The 2024 Washington Republican presidential primary were held on March 12, 2024, as part of the Republican Party primaries for the 2024 presidential election. 43 delegates to the 2024 Republican National Convention were allocated on a proportional basis.[1] The contest was held alongside primaries in Georgia, Hawaii, and Mississippi.
Washington was the tipping point state which brought the delegates pledged to Donald Trump to a majority, securing the former president the Republican nomination for the third consecutive time, and making Trump the only person apart from Richard Nixon to be the Republican nominee more than twice.[2]
