The 2024 United States Senate election in Pennsylvania was held on November 5, 2024, to elect a member of the United States Senate to represent the state of Pennsylvania. Incumbent Democratic Senator Bob Casey Jr lost re-election to a fourth term, being defeated by Republican nominee David McCormick in an upset.[1] The primary election took place on April 23, 2024.[2] The election was considered essential for Democrats' chances to retain their majority in 2024.[3]

The Associated Press and Fox News declared McCormick the winner on November 7,[4] while Decision Desk HQ called the race for McCormick on November 14.[5] CNN, NBC, ABC, and CBS all called the race for McCormick on November 21; Casey conceded the race later that day.[6]

This was Pennsylvania's closest US Senate election since the passage of the Seventeenth Amendment, as well as the closest senate election of the 2024 cycle. Notably, the margin of just 0.25% between the Republican and Democratic candidates is less than the votes received by either the Libertarian candidate, John Thomas (1.29% of the vote), the Green candidate, Leila Hazou (0.95% of the vote), or the Constitution candidate, Marty Selker (0.34% of the vote).

With Kamala Harris's loss to Republican Donald Trump in the state's concurrent presidential election, this would be the first time since 1880 where Pennsylvania Democrats lost the state's electoral votes as well as an incumbent senator.

A recount confirmed the result of the election.[7]
