Who are my U.S. senators in Iowa?
Iowa's two current U.S. senators are: Chuck Grassley (R) — serving since 1981 Joni Ernst (R) — serving since 2015 One heads-up: Ernst announced she's not seeking re-election in 2026, so Republican Ashley Hinson and Democrat Josh Turek are the nominees to replace her in the November 3, 2026 election. Grassley isn't up for re-election this cycle, so for now both remain your sitting senators. Wikipedia
