The 2014 United States Senate elections were held on November 4, 2014. A total of 36 seats in the 100-member U.S. Senate were contested. 33 Class 2 seats were contested for regular 6-year terms to be served from January 3, 2015, to January 3, 2021, and 3 Class 3 seats were contested in special elections due to Senate vacancies. The elections marked 100 years of direct elections of U.S. senators. Going into the elections, 21 of the contested seats were held by the Democratic Party, while 15 were held by the Republican Party.

The Republicans regained the majority of the Senate in the 114th Congress, which started in January 2015; the Republicans had not controlled the Senate since January 2007. They needed a net gain of at least 6 seats to obtain a majority and were projected by polls to do so. On election night, they held all of their seats and gained 9 Democratic-held seats. Republicans defeated 5 Democratic incumbents: Mark Begich of Alaska lost to Dan Sullivan, Mark Pryor of Arkansas lost to Tom Cotton, Mark Udall of Colorado lost to Cory Gardner, Mary Landrieu of Louisiana lost to Bill Cassidy, and Kay Hagan of North Carolina lost to Thom Tillis. Republicans also picked up another 4 open seats in Iowa, Montana, South Dakota, and West Virginia that were previously held by Democrats. Democrats did not pick up any Republican-held seats, but they did hold an open seat in Michigan.

This was the second consecutive election cycle held in a president's sixth year where control of the Senate changed hands, the first being in 2006. This was also the first time that the Democrats lost control of the Senate in a sixth-year midterm election cycle since 1918. With a total net gain of 9 seats, the Republicans made the largest Senate gain by any party since 1980. This is also the first election cycle since 1980 in which more than 2 incumbent Democratic senators were defeated by their Republican challengers. Days after the election cycle, the United States Election Project estimated that 36.4% of eligible voters voted, 4% lower than the 2010 elections, and possibly the lowest turnout rate since the 1942 election cycle.

As of 2022, this remains the last time that a Republican has won a U.S. Senate election in Colorado. This is the most recent Senate election where any Republican flipped an open Democratic-held seat. It also remains the last time that the president's party has suffered a net loss of Senate seats in a midterm election cycle.

Partisan composition

For a majority, Republicans needed at least 51 seats. Democrats could have retained a majority with 48 seats (assuming the two Independents continued to caucus with them) because the Democratic Vice President Joe Biden would become the tie-breaker. From 1915 to 2013, control of the U.S. Senate flipped in 10 of 50 cycles, or 20% of the time. Republicans had lost ground in the 2012 elections, leading to an internal fight among the Republican leadership over the best strategies and tactics for the 2014 Senate races. By December 2013, eight of the twelve incumbent Republicans running for re-election saw Tea Party challenges. However, Republican incumbents won every primary challenge. Although Democrats saw some opportunities for pickups, the combination of Democratic retirements and numerous Democratic seats up for election in swing states and red states gave Republicans hopes of taking control of the Senate. 7 of the 21 states with Democratic seats up for election in 2014 had voted for Republican Mitt Romney in the 2012 presidential election compared to just 1 state with a Republican senator that voted for Barack Obama. Democrats also faced the lower voter turnout that accompanies mid-term elections.

Poll aggregation website FiveThirtyEight gave the Republican Party a 60% chance of taking control of the Senate as of September 28. Another poll aggregation website, RealClearPolitics, gave the Republican Party a net gain of 7 seats. Due to the closeness of several races, it was initially believed that Senate control might not be decided on election night. Both Louisiana and Georgia were seen as competitive, and both states require a run-off election if no candidate takes a majority of the vote.

Two independent candidates (in Kansas and South Dakota) refused to commit to caucusing with either party. In the final months of the race, polls showed them with viable chances of winning, leading some analysts to speculate on the possibility of an "Independent caucus" that could also include Maine Senator Angus King and possibly Vermont Senator Bernie Sanders. However, no Independent won a Senate race in 2014, and King and Sanders continue to caucus with the Democratic Party following the 2014 election cycle.

By midnight ET, most major networks projected that the Republicans would take control of the Senate. The party held all three competitive Republican-held seats (Kentucky, Kansas, and Georgia), and defeated incumbent Democrats in North Carolina, Colorado, and Arkansas. Combined with the pick-ups of open seats in Iowa, Montana, South Dakota, and West Virginia, the Republicans made a net gain of 7 seats before the end of the night. Republicans defeated three incumbent Democrats, a task the party had not accomplished since the 1980 election cycle. Five of the seven confirmed pickups were in states that voted for Mitt Romney in 2012, but two of the seats that Republicans won represent states that voted for Barack Obama in 2012 (Colorado and Iowa). Of the three races that were not called by the end of election night, Alaska and Virginia were still too close to call, while Louisiana held a December 6 run-off election. Virginia declared Democrat Mark Warner the winner of his race by a narrow margin over Republican Ed Gillespie on November 7, and Alaska declared Dan Sullivan the winner against Democratic incumbent Mark Begich a week later, on November 12. Republican Bill Cassidy defeated Democratic incumbent Mary Landrieu in the Louisiana runoff on December 6.

Election spending

Altogether, at least $3.67 billion was spent by candidates, parties, committees and outside groups in the 2014 election cycle. Spending on the 2014 Senate elections by outside groups (i.e., organizations other than a candidate's campaign, such as super PACs and "dark money" nonprofit groups) more than doubled from 2010. In the 10 competitive races for which data was available, outside groups accounted for 47% of spending, candidates accounted for 41% of spending, and parties accounted for 12% of spending. The Senate race with the most outside spending was in North Carolina, at $80 million, a new record.

The top outside spenders in the 11 most competitive Senate races were the following:

• On the Republican side, the National Republican Senatorial Committee, Crossroads GPS, U.S. Chamber of Commerce, Ending Spending Action Fund, Freedom Partners Action Fund, American Crossroads, and the NRA Political Victory Fund.
• On the Democratic side, the Democratic Senatorial Campaign Committee, Senate Majority PAC, and NextGen Climate Action Committee.

Results summary

The Republican Party made a net gain of nine U.S. Senate seats in the 2014 elections.

Going into the elections, there were 53 Democratic, 45 Republican and 2 independent senators (both of whom caucus with the Democrats). In all, there were 36 elections: 33 senators were up for election this year as class 2 senators, and 3 faced special elections (all from Class 3). Of all these seats, 21 were held by Democrats and 15 were held by Republicans.

Consensus predictions for the races:
     Safe Democratic seat      Competitive Democratic-held seat
     Safe Republican seat      Competitive Republican-held seat

Predicted probability of Republican takeover

Several websites used poll aggregation and psephology to estimate the probability that the Republican Party would gain enough seats to take control of the Senate.

Source	Probability of Republican control	Updated
FiveThirtyEight	76.2%	Nov 4
Princeton Election Consortium (Sam Wang)	65%	Nov 3
Huffington Post	79%	Nov 3
The Upshot (The New York Times)	70%	Nov 3
The Washington Post	97%	Nov 3
Daily Kos	90%	Nov 4

Predictions

Republicans needed to win at least six in order to gain a majority of 51 seats and Democrats needed to win at least seven in order to hold a majority of 50 seats (including the two independents who currently caucus with the Democrats) and the tie-breaking vote of Vice President Joe Biden.

Two-term incumbent Republican Saxby Chambliss had been re-elected with 57% of the vote in 2008 in a runoff election with former state Representative Jim Martin; Georgia requires run-off elections when no Senate candidate wins over 50% of the vote. Chambliss did not seek a third term.

Political activist Derrick Grayson, Representatives Jack Kingston of Georgia's 1st congressional district, Paul Broun of Georgia's 10th congressional district, and Phil Gingrey of Georgia's 11th congressional district all declared their candidacy for the Republican nomination, as did former secretary of state Karen Handel. In the May 20 primary, no candidate received a majority of votes, so the top two candidates faced each other in a runoff; Perdue narrowly won against Kingston in the runoff primary election on July 22 with 50.9% of the vote.

Michelle Nunn, CEO of Points of Light and the daughter of former U.S. Senator Sam Nunn, won the Democratic nomination. Other declared Democratic candidates included former state senator Steen Miles, psychiatrist Branko Radulovacki, and former US Army Ranger Todd Robinson. Amanda Swafford, a former Flowery Branch, Georgia, city councilwoman, received the Libertarian Party of Georgia nomination.

Daniel Inouye, the second longest serving United States Senator in U.S. history, died on December 17, 2012, after respiratory complications. Hawaii law allows the Governor of Hawaii, to appoint an interim Senator "who serves until the next regularly-scheduled general election, chosen from a list of three prospective appointees that the prior incumbent's political party submits". Governor Neil Abercrombie did so, selecting Lieutenant Governor Brian Schatz to fill the Senate seat. Inouye had been re-elected in 2010 with 72% of the vote. Schatz was challenged in the Democratic primary by Congresswoman Colleen Hanabusa of Hawaii's 1st congressional district, who Inouye had hoped would be his successor. Schatz defeated Hanabusa in the primary with 48.5% to 47.8%.

Campbell Cavasso, former state representative and nominee for the U.S. Senate in 2004 and 2010, was the Republican nominee.

Kentucky Secretary of State Alison Lundergan Grimes, with support from much of Kentucky's Democratic leadership, won the Democratic primary. Actress Ashley Judd publicly claimed to be considering a run for the Democratic nomination, but ultimately decided against it.

Ed Marksberry pursued an independent bid after dropping out of the Democratic field in September 2013.

Three-term incumbent Democrat Mary Landrieu had been re-elected with 52% of the vote in 2008. Landrieu ran for a fourth term.

Louisiana uses a unique jungle primary system that eschews primaries in favor of run-off elections between the top two candidates; this run-off can be avoided if the winning candidate receives over 50% of the vote. Democrats Wayne Ables, Vallian Senegal, and William Waymire ran against Landrieu in the election, as did Republicans Bill Cassidy (representative of Louisiana's 6th congressional district), Thomas Clements (small business owner), and retired Air Force Colonel Rob Maness. Electrical Engineer Brannon McMorris ran as a Libertarian.

Because Republican candidate Maness took almost 14% of the votes in the primary, there was a runoff election on December 6, 2014, between Landrieu (42%) and Cassidy (41%). Cassidy won the runoff with 56% of the vote.

Six-term incumbent Republican Thad Cochran, re-elected with 62% of the vote in 2008, ran for re-election. Cochran was the last incumbent senator to declare his plans, leading to widespread speculation that he might announce his retirement. Tea Party candidate Chris McDaniel, a conservative Mississippi state senator, ran against Cochran in the Republican primary. Neither McDaniel nor Cochran was able to get 50% of the vote in the first round of the primary, so a runoff election was held June 24. Cochran won the runoff election by 51% to 49%, with the help of Democratic voters eligible to vote in the state's open primaries who chose Cochran as their preferred Republican. McDaniel filed a lawsuit to challenge the results of the run-off, but the challenge was rejected on appeal by the Supreme Court of Mississippi.

Former Congressman Travis Childers was the Democratic nominee.

Six-term incumbent Democrat Max Baucus, the longest-serving senator in Montana's history, had been re-elected with 73% of the vote in 2008. Baucus announced on April 23, 2013, that he would retire in 2014, rather than seek re-election to a seventh term. Baucus was appointed as the United States Ambassador to China, leading him to resign from the Senate in February 2014.

Following Baucus's confirmation as ambassador, Governor Steve Bullock appointed the Lieutenant Governor John Walsh to fill the vacant senate seat. Former lieutenant governor John Bohlinger was defeated by Walsh in the Democratic primary. Amid controversy over alleged plagiarism in a 2007 research paper, Walsh pulled out of the race. The Montana Democratic Party held a special nominating convention on August 16 to choose a replacement for Walsh. First-term state representative Amanda Curtis won the nomination, thereby becoming the new Democratic nominee.

Congressman Steve Daines won the Republican nomination over state Representative Champ Edmunds of Missoula and David Leaser of Kalispell.
