The 2020 Washington State Senate elections took place as part of the biennial 2020 United States elections. Washington voters elected state senators in 26 of the 49 state legislative districts. Elections to the Washington State Senate were held on November 3, 2020.
Following the previous election in 2018, Democrats held a 28-seat majority in the Senate, compared to Republicans' 21 seats. Senators who did not run for re-election were Randi Becker,[1] Maureen Walsh,[2] and Hans Zeiger[3] (all Republicans).
Democrats retained control of the Washington State Senate following the 2020 general election, with the balance of power remaining unchanged: 28 (D) to 21 (R).[4]
