The 2020 United States Senate election in Delaware was held on November 3, 2020, to elect a member of the United States Senate to represent the State of Delaware, 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 Chris Coons ran for reelection to a second full term and won against Republican challenger Lauren Witzke with 59.4% of the vote. He outperformed Democratic presidential nominee and former Delaware Senator Joe Biden (whose seat Coons was elected to in a 2010 special election) by 0.7 percentage points, compared to the concurrent presidential election. Coons also won Kent County, a swing county, for the first time in his senatorial career.

Prior to the election, Chris Coons' re-election was considered to be a near certainty regardless of the Republican challenger. The choice of Lauren Witzke, a controversial extremist and believer of QAnon, as the nominee, only cemented this prediction. Networks declared Coons the winner as soon as voting ended, based on exit polling alone. Coons also outperformed Biden (who also once held this Senate seat) in terms of percentage, but underperformed in terms of raw vote, likely due to the lack of third-party Senate candidates.
