The 2018 United States Senate election in Tennessee took place on November 6, 2018, concurrently with other elections to the United States Senate, elections to the United States House of Representatives and various state and local elections. Incumbent Republican senator Bob Corker opted to retire instead of running for a third term. Republican U.S. representative Marsha Blackburn won the open seat, defeating former Democratic governor Phil Bredesen.
The primaries took place on August 2, 2018, with Blackburn and Bredesen winning their respective party nominations.
Early in the campaign, Bob Corker said that Blackburn's opponent, Democrat Phil Bredesen, was "a very good mayor, a very good governor, a very good businessperson", that he had "real appeal" and "crossover appeal", and that the two of them had cooperated well over the years. However, Corker said he would vote for Blackburn and donate to her campaign, and questioned whether Bredesen would be able to win a Senate seat in a red state like Tennessee. After Corker's praise for Bredesen, Senate Majority Leader Mitch McConnell warned Corker that such comments could cost the Republican Party its Senate majority. Shortly after Corker's comments, Trump tweeted an endorsement of Blackburn.
In October 2018, Tennessean singer-songwriter Taylor Swift endorsed Bredesen. The endorsement was notable given that Swift had previously been publicly apolitical, but spoke out because Blackburn's voting record in Congress "appalled" and "terrified" her. Swift shared a link to the nonpartisan voter registration website Vote.org, which saw a significant spike in page views and new registrations. Donald Trump criticized Swift's endorsement.
This election was expected to be among the most competitive Senate races in 2018, with CNN calling it the single most important Senate race in the country. Polls showed the race as close until the confirmation hearings for Supreme Court Justice Brett Kavanaugh started, which many Tennesseans believed the Democratic Party handled poorly. This is believed to have mobilized Republican voters and cost Bredesen any chance of winning. Bredesen also announced his support for Kavanaugh, which some believe cost him supporters.
This was Tennessee's closest Senate race since 2006, with Blackburn winning by a 10.8% margin.

### Speculation surrounding Senator Corker

On September 26, 2017, Republican senator Bob Corker announced that he would not seek another term in 2018. Many called on Corker to reverse his decision to retire. Former U.S. representative Fincher dropped out of the race, calling on Corker to jump back in and challenge U.S. representative Blackburn for the GOP nomination. Fincher said in a statement that the GOP should unite "behind a candidate who can win" the general election. Blackburn said she would remain in the race even if Corker reversed his decision. Amid the speculation about Corker's decision, many of Tennessee's Republican politicians, including many in the Tennessee General Assembly, reiterated their support for Blackburn. Corker's chief of staff announced on February 27, 2018, that Corker would stick with his plan to retire.

### Results

On November 6, 2018, Blackburn defeated Bredesen in the general election, carrying all but three counties, the largest number of counties ever won in an open senate election in Tennessee. Although polls began to show the race in Blackburn's favor following the Kavanaugh hearings, Blackburn won by a larger margin than all but one poll showed.
