The 2020 United States Senate elections were held on November 3, 2020, with the 33 class 2 seats of the Senate contested in regular elections. Of these, 21 were held by Republicans, and 12 by Democrats. The winners were elected to 6-year terms from January 3, 2021, to January 3, 2027. Two special elections for seats held by Republicans were also held in conjunction with the general elections: one in Arizona, to fill the vacancy created by John McCain's death in 2018; and one in Georgia, following Johnny Isakson's resignation in 2019. These elections ran concurrently with the 2020 United States presidential election in which incumbent president Donald Trump lost to Democratic nominee Joe Biden.

In the 2014 United States Senate elections, the last regularly scheduled elections for Class 2 Senate seats, the Republicans won nine seats from the Democrats and gained a majority, which they continued to hold after the 2016 and 2018 elections. Before the elections, Republicans held 53 seats, Democrats held 45 seats, and independents caucusing with the Democrats held two seats, neither of which were up for re-election. Including the special elections in Arizona and Georgia, Republicans defended 23 seats, and the Democrats defended 12.

In this election, the Democratic Party made a net gain of three Senate seats and the vice presidency, giving them a majority for the first time since 2014, albeit by a narrow 50–50 margin. Democrats unseated four Republicans in Arizona, Colorado, and both elections in Georgia – while Republicans flipped a seat in Alabama; however, Democrats under-performed expectations overall; despite record-breaking turnout and fund-raising efforts, they failed to flip several seats that were considered competitive, and lost many races by much larger margins than expected. Except in Maine, the winning party in every Senate election was the winning party in the state's presidential election.

Due to election laws in Georgia that require candidates to win at least 50% of the vote in the general election, the state's regularly scheduled and special Senate elections were decided in run-off elections on January 5, 2021. After the November general election, Republicans held 50 seats, while Democrats held 48 and the vice presidency, so sweeping both races was crucial for Democrats to attain a majority. They succeeded in doing so, and the partisan balance in the Senate became tied for the third time in history, after the results in the 1880 elections and the 2000 elections. Vice President Kamala Harris's tie-breaking vote gave Democrats control of the chamber by the smallest margin possible after the new administration took office.

This marked the first time since 1980 that either chamber of Congress flipped partisan control in a presidential election year, and the first time Democrats did so since 1948.

Change in composition

Republicans defended 23 seats, while Democrats defended 12. Each block represents one of the 100 Senate seats. "D#" is a Democratic senator, "I#" is an independent senator, and "R#" is a Republican senator. They are arranged so that the parties are separated, and a majority is clear by crossing the middle.

Before the elections

Each block indicates an incumbent senator's actions going into the election. Both Independents caucus with the Democrats.

After the elections

After the January 5, 2021 runoff elections in Georgia.

Final pre-election predictions

Several sites and individuals published predictions of competitive seats. These predictions looked at factors such as the strength of the incumbent (if the incumbent was running for re-election) and the other candidates, and the state's partisan lean (reflected in part by the state's Cook Partisan Voting Index rating). The predictions assigned ratings to each seat, indicating the predicted advantage that a party had in winning that seat. Most election predictors used:

• "tossup": no advantage
• "tilt" (used by some predictors): advantage that is not quite as strong as "lean"
• "lean": slight advantage
• "likely": significant, but surmountable, advantage
• "safe" or "solid": near-certain chance of victory

U.S. senator before election Doug Jones Democratic Elected U.S. senator Tommy Tuberville Republican

Incumbent Democrat Doug Jones was elected in a special election in 2017, narrowly defeating Republican nominee Roy Moore. He ran for a full term in 2020, losing to Republican Tommy Tuberville in a landslide.

Tuberville is a former football head coach for Auburn University. He defeated former senator and attorney general Jeff Sessions in a July 14 run-off to secure the Republican nomination, after securing President Donald Trump's endorsement. Sessions occupied the seat until 2017 when he resigned to become attorney general in the Trump administration.

Alabama is one of the country's most Republican states, and Jones's win was in part due to sexual assault allegations against nominee Roy Moore during the special election; most analysts expected the seat to flip back to GOP control. Tuberville defeated Jones by more than 20 percentage points.

U.S. senator before election Dan Sullivan Republican Elected U.S. senator Dan Sullivan Republican

One-term Republican Dan Sullivan was elected in 2014, defeating incumbent Democrat Mark Begich. He defeated independent challenger Al Gross to win a second term in office.

Potential Democratic candidates included Begich, who was the Democratic nominee for governor of Alaska in 2018, and Anchorage mayor Ethan Berkowitz, who was the Democratic nominee for governor of Alaska in 2010. One Democrat, Edgar Blatchford, filed to run by the June 1 filing deadline.

Gross, an orthopedic surgeon and fisherman, declared his candidacy on July 2, 2019, as an independent. He participated in a joint primary for the Alaska Democratic Party, Alaska Libertarian Party and Alaskan Independence Party, winning the nomination as an independent supported by the Democratic Party.

Despite predictions of a close race, Sullivan defeated Gross by 12.7 percentage points.

U.S. senator before election Martha McSally Republican Elected U.S. senator Mark Kelly Democratic

Six-term Republican John McCain was re-elected in 2016, but died in office on August 25, 2018, after a battle with brain cancer. Republican governor Doug Ducey appointed former senator Jon Kyl to fill the seat temporarily. After Kyl stepped down at the end of the year, Ducey appointed outgoing U.S. Representative Martha McSally to replace him after she lost the election to the other Arizona senate seat. McSally ran in the 2020 special election to fill the remaining two years of the term, losing to Democrat Mark Kelly, a former astronaut.

Once a solidly Republican state, Arizona trended more purple in the late 2010s. Incumbent Republican Martha McSally was appointed to the late John McCain's seat two months after losing the 2018 Arizona U.S. Senate election to Democrat Kyrsten Sinema. Her Democratic opponent, astronaut Mark Kelly, raised significantly more money and generally led her by 5 to 15 points in the polling. McSally also suffered from low approval ratings due to her strong allegiance to Trump, who was unpopular in Arizona despite having won the state by 3.5 points in 2016.

One-term Republican Tom Cotton was elected in 2014, after serving two years in the United States House of Representatives, defeating incumbent Democratic senator Mark Pryor by a comfortable margin. Cotton was re-elected to a second term by a 33-point margin, defeating Libertarian Ricky Dale Harrington Jr.

Joshua Mahony, a non-profit executive and 2018 Democratic nominee for Congress in Arkansas's 3rd congressional district, filed to run for the Democratic nomination, but dropped out just after the filing deadline. No other Democrats filed within the filing deadline. Progressive activist Dan Whitfield ran as an independent, but suspended his campaign on October 1, 2020, after failing to qualify for the ballot.

U.S. senator before election Cory Gardner Republican Elected U.S. senator John Hickenlooper Democratic

One-term Republican Cory Gardner was elected in 2014 after serving four years in the United States House of Representatives, narrowly defeating one-term Democrat Mark Udall. Gardner sought a second term but lost to Democrat John Hickenlooper by 9.3 percentage points.

Hickenlooper is a popular former governor of Colorado, and led Gardner by as much as 20 percentage points in polls, with most pundits considering him a heavy favorite. Gardner was Colorado's only Republican statewide officeholder, and the once purple state has trended increasingly Democratic since his narrow win in 2014. Gardner also had low approval ratings due to his strong allegiance to Trump, who lost Colorado in 2016 to Hillary Clinton by 4.9%, and in 2020 to Joe Biden by 13.5%. Hickenlooper also raised significantly more money than Gardner.

One-term Democrat Chris Coons was re-elected in 2014; he first took office after winning a 2010 special election, which occurred after long-time senator Joe Biden resigned to become vice president of the United States (Biden also won the 2020 presidential election and became president). He faced an unsuccessful primary challenge from technology executive Jessica Scarane. Conservative activist Lauren Witzke and attorney Jim DeMartino ran for the Republican nomination.

The Delaware primary was held on September 15, 2020.

Georgia

Due to Republican senator Johnny Isakson's resignation from office for health reasons in 2019, both of Georgia's Senate seats were up for election in November 2020. The state had tilted Republican in Senate races since the mid-1990s, but increased support for Democrats in populous suburbs has made office elections more competitive; a close governor's race, multiple close U.S. House races, and many other close local office races resulted in Democratic gains in 2018 elections. Both the regular and special election were considered highly competitive toss-ups. Both of these elections received national attention, as if Republicans won at least one of these seats, they would maintain a Senate majority, but if the Democrats won both, the Senate would be split 50/50 with Vice President Kamala Harris breaking the tie.

One-term Republican David Perdue was elected in 2014, and sought a second term.

Jon Ossoff, a former congressional candidate, documentary film producer, and investigative journalist, defeated former Columbus mayor Teresa Tomlinson and 2018 lieutenant governor nominee Sarah Riggs Amico in the Democratic primary to secure nomination. He faced incumbent Republican David Perdue in the November 3 election.

In the November election, no candidate received 50% or more of the total vote; per Georgia law, the election advanced to a run-off between the top two finishers, Ossoff and Perdue, on January 5, 2021. Ossoff was projected the winner on January 6, and Perdue conceded on January 8.

U.S. senator before election Kelly Loeffler Republican Elected U.S. Senator Raphael Warnock Democratic

Three-term senator Johnny Isakson announced on August 28, 2019, that he would resign from the Senate on December 31, 2019, citing health concerns. Georgia governor Brian Kemp appointed Republican Kelly Loeffler to replace Isakson until a special election could be held; Loeffler took office on January 6, 2020, and competed in the November 2020 election to retain her seat.

Other Republicans who ran for the seat included Wayne Johnson, former chief operating officer of the Office of Federal Student Aid, and four-term U.S. representative Doug Collins.

A "jungle primary" was held November 3, 2020, but no candidate won more than 50% of the vote, so a run-off election between the top two finishers, Loeffler and Democratic challenger Raphael Warnock, was held on January 5, 2021. Warnock defeated Loeffler, who initially refused to concede and vowed to challenge the outcome, but conceded on January 7, after the storming of the U.S. Capitol.

Four-term democrat and Senate minority whip Dick Durbin, easily won a fifth term in office, defeating Republican Mark Curran by a 16-point margin.

Curran served as sheriff of Lake County from 2006 to 2018 and won the Republican primary with 41.55% of the vote.

Antiwar activist Marilyn Jordan Lawlor and state representative Anne Stava-Murray briefly challenged Durbin in the Democratic primary, but both ended up withdrawing.

2019 Chicago mayoral candidate Willie Wilson, a businessman and perennial candidate, ran as a member of the "Willie Wilson Party," with the backing of a handful of Chicago aldermen and the Chicago Police Union.

One-term republican Joni Ernst, first elected to the Senate in 2014, won a second term in office, defeating Democrat Theresa Greenfield.

Greenfield won the Democratic nomination, defeating former vice-admiral Michael T. Franken, attorney Kimberly Graham, and businessman Eddie Mauro in the primary.

Ernst's popularity had dropped in polls, and many considered this seat a possible Democratic pick-up, but Ernst was re-elected by a larger-than-expected 6.5 points.

Four-term Republican Pat Roberts, was re-elected in 2014 with 53.15% of the vote, and announced on January 4, 2019, that he would not be running for re-election in 2020.

In the Republican primary, United States representative Roger Marshall defeated former Kansas secretary of state Kris Kobach, state Turnpike Authority chairman Dave Lindstrom, state senate president Susan Wagle, and others.

There was considerable speculation about a Senate bid by Mike Pompeo (the United States secretary of state, former director of the Central Intelligence Agency, and former U.S. representative for Kansas's 4th congressional district), but he did not run.

Barbara Bollier, a state senator and former Republican, defeated former congressional candidate Robert Tillman for the Democratic nomination, but lost to Marshall with a more than expected 11.4 point margin.

U.S. senator before election Susan Collins Republican Elected U.S. senator Susan Collins Republican

Republican Susan Collins won a fifth term in office, defeating Speaker of the Maine House of Representatives Sara Gideon.

Gideon consistently led Collins in polls for almost the entire election cycle. Collins is considered one of the most moderate Republicans in the Senate and had never faced a competitive re-election campaign, even though Maine leans Democratic. But she faced growing unpopularity due to her increasingly conservative voting record, and her votes to confirm Brett Kavanaugh to the Supreme Court and to acquit Trump in his impeachment trial. Despite almost all polling and Gideon's formidable funding, Collins was re-elected by a surprising 8.6-point margin.

Educator and activist Lisa Savage also ran as a candidate for the Green party.

U.S. senator before election Ed Markey Democratic Elected U.S. senator Ed Markey Democratic

Democrat Ed Markey was re-elected in 2014, having won a 2013 special election to replace long-time incumbent John Kerry, who resigned to become U.S. secretary of state. He easily won a second full term in 2020, defeating Republican Kevin O'Connor by more than 33 percentage points.

Markey fended off a primary challenge from Joe Kennedy III, four-term U.S. representative for Massachusetts's Fourth District and grandson of former U.S. senator and U.S. attorney general Robert F. Kennedy. This marked the first time a member of the Kennedy family lost an election in Massachusetts.

O'Connor defeated Shiva Ayyadurai, a former independent senate candidate, in the Republican primary.

On August 24, 2020, perennial candidate Vermin Supreme launched a write-in campaign for the Libertarian nomination, but received too few votes to qualify for the general election ballot.
