The 2020 United States Senate election in New Hampshire was held on November 3, 2020, to elect a member of the United States Senate to represent the State of New Hampshire, concurrently with the 2020 U.S. presidential election, as well as other elections to the United States Senate, elections to the United States House of Representatives and various state and local elections. Incumbent Democratic Senator Jeanne Shaheen won reelection to a third term after comfortably defeating Republican nominee Bryant Messner by 15.6 points and sweeping every single county in the state. This marked the first Senate election since 1972 in which the Democrat carried Belknap County.

Shaheen's final margin outperformed Democratic presidential nominee Joe Biden in the concurrent presidential election by around 8 percentage points while carrying two counties that voted for Donald Trump.

The primary election was held on September 8, 2020.
