The 1968 United States Senate elections were elections for the United States Senate. Held on November 5, the 34 seats of Class 3 were contested in regular elections. They coincided with the presidential election of the same year. The Republicans picked up five net seats in the Senate. This saw Republicans win a Senate seat in Florida for the first time since Reconstruction.
Republicans would gain another seat after the election when Alaska Republican Ted Stevens was appointed to replace Democrat Bob Bartlett, reducing Democrats' majority to 57–43.
This is the earliest round of Senate elections in which a first-elected member is still alive (Bob Packwood, R-OR).

After electing Republicans post-Reconstruction, Alabama had historically voted Democratic in local, state, and presidential elections from the 1870s until the 1960s with the passage of the Civil Rights Act. However, in 1948 Alabama did not support the Democratic ticket for the first time in nearly 100 years, voting for Strom Thurmond, who ran a third-party campaign. Democrats lost ground due to the unpopularity of the Civil Rights Act among white voters, who at the time comprised nearly the entire electorate. In 1964, Barry Goldwater became the first Republican to win the state of Alabama since Ulysses Grant, while the state elected Republicans to its congressional delegation for the first time since the turn of the century. Goldwater voted against the Civil Rights Act, which boosted his popularity in Southern states.
In 1962, J. Lister Hill ran for re-election to this seat to a fifth term but faced an unusually close race against Republican James D. Martin, who came within 1% of unseating the incumbent. In 1968, Republicans looked to build upon their momentum but faced a challenge when Lieutenant Governor James B. Allen, a staunch conservative, was nominated by the Democratic Party. Republicans also failed to capitalize on the candidacy of liberal Democrat Hubert H. Humphrey due to the third-party candidacy of Governor George Wallace limiting Republican support. Allen defeated Republican Perry Hooper by a wide margin in the general election and faced little opposition in 1978.

Democrat Ernest Gruening had served as one of the state's inaugural senators alongside Democrat Bob Bartlett since 1959. He was re-elected in a landslide victory in 1962. In 1968, he was challenged by former Speaker of the Alaska House of Representatives, Mike Gravel, who ran on a campaign of youth. [3] Gravel upset Gruening in the Democratic primary with just under 53% of the vote to 47% for Gruening.
Gravel faced former Anchorage Mayor Republican Elmer E. Rasmuson in the general election, while Gruening ran a write-in campaign. Gravel won a three-way race with 45% of the vote to 37% for Rasmuson, with incumbent Gruening scoring 17%.

Elson was defeated by a wide margin, however, by former U.S. senator and Republican presidential nominee Barry Goldwater. Prior to Goldwater's election, the seat had been held for decades by the Democratic Party under Carl Hayden, and would remain under Republican Party control until 2020. Elson had previously challenged U.S. senator Paul Fannin in 1964, when Goldwater vacated his seat to run for President against Lyndon B. Johnson.

J. William Fulbright was first elected in 1944 against token Republican opposition. He ran unopposed in 1950 and won by large margins in 1956 and 1962, but he saw his vote percentage slip in the latter. In the wake of Civil Rights legislation, which many southern whites opposed, Fulbright was re-elected in 1968 but by the smallest margin of his career. He faced Charles T. Bernard and won with just over 59% of the vote. Arkansas would not elect a Republican to this seat until 2010 with John Boozman's election.

California was generally considered to be a Republican stronghold throughout the early 1900s. Until 1959, Republicans controlled most government offices as well as both houses of state government. However, Pat Brown was elected governor in 1958 and ushered in a wave of Democratic success.
Along with California Secretary of State Frank M. Jordan, incumbent U.S. Senator Thomas Kuchel was one of the last Republicans elected from California at the state or U.S. Senate level. Kuchel had been re-elected by a wide margin in 1962, winning every county in the state, and was the Minority Whip for the Republican Party.
However, in 1968 he faced a primary challenge from California Superintendent of Public Instruction Max Rafferty, who ran to the right of moderate Kuchel. In an upset, Rafferty defeated Kuchel in the primary, 50-47%.
In the Democratic primary, former California State Controller Alan Cranston won the primary with 58% of the vote.
Despite Richard Nixon's concurrent win in the presidential election (as well as in the state of California), Cranston defeated Rafferty on election day with just under 52% of the vote, flipping the state's other senate seat to the Democrats. Rafferty took just under 47% of the vote. Cranston would serve until 1993 in the senate.

Incumbent Democrat George Smathers retired. After supporting Republicans during Reconstruction, Florida supported almost only Democrats down-ballot until the 1940s, when the state voted for Eisenhower. Claude R. Kirk Jr. was elected governor in 1966 as Republicans gained ground in the South due to Democrats shifting leftward and Republicans rightward.
Popular Democrat LeRoy Collins defeated State Attorney General Earl Faircloth in the Democratic primary, while Republican Representative Edward Gurney won the Republican primary. Despite less name recognition in the state, Gurney defeated Collins by 11 points and won all but five counties.

Incumbent Democrat Birch Bayh was elected in 1962, defeating incumbent Republican Homer E. Capehart by around 11,000 votes. In 1970, he ran for re-election and faced Republican State Representative William Ruckelshaus in the general election.
Ruckelshaus ran a close race but Bayh was ultimately re-elected by a two-point margin. This would actually be Bayh's largest vote percentage in an election to the U.S. Senate. In 1974, he won a narrow majority of the vote over Republican Richard Lugar though he did increase his margin of victory. He was defeated in his re-election bid in 1980 by future Vice President Dan Quayle.
Birch Bayh's son Evan Bayh would also serve in the U.S. Senate from 1999 to 2011.

Incumbent Democrat Daniel Brewster was originally elected in 1962 over Republican Representative Edward Tylor Miller. He won the Democratic primary and faced Republican Representative Charles Mathias in the general election. However, Democrat George P. Mahoney ran in the election under the American Independent Party. Mahoney, who ran against the Civil Rights movement, had previously been the Democratic nominee for governor in 1966 losing to Spiro Agnew. Hyman A. Pressman ran an independent campaign which allowed Republican Agnew to carry the heavily Democratic state with 49.5% of the vote.
Similarly, Mahoney ran a well-funded campaign in 1968 and Brewster was defeated in the general election. Mathias won just 48% of the vote to 39% for Brewster (and 13% for Mahoney), similarly elected to Agnew. Mathias would nonetheless have no trouble being re-elected in 1974 and 1980 (when he won the city of Baltimore). Mathias is the last Republican to represent Maryland in the U.S. Senate.

Incumbent Democrat Fritz Hollings easily defeated Republican state senator Marshall Parker in a rematch of the election two years earlier, to win his second (his first full) term.
Hollings faced no opposition from South Carolina Democrats, and avoided a primary election. Marshall Parker, the state senator from Oconee County in the Upstate, was persuaded by South Carolina Republicans to enter the race, and he did not face a primary challenge.
After a close election loss to Fritz Hollings in 1966, the Republicans felt that Parker might have a chance at defeating Hollings by riding Nixon's coattails in the general election. However, the Republicans did not provide Parker with the financial resources to compete, and he subsequently lost by a bigger margin to Hollings than two years prior.

Hoff ran a write-in campaign in the Democratic primary for this seat but lost to Republican Aiken by a wide margin. Aiken thus ran with both nominations and secured a victory. This would be once staunchly-Republican Vermont's last time to support a Republican for this seat. In 1974, Patrick Leahy would win and become the first Democratic Senator from Vermont.

The 1998 United States Senate elections were held on November 3, 1998, with the 34 seats of Class 3 contested in regular elections. This was seen as an even contest between the Republican Party and Democratic Party. While the Democrats had to defend more seats up for election, Republican attacks on the morality of President Bill Clinton failed to connect with voters and anticipated Republican gains did not materialize. The Republicans picked open seats up in Ohio and Kentucky and narrowly defeated Democratic incumbent Carol Moseley Braun, but these were cancelled out by the Democrats' gain of an open seat in Indiana and defeats of Republican Senators Al D'Amato and Lauch Faircloth. The balance of the Senate remained unchanged at 55–45 in favor of the Republicans.
The 1996 United States Senate elections were held on November 5, 1996, with the 33 seats of Class 2 contested in regular elections. Special elections were also held to fill vacancies. They coincided with the presidential election of the same year, in which Democrat Bill Clinton was re-elected president.
The 1990 United States Senate elections were held on Tuesday, November 6, 1990, with the 33 seats of Class 2 contested in regular elections. Special elections were also held to fill vacancies. The Democratic Party increased its majority with a net gain of one seat from the Republican Party. The election cycle took place in the middle of President George H. W. Bush's term, and as with most other midterm elections, the party not holding the presidency gained seats in Congress. This was the first time since 1980 that any party successfully defended all their own seats, and the first time Democrats did so since 1958.
The 1988 United States Senate elections were elections for the United States Senate. Held on November 8, 1988, the 33 seats of Class 1 were contested in regular elections.
