The 2022 United States Senate election in Iowa was held on November 8, 2022, to elect a member of the United States Senate to represent the State of Iowa. Incumbent Republican Senator Chuck Grassley defeated Democratic nominee Michael Franken to win re-election to an eighth term.{{Cite web |title=Chuck Grassley Defeats Mike Franken, Wins Eighth Senate Term |url=https://nz.news.yahoo.com/chuck-grassley-defeats-mike-franken-035134865.html |access-date=November 9, 2022 |website=nz.news.yahoo.com |date=November 9, 2022 |language=en-NZ}}

Grassley was first elected in 1980 and was most recently re-elected in 2016. Grassley, who turned 89 years old on September 17, 2022, ran for reelection to an eighth term. With U.S. Senator Patrick Leahy retiring the same year, he became the second-oldest person ever to be re-elected for another term (behind Strom Thurmond in 1996 at age 93), on January 3, 2023, upon the departure of Patrick Leahy from the United States Senate Chuck Grassley became the most senior member in the Senate, and on January 4, 2023, he became the longest-serving Republican senator in history (overtaking Orrin Hatch), as well as the most senior member of Congress since January 3, 2023.

Despite his victory, this was Grassley's closest Senate race since he was first elected in 1980 and worst performance as he did not crack 60% of the vote. Franken also beat Grassley in Linn, Story, and Polk counties, all of which Grassley had won in every election since 1986. In addition, this election was the first time that Grassley lost Black Hawk County. This election also saw the Class III seat's worst performance by a Republican since 1962, and best performance by a Democrat since 1980.
