The 1964 United States Senate elections were held on November 3. The 33 seats of Class 1 were contested in regular elections. Special elections were also held to fill vacancies. They coincided with the election of President Lyndon B. Johnson by an overwhelming majority, to a full term. His Democratic Party picked up a net two seats from the Republicans. {{As of|2023}}, this was the last time either party has had a two-thirds majority in the Senate, which allowed the Senate Democrats to override a veto, propose constitutional amendments, or convict and expel certain officials without any votes from Senate Republicans. However, internal divisions would have prevented the Democrats from having done so. The Senate election cycle coincided with Democratic gains in the House in the same year.

In a close race in Nevada, Democratic incumbent Howard Cannon won re-election over Republican Lieutenant Governor Paul Laxalt by fewer than 100 votes. Laxalt joined Cannon in the Senate when he won Nevada's other seat in 1974. Patrick V. McNamara (D–Michigan) later died on April 30, 1966, and was replaced on May 11, 1966, by appointee Robert P. Griffin (R), reducing Democrats' majority to 67–33.

Notably, of the 35 seats up for election this year, 26 were held by Democrats, who managed to retain 25 of them. A party defending two-thirds of the seats up for election would not make net gains in the Senate again until 2012. Coincidentally, it would be the same Senate class, class 1.

Incumbent Barry Goldwater decided not to run for re-election to a third term, instead running for President of the United States as the Republican Party nominee against Lyndon B. Johnson.{{Cite book |last1=Dean |first1=John W.|first2=Barry M. |last2= Goldwater Jr. |url=https://archive.org/details/puregoldwater00gold |title=Pure Goldwater |publisher=Palgrave Macmillan |year=2008 |isbn=978-0230611337 |edition=1st |location=New York, N.Y. |page=[https://archive.org/details/puregoldwater00gold/page/72 72] |quote= |url-access=registration}} Governor of Arizona Paul Fannin ran unopposed in the Republican primary, and defeated Democratic nominee Roy Elson, who was a staff member for U.S. senator Carl Hayden until Hayden's retirement in 1969. Despite a landslide loss throughout the country, and Goldwater only able to obtain 50.45% of the vote in his home state of Arizona, Fannin managed to prevail in the state's Senate election. Goldwater would win the election for the other Senate seat in 1968 when Hayden retired from the post and serving two more terms.

Incumbent Democrat Mike Mansfield, who was first elected to the Senate in 1952 and was re-elected in 1958, ran for re-election. Mansfield won the Democratic primary in a landslide, and advanced to the general election, where he faced Alex Blewett, the Majority Leader of the Montana House of Representatives and the Republican nominee. Though Mansfield's margin was significantly reduced from 1958, he still overwhelmingly defeated Blewett and won his third term in the Senate.

John English, a Nassau County leader who helped John F. Kennedy during the 1960 presidential election, encouraged Robert Kennedy to oppose Keating. At the time, Samuel S. Stratton, a member of the United States House of Representatives from New York's 35th congressional district, was considered the most likely Democratic candidate. At first, Kennedy resisted. After President Kennedy's assassination, Robert Kennedy remained as Attorney General for Lyndon B. Johnson. However, Johnson and Kennedy feuded. Kennedy decided to run for the Senate in New York in August, and resigned from the Cabinet on September 3, 1964. While many reform Democrats resisted Kennedy, support from Robert F. Wagner Jr., and party bosses like Charles A. Buckley, of The Bronx, and Peter J. Crotty,{{efn|Peter J.

During the campaign, Kennedy was frequently met by large crowds. Keating accused Kennedy of being a carpetbagger from Massachusetts. Kennedy responded to these charges in a televised town meeting by saying, "If the senator of the state of New York is going be selected on who's lived here the longest, then I think people are going vote for my opponent. If it's going be selected on who's got the best New York accent, then I think I'm probably out too. But I think if it's going be selected on the basis of who can make the best United States senator, I think I'm still in the contest."{{Cite web |title=Lessons for Mrs. Clinton from 1964 - June 15, 1999 |url=http://www.cnn.com/ALLPOLITICS/stories/1999/06/15/senate.2000/hillary.carpetbaggers/ |access-date=March 19, 2018 |website=CNN}}

The Democratic/Liberal candidate was elected. Campaign help from President Lyndon B. Johnson, as well as the Democratic landslide after the assassination of John F. Kennedy, helped carry Kennedy into office, as Kennedy polled about 1.1 million votes less in New York than Johnson did. The incumbent Keating was defeated.

Incumbent Democratic-NPL Senator Quentin Burdick sought and received re-election to his second term, defeating Republican candidate Thomas S. Kleppe, who later became the United States Secretary of the Interior.

Only Burdick filed as a Democratic-NPLer, and the endorsed Republican candidate was Thomas S. Kleppe, who would go on to serve two terms as a Representative for North Dakota's second congressional district from 1967 to 1971. Burdick and Kleppe won the primary elections for their respective parties.

This election was to determine who would serve for the final two years of the term to which Robert S. Kerr had been elected in 1960. Kerr had died in January 1963, and outgoing Governor J. Howard Edmondson was appointed to take his place. Edmondson hoped to win the special election, but lost the Democratic primary to former state senator Fred R.

Incumbent Democrat Ralph Yarborough defeated future President of the United States George H. W. Bush.

Although Yarborough won this election, he would lose the Democratic Primary six years later, in 1970, to Lloyd Bentsen. Bush later went on to win an election for the United States House of Representatives in 1966; he was elected vice president of the United States in 1980 and was elected president in 1988.
