The 2024 United States Senate election in Washington was held on November 5, 2024, to elect a member of the United States Senate to represent the state of Washington. Democratic incumbent Senator Maria Cantwell was elected to her fifth term, winning over Republican physician Raul Garcia.

Cantwell improved on her prior 2018 performance despite the Republican national environment. She won 59.09% of the vote, up from 58.43% in 2018 and marking a 1.6% leftward shift from that race. Washington had the smallest swing of any state in the concurrent presidential race, swinging rightward by under 1% from 2020.

Cantwell slightly outperformed Kamala Harris in the concurrent U.S. presidential election in Washington, winning Pacific County which also voted for Donald Trump. Cantwell won by a margin of 18.45%, narrowly higher than Harris's 18.22% margin.

Primary election The blanket primary election was held on August 6, 2024.
