Iowa's congressional districts



Iowa is divided into four congressional districts, each represented by a member of the United States House of Representatives. The state's congressional map is roughly divided by quadrants in the northeast, northwest, southeast, and southwest sections of Iowa.

The districts were represented by three Republicans and one Democrat from the 2014 elections to the 2020 elections, with a brief period of Democratic control after the 2018 elections. In the 2022 elections, Republicans won every seat for the first time since the 1994 elections.
