The 2026 U.S. House elections in Iowa, held on November 3, 2026, will determine the state's four congressional representatives, with primaries already concluded on June 2, 2026. In the 1st District, Republican incumbent Mariannette Miller-Meeks, who secured the narrowest House win of 2024 with 50% of the vote, will face a rematch against Democrat Christina Bohannan. The 2nd District is an open seat since Republican Ashley Hinson gave it up to run for the U.S. Senate, pitting former state representative Joe Mitchell (R) against state representative Lindsay James (D). Meanwhile, in the 3rd District, Republican incumbent Zach Nunn will defend his seat against Democratic state senator Sarah Trone Garriott. These races feature significant primary battles, including several withdrawals and disqualifications, and will be crucial in determining the balance of power in the closely divided U.S. House.
