1908 United States presidential election in Oklahoma

The 1908 United States presidential election in Oklahoma took place on November 3, 1908. All 46 states were part of the 1908 United States presidential election. Voters chose seven electors to the Electoral College, who voted for president and vice president. This was the first presidential election Oklahoma participated in, as it had become the 46th state on November 16, 1907.

Oklahoma was won by the Democratic nominees, former U.S. Representative William Jennings Bryan and his running mate John W. Kern of Indiana. They defeated the Republican nominees, Secretary of War William Howard Taft of Ohio and his running mate James S. Sherman of New York. Bryan won the state by a narrow margin of 4.66%, establishing Oklahoma as a Democratic-leaning state, a position it would hold for several decades.

Prior to 1952, it consistently voted Democratic in presidential elections outside of the Republican landslides in 1920 and 1928. Only Lyndon B. Johnson in his 1964 landslide has carried the state for Democrats since 1952. This is one of two times that the state voted for a losing Democrat, along with 1924. This was one of only two elections in which Oklahoma County, home to Oklahoma City, voted for a candidate that lost the state, along with 1920.

Eugene V. Debs, the Socialist candidate, won 8.52% of the vote, demonstrating the strength of the Socialist movement in Oklahoma at this point in the state's history. Debs would go on to improve this performance in 1912, winning around twice as much of the percentage of the vote in Oklahoma.
