The 2018 Arizona gubernatorial election took place on November 6, 2018, to elect the governor of Arizona. It was held concurrently with the election of Arizona's Class I U.S. Senate seat, as well as elections for Arizona's congressional seats and various state and local elections.
The primary was held on August 28. Despite considerably closer contests in other Arizona state elections, which included Democratic gains for U.S. Senate, Secretary of State, and Superintendent of Public Instruction, incumbent Governor Doug Ducey won a second term, with a slightly increased majority from his 2014 win and the largest margin of victory of any statewide candidate on the ballot.
