Iowa Congressional District Map
Iowa congressional district boundaries divide the state into four US House seats, and this wall map draws every line against all 99 counties, each county seat, and the capital at Des Moines.
- IA-1: the southeastern quadrant, including Davenport in Scott County and Iowa City in Johnson County
- IA-2: northeast Iowa around Cedar Rapids, Waterloo, and Dubuque, anchored by Linn and Black Hawk counties
- IA-3: Des Moines and Polk County west through Council Bluffs and Pottawattamie County
- IA-4: the rural northwest, from Sioux City and Woodbury County across to Ames and Story County
- Boundaries from the 2020 redistricting cycle, in force for the 2026 election and the 2027 to 2029 120th Congress
- Metropolitan and micropolitan area centers labeled statewide
Map Shop prints this title in house using non-partisan colors, so nobody reads a party message into the fill. Government affairs teams follow the four-member Iowa delegation from it, county party offices in Cedar Rapids and Council Bluffs mark precinct turf on the laminated finish, and civics teachers show students how one rural seat can cover half the state.
