The 2020 Utah gubernatorial election was held on November 3, 2020, to elect the governor of Utah. Incumbent Republican governor Gary Herbert declined running for re-election to a third full term.

## Background

Although incumbent Republican governor Gary Herbert was eligible to run for re-election to a third full term, he initially announced shortly after being re-elected in 2016 that he would not run again, but indicated in January 2019 that he was open to the possibility of running again before ultimately deciding to retire and endorse his lieutenant governor, Spencer Cox. Utah had not had a Democratic governor since Scott M. Matheson left office in January 1985. This is the second longest active streak of one-party leadership, trailing only South Dakota, which had not had a Democratic governor since Harvey L. Wollman left office in 1979.
The primaries took place on June 30, 2020. The filing deadline was on June 19, 2020.

## Description

The 2020 Utah gubernatorial election was held on November 3, 2020, to elect the governor of Utah, concurrently with the 2020 U.S. presidential election, as well as elections to the United States Senate and elections to the United States House of Representatives and various state and local elections.
The winner of the election was the first non-incumbent gubernatorial candidate to be elected since Jon Huntsman Jr. in 2004, who ran in this election before he was eliminated in the primaries.
Lieutenant Governor Spencer Cox won the general election by defeating the Democratic nominee, University of Utah law professor and former CFPB official Christopher Peterson. This election was the first open-seat gubernatorial election in Utah since 1992.
