A general election was held in the U.S. state of Arizona on November 6, 2018. All of Arizona's executive offices were up for election as well as a United States Senate seat and all of Arizona's nine seats in the United States House of Representatives. The Republican Party won the majority of statewide offices, albeit by much narrower margins than in previous elections (except for the governorship, which they won easily), while the Democratic Party picked up three statewide offices.

## U.S. Senate

Incumbent Republican Jeff Flake was eligible to run for re-election to a second term. As a strong critic of President Donald Trump and remaining unpopular in the state, Flake announced in October 2017 that he would not seek reelection.
President Trump and Republicans backed Martha McSally to succeed Flake. Kelli Ward, former state senator and candidate for the U.S. Senate in 2016 also ran for the Republican nomination for the open seat.

### Results

On the evening of Monday, November 12, 2018, McSally posted on her Twitter that she had spoken with Sinema and conceded. Sinema celebrated with supporters later that evening.
