Incumbent Kris Mayes (D) and Warren Petersen (R) are running in the general election for Attorney General of Arizona on November 3, 2026.

Mayes was elected in 2022 49.9%–49.9%. That year, Katie Hobbs (D) won the gubernatorial election 50.3%–49.6% and Mark Kelly (D) won the senatorial election 51.4%–46.5%. In 2024, President Donald Trump (R) defeated Kamala Harris (D) 52.2%–46.7% in the presidential election and Ruben Gallego (D) won the senatorial election 50.1%–47.7%.

Before her election as attorney general, Mayes was an attorney, journalist, and law professor. She served as a Republican member of the Arizona Corporation Commission from 2003 to 2010. In a post on X.com, Mayes said, "From day one, I’ve stayed focused on the work at hand — protecting Arizona families from drug smugglers and scammers, holding greedy corporations accountable, defending our water, and keeping our communities safe. That work isn’t done."

Petersen has been a member of the Arizona Legislature since 2013, alternating between the House and Senate. He has represented the 12th District in the Arizona Senate since 2021. He represented the 12th District in the Arizona House of Representatives from 2019 to 2021. From 2017 to 2019, he represented the 12th District in the Arizona Senate. From 2017 to 2013, he represented the 12th District in the Arizona House of Representatives. Petersen's campaign website says, "As Senate President, I stood up for Arizona families by defending state laws when others refused, like ensuring fairness in women’s sports. I’ve led the charge against unconstitutional mandates, fought for our Second Amendment rights, and worked to keep government in check."

The Arizona Mirror's Gloria Rebecca Gomez wrote, "Mayes has marked her time in office by opposing Trump administration policies and joining dozens of lawsuits aimed at blocking them — especially the White House’s mass deportation campaign, and defending access to abortion care in the wake of the state’s abortion rights amendment. Meanwhile, Petersen has vowed to uphold Trump’s political agenda and mobilized his position as the head of the Arizona Senate for the last three years to intervene in lawsuits on behalf of laws that Mayes refused to defend, including a near-total abortion ban from 1864 and the state’s trans athletic ban."

This election, along with the elections for governor and secretary of state, will determine Arizona's triplex status. Democrats currently hold all three triplex offices, making Arizona a Democratic triplex. If all three Democratic incumbents are re-elected, Democrats will maintain their triplex in Arizona. If all three Republican challengers win, Republicans will gain a triplex in Arizona. A mixed outcome would result in neither party having a triplex.

The Arizona Attorney General is the state's chief law enforcement officer, responsible for providing legal advice to the state government and both filing and defending lawsuits on behalf of the state. This is one of 30 attorney general elections taking place in 2026. Forty-three of 50 states hold elections for attorney general.
