The 2018 United States House of Representatives elections in Iowa were held on November 6, 2018, to elect the four U.S. representatives from the State of Iowa, one from each of the state's four congressional districts. The elections coincided with the gubernatorial election, as well as other elections to the House of Representatives, elections to the United States Senate, and various state and local elections. The state congressional delegation flipped from a 3–1 Republican majority to a 3–1 Democratic majority.

This was the first time the Democrats won the majority of Iowa's seats since 2010, and the first time they won the popular vote in the state since 2012. As of 2024, these results were also the last time the Democrats would achieve either due to Iowa's transition into a safe red state.
