former campaign manager for the Donald Trump 2016 presidential campaign
* Matt Mowers, former chair of the New Hampshire Republican Party, nominee for New Hampshire's 1st congressional district in 2020 and candidate in 2022
* Stephen Stepanek, former chair of the New Hampshire Republican Party (2019–2023) and former state representative (2014–2016)

#### Declined

* Kelly Ayotte, Governor of New Hampshire (2025–present) and former U.S. Senator (2011–2017)
