The 2018 Iowa elections were held in the U.S. state of Iowa on November 6, 2018. A closed primary election was held on June 5, 2018. All of Iowa's executive officers were up for election, as well as all four of Iowa's seats in the United States House of Representatives, 25 (half) of the seats in the Iowa Senate, and all 100 seats in the Iowa House of Representatives.

Incumbent Republican governor Terry Branstad, who had served for two consecutive and six total terms as Iowa governor, resigned to be the United States Ambassador to China in 2017. Lieutenant Governor Kim Reynolds assumed the governorship and was seeking a full term.

Incumbent Democratic attorney general Tom Miller had served in the position since 1995, and previously from 1979 to 1991. The Republican Party did not nominate anyone, but the Libertarian Party nominated Marco Battaglia.

• Deidre DeJear
• Jim Mowrer

• Paul Pate, incumbent

Incumbent Democratic state treasurer Michael L. Fitzgerald, who had served in the position since 1983, ran for reelection to a tenth term in office. Fitzgerald was unopposed in the primary and did not have a Republican challenger, but did have a challenger from the Libertarian party.

Incumbent Auditor Mary Mosiman, who had served since 2013, was eligible for re-election and was unopposed in the Republican primary. Attorney Rob Sand won the Democratic primary.

Republican Secretary of Agriculture Bill Northey had served in the position since 2007. Northey was considering running for Iowa governor, but after Governor Terry Branstad was nominated to be Ambassador to China, he announced he would not run. Northey had not ruled out running for reelection in 2018, but said he would be willing to serve as lieutenant governor instead if asked. In 2018, he was nominated by President Donald Trump to be Under Secretary of Agriculture for Farm and Foreign Agricultural Services, and subsequently ruled out reelection. The office was then held by Mike Naig, serving in an acting capacity.
