The 2022 United States Senate election in Arizona was held on November 8, 2022, to elect a member of the United States Senate to represent the state of Arizona.
The seat was previously held by Republican John McCain, who won his final term in 2016 and died from glioblastoma on August 25, 2018. Governor Doug Ducey appointed former U.S. Senator Jon Kyl to fill the seat. Kyl resigned at the end of that year and Ducey replaced him with Martha McSally, who then lost to Democrat Mark Kelly in 2020.
Primaries in Arizona took place on August 2, 2022. Kelly won renomination without opposition, while venture capitalist Blake Masters won the Republican nomination against a large field of candidates. Although Arizona typically leans Republican, Kelly led Masters by low single digits in aggregate polling. Kelly held a significant fundraising advantage until many Republican-aligned groups began spending to assist Masters in the final weeks of the campaign. On November 1, Libertarian nominee Marc Victor dropped out of the race and endorsed Masters.
Kelly won re-election, defeating Masters by a comfortable margin of about 5 points. This was the first time Democrats won a full term to this seat since 1962. The 2022 race was competitive and seen as crucial to determining party control of the U.S. Senate; with Kelly's victory in Arizona and a Democratic victory in Nevada, in addition to a Democratic gain in Pennsylvania, it was projected on November 12 that the Democratic caucus would retain control of the Senate in the 118th United States Congress. Masters conceded the race to Kelly on November 15, 2022.

## General election

In what was initially expected to be one of the most widely contested elections in the nation, Kelly amassed a massive fundraising advantage over Masters, raising a record $75 million compared to Masters's $12 million. Due to the Supreme Court's Dobbs v. Jackson Women's Health Organization decision, which reversed Roe v. Wade, Kelly spent the campaign heavily attacking Masters over his anti-abortion stance, which was seen as hurting Masters especially among women voters. He also attacked Masters's support for privatizing Social Security, as Arizona has many retired seniors who use the program. Masters's claim that the 2020 presidential election was stolen also hurt him among voters. Steven J. Law, the leader of a Republican-aligned super PAC, said that Masters "had scored the worst focus group results of any candidate he had ever seen," and cancelled all of its Arizona television advertisements supporting Masters to divert money to other races.
With the limited amount of money he had, Masters attempted to portray Kelly as weak on illegal immigration, supportive of spending programs that caused inflation, and too supportive of President Joe Biden. In the final weeks of the campaign, Republican groups increased the amount of money they were spending on the race and polls began to tighten, and many news outlets moved the race from lean Democrat to tossup. However, in the end, Kelly relatively easily defeated Masters, which helped Democrats in retaining the Senate. According to Ron Brownstein of CNN in 2023, Kelly won independent voters by double-digit margins, which contributed to Masters's defeat.
