The 2024 United States Senate election in Wyoming was held on November 5, 2024, to elect a member of the United States Senate to represent the state of Wyoming. Incumbent Senator John Barrasso was appointed to the Senate in 2007 after Craig Thomas died. Barrasso won a 2008 special election to complete Thomas' term and won full terms in 2012 and 2018. He was seeking a third full term and declared his intent to run for Assistant Republican Leader at the end of the year. Primary elections took place on August 20, 2024. Wyoming has been represented in the U.S. Senate exclusively by Republicans since 1977, and Barrasso was heavily favored to win another term.

Having won renomination with more than 67% of the vote, Barrasso was easily re-elected with over 75% of the vote in the general election, defeating Democrat Scott Morrow, carrying every county except Teton, and flipping Albany. Barrasso overperformed Republican Donald Trump in the concurrent presidential election by 4.51%. This was the largest margin of victory in any U.S. Senate election since North Dakota in 2016, and it represented a significant improvement from Barrasso's 2018 performance, which was the weakest in his Senate career and the closest a Democrat ever came to winning a Senate seat in the state since 1996.
