2020 New Hampshire Senate election

The 2020 New Hampshire Senate elections took place as part of the biennial 2020 United States elections. New Hampshire voters elected state senators in all of the state's 24 senate districts. State senators serve two-year terms in the New Hampshire Senate, with all of the seats up for election each cycle. The primary elections on September 8, 2020, determined which candidates will appear on the November 3, 2020, general election ballot.

Following the 2018 election, Democrats had control of the New Hampshire Senate with 14 seats to Republicans' 10 seats. Following the 2020 election, the Republicans flipped four seats and thus control of the chamber alongside flipping the New Hampshire House of Representatives.
