The 2022 Washington State Senate elections took place as part of the biennial United States elections. Washington state voters elected state senators in 26 of the state's 49 Senate districts. The other 23 state senators were not up for re-election until the next biennial election in 2024. State senators served four-year terms in the Washington State Senate. A top two primary election in August 2022 determined which candidates appear on the November 6 general election ballot. Each candidate was allowed to write in their party preference so that it appeared as they desired on the ballot.
