The 1912 United States Senate election in Kentucky was held on January 16, 1912, after an initial election on January 9, 1912. Democratic representative Ollie Murray James was elected by the Kentucky General Assembly to the United States Senate. The election was held twice due to ambiguity in the law setting the election date. This was the last senate election in Kentucky before the ratification of the Seventeenth Amendment, which mandated the election of senators by popular vote.
The Democratic Party chose to select its candidate by a primary election, which was not required by law. The election was held Saturday, July 1, 1911. The only candidates to submit their names for the election were James and incumbent senator Thomas H. Paynter. However, Paynter withdrew his candidacy before the election was held, leaving James without opposition.
The Republican Party chose to select its candidate by legislative caucus, with Edwin P. Morrow winning the nomination unanimously on Monday, January 1, 1912.
