Hawaii was admitted into the Union and elected one Democrat and one Republican to the Senate on July 28, 1959.

Two Democrats left the Senate after the election. Both seats were filled by Democrats.

In the special elections, the winners were seated during 1958 or before January 3, 1959. In the new state elections, the winners were seated with the new Congress on January 3, 1959. Ordered by election date.

In these regular elections, the winners were elected for the term beginning January 3, 1959; ordered by state.

All of the elections involved the Class 1 seats.

Maine was the tipping point state with a margin of 21.6%.

Alaska would become a new state January 3, 1959, and it elected two initial senators November 25, 1958, in advance of statehood. The Democratic Party thereby picked up 2 more seats.

In their next elections, Alaska's senators would be elected to 6-year terms.

Incumbent Republican William E. Jenner did not seek a second full term in office and was replaced by Democrat Vance Hartke, the mayor of Evansville. Hartke defeated incumbent Republican Governor of Indiana Harold W. Handley.

Jenner resigned shortly before the election and urged Handley, Jenner's political protégé, to seek his seat. A plan was proposed whereby Handley would resign the governorship, his lieutenant would appoint him senator, and he would finish the term and run as an incumbent. When the plan was revealed to the party leadership, they strongly advised him to not implement it because they feared it would hurt the party and be perceived as a scandal.^[8]

Handley did not resign from the governorship during his campaign and was widely criticized for the unprecedented action. Hartke accused Handley of raising taxes, breaking of his campaign promise, his reluctance in supporting right-to-work, and rising state unemployment. Statewide unemployment was just above 10% in April, but dropped to 6.9% by the end of September.^[8]

U.S. senator before election George W. Malone Republican Elected U.S. Senator Howard Cannon Democratic

In Nevada, incumbent Republican George W. Malone ran for re-election to a third term, but was defeated by Democrat Howard Cannon.

The campaign was considered^{[by whom?]} one of the most competitive and highly watched in the nation in 1958. Senator Malone was known nationally as a leader within the Republican Party's right wing and held key appointments on the Senate Finance and Interior Committees.^[18]

Malone campaigned on his experience and seniority in the Senate, using the slogan "He Knows Nevada Best." He received support from Eisenhower cabinet secretaries Fred Seaton and Ezra Taft Benson. Benson, one of the Twelve Apostles of the Church of Jesus Christ of Latter-Day Saints, was especially influential among Nevada's large Mormon population. His endorsement was seen as particularly important in light of Cannon's Mormon faith. Late in the campaign, Malone published full-page ads touting his effort to save Nevada from a federal gambling tax.^[18]

Cannon focused his attacks on Malone's absentee record in the Senate and his reputation on Capitol Hill as an unpopular extremist.^[18]

Cannon won the election by a safe margin owing to his overwhelming support in his native Clark County, which contained 47 percent of the state's registered voters. He was the first candidate from southern Nevada elected to the United States Senate.^[18]

Senator Malone was unopposed for re-nomination by the Republican Party.
