The 2006 Tennessee gubernatorial election was held on November 7, 2006. Incumbent Democratic governor Phil Bredesen, defeated Republican State Senator Jim Bryson in a landslide to win a second term as Governor of Tennessee, winning every county in the state.
As of 2022, it is the last time a Democrat won a majority of counties in the state, the last time a Democrat won any statewide race in Tennessee, and the most recent statewide election in Tennessee in which 88 of the state's 95 counties, including Knox County and Hamilton County, went to the Democratic candidate. Only Davidson, Shelby, Haywood, Hardeman, Houston, Jackson, and Lake counties have voted for a Democratic candidate in a Presidential, Senate, or gubernatorial race since 2006, with Jackson and Lake only going Democratic once. Eight years later, Republican Governor Bill Haslam won every county in the state in his re-election campaign, marking a sharp political shift in the state.
