2018 Arizona Secretary of State election

The 2018 Arizona Secretary of State election took place on November 6, 2018, to elect the Secretary of State of Arizona, concurrently with the election of Arizona's Class I U.S. Senate seat, as well as other elections to the United States Senate in other states and elections to the United States House of Representatives and various state and local elections.

Incumbent Michele Reagan was first elected in 2014 and ran for re-election. She was defeated in the Republican primary by Steve Gaynor. State senator Katie Hobbs defeated Gaynor in the general election by a small margin, becoming the first Democratic Secretary of State since Richard Mahoney was elected in 1990.

The race was rated "Likely Republican" by Governing.com, but this did not come to fruition as Katie Hobbs pulled off an upset win which, alongside Democrats' victory in the concurrent Senate election, established Arizona's role as a key battleground state.
