William Henry McMaster was an American politician who served as the tenth Governor of South Dakota from 1921 until 1925. A member of the Republican Party, he went on to serve as a member of the United States Senate from South Dakota from 1925 to 1931.
The 1894 South Dakota gubernatorial election was held on November 6, 1894. Incumbent Republican Governor Charles H. Sheldon ran for re-election to a second term. Despite facing a thread of defeat at the Republican convention, Sheldon was renominated unanimously. In the general election, he faced Populist nominee Isaac Howe, a Spink County Judge; James A. Ward, the former state chairman of the South Dakota Democratic Party; and Prohibition nominee M. D. Alexander. The election was largely a replay of the gubernatorial elections of 1890 and 1892, with the Farmers' Alliance candidate placing second and the Democratic nominee placing a distant third. This time, however, Sheldon won an outright majority and the Democratic Party's vote share shrunk to just 11%, its worst performance in state history.
The 1892 South Dakota gubernatorial election was held on November 8, 1892. Incumbent Republican Governor Arthur C. Mellette declined to seek re-election to a third term. Former territorial legislator Charles H. Sheldon was nominated by the Republican Party as Mellette's replacement, and he faced former legislator Abraham Lincoln Van Osdel, a leader in the South Dakota Farmers' Alliance and the nominee of the Independent Party, along with Democratic nominee Peter Couchman, in the general election. The result was largely a replay of the 1890 election, with Sheldon winning by a large margin, but only a plurality, and Van Osdel taking second place over Couchman.
The 1896 South Dakota gubernatorial election was held on November 3, 1896. Incumbent Republican Governor Charles H. Sheldon declined to run for re-election to a third term. Former Secretary of State Amund O. Ringsrud was nominated as Sheldon's replacement at the Republican convention. Ringrud's main opponent was businessman Andrew E. Lee, who was nominated by a makeshift coalition of Populists, Free Silver Republicans, and Democrats. In the general election, Lee narrowly defeated Ringsrud, the first defeat for the Republican Party in a gubernatorial election since statehood.
The 1904 South Dakota gubernatorial election was held on November 8, 1904. Incumbent Republican Governor Charles N. Herreid declined to run for re-election to a third term. Clark County State's Attorney Samuel H. Elrod won the Republican nomination to run as Herreid's successor, and he faced Democratic nominee Louis N. Crill, the former president of the state Senate, and former U.S. Congressman Freeman Knowles, the Socialist nominee. For the first time since 1894, the Democratic and Populist Parties nominated separate candidates. Ultimately, the split in the two parties did not prove dispositive; Elrod defeated Crill and the other candidates in a landslide.
The 1918 United States Senate election in South Dakota took place on November 5, 1918. Incumbent Republican Senator Thomas Sterling sought re-election in his first popular election. He defeated former Governor Frank M. Byrne in the Republican primary and then faced former State Representative Orville Rinehart, the 1916 Democratic nominee for Governor, in the general election. Sterling defeated Rinehart, along with independent candidate W. T. Rafferty, by a wide margin to win re-election.
The 1962 United States Senate election in South Dakota took place on November 6, 1962. Incumbent Republican Senator Francis H. Case ran for re-election to a third term. He won the Republican primary against Attorney General A. C. Miller, but shortly after the primary, died. The Republican State Central Committee named Lieutenant Governor Joseph H. Bottum as Case's replacement on the ballot, and Governor Archie Gubbrud appointed Bottum to fill the vacancy caused by Case's death. In the general election, Bottum was opposed by Democratic nominee George McGovern, the Director of Food for Peace and the former U.S. Congressman from South Dakota's 1st congressional district. The contest between Bottum and McGovern was quite close, with McGovern narrowly defeating him for election by just 597 votes, making him the first Democrat to win a Senate election in South Dakota since William J. Bulow's win in 1936.
The 1970 South Dakota gubernatorial election was held on November 3, 1970. Primary elections were held on June 2, 1970. Incumbent Republican Governor Frank Farrar was defeated by Democratic nominee Richard F. Kneip who won 54.85% of the vote.

The 1912 South Dakota gubernatorial election was held on November 5, 1912. Incumbent Republican Governor Robert S. Vessey declined to run for re-election to a third term. Lieutenant Governor Frank M. Byrne won the Republican primary to succeed Vessey, and then faced State Senator Edwin S. Johnson, the Democratic nominee, in the general election. Byrne only narrowly defeated Johnson, winning just 49% of the vote to Johnson's 46%, the closest gubernatorial election since 1898.
The 1952 South Dakota gubernatorial election was held on November 4, 1952.
The 1946 South Dakota gubernatorial election was held on November 5, 1946. Incumbent Republican Governor Merrell Q. Sharpe ran for re-election to a third term, but was defeated in the Republican primary by Attorney General George T. Mickelson. In the general election, Mickelson faced farmer Richard Haeder, the Democratic nominee. In part because of South Dakota's growing trend toward the Republican Party, and because of the national Republican landslide, Mickelson easily defeated Haeder, winning 67% of the vote to Haeder's 33%.
The 1916 South Dakota gubernatorial election was held on November 7, 1916. Incumbent Republican Governor Frank M. Byrne declined to seek re-election to a third term. Lieutenant Governor Peter Norbeck won the Republican primary to succeed him, and in the general election faced State Representative Orville V. Rinehart. Norbeck won his first term as Governor in a landslide over Rinehart.
The 1920 South Dakota gubernatorial election was held on November 2, 1920. Incumbent Republican Governor Peter Norbeck declined to run for re-election, instead choosing to run for the U.S. Senate. Lieutenant Governor William H. McMaster won the Republican primary and advanced to the general election, where he faced Nonpartisan League candidate Mark P. Bates and former State Senator William W. Howes, the Democratic nominee. The election was largely a replay of the 1918 election, with McMaster winning a large victory, Bates coming in second, and Howes coming in a distant third.
The 1924 South Dakota gubernatorial election was held on November 4, 1924. Incumbent Republican Governor William H. McMaster declined to run for re-election to a third term, instead opting to run for the U.S. Senate. Lieutenant Governor Carl Gunderson won the Republican primary unopposed. In the general election, he faced three prominent opponents: Democratic nominee William J. Bulow, a former State Senator and Mayor of Beresford; Farmer–Labor nominee A. L. Putnam; and perennial candidate Richard O. Richards. Gunderson. With the left-leaning vote split, Gunderson won the election in a landslide.
The 1926 South Dakota gubernatorial election was held on November 2, 1926. Incumbent Republican Governor Carl Gunderson ran for re-election to a second term. The election was largely a rematch of the 1924 election, with Gunderson's chief opponent from two years prior, Democrat William J. Bulow, challenging him once again. Two other candidates—Farmer–Labor nominee Tom Ayres and Pierre Mayor John E. Hipple, an independent—also ran. Though the left-leaning vote was split, Bulow was still able to win a decisive victory over Gunderson, whose support from two years earlier had completely collapsed.
The 1928 South Dakota gubernatorial election was held on November 6, 1928. Incumbent Democratic Governor William J. Bulow ran for re-election to a second term. In the general election, he faced Attorney General Buell F. Jones, the Republican nominee. Despite Republican presidential nominee Herbert Hoover overwhelmingly defeating Democratic nominee Al Smith overwhelmingly in South Dakota, Bulow defeated Jones by a decisive margin to retain the governorship. In so doing, he became the first Democratic candidate for Governor to receive a majority of the vote in the state's history.
The 1934 South Dakota gubernatorial election was held on November 6, 1934. Incumbent Democratic Governor Tom Berry ran for re-election to a second term. After defeating an intra-party challenge from Lieutenant Governor Hans Ustrud, Berry faced magazine publisher William C. Allen, who won a crowded Republican primary with a large plurality. Aided by the national environment favoring Democrats, Berry won re-election in a landslide.
