The 2022 United States House of Representatives election in Delaware was held on November 8, 2022, to elect the U.S. representative from Delaware's at-large congressional district. The election coincided with other elections to the House of Representatives, elections to the United States Senate and various state and local elections. The incumbent Democrat Lisa Blunt Rochester won re-election to a fourth term.

The election had very low turnout and was the worst performance for the Democratic candidate since 2008 when incumbent Republican representative Mike Castle won reelection in a landslide. This was also the closest House race in the state since 1982.
