2020 United States Senate election in Oregon

The 2020 United States Senate election in Oregon was held on November 3, 2020, to elect a member of the United States Senate to represent the State of Oregon, concurrently with the 2020 U.S. presidential election, as well as other elections to the United States Senate, elections to the United States House of Representatives and various state and local elections. Incumbent Democratic senator Jeff Merkley won reelection to a third term in office. Although this Senate seat was largely expected to be one of the safest for the Democrats, the race received national attention due to the Republican nominee Jo Rae Perkins's promotion of the unfounded QAnon conspiracy theory. Furthermore, Perkins had flipped five counties that Merkley had won in 2014 (though only by pluralities in the cases of Jackson, Polk and Yamhill).
