The 1914 United States Senate election in Oklahoma took place on November 3, 1914. Incumbent Senator Thomas Gore, a Democrat, sought re-election in his first popular election. He was challenged by Republican nominee John H. Burford, a former Justice on the Territorial Oklahoma Supreme Court; Socialist nominee Patrick S. Nargle, a former U.S. Marshal; and Progressive nominee William O. Cromwell, the former State Attorney General. Despite the fact that the left-leaning vote was split several ways in the election, Gore won re-election in a landslide, receiving 48% of the vote to Burford's 29, Nagle's 21%, and Cromwell's 2%.

Thomas Pryor Gore was an American politician who served as one of the first two United States senators from Oklahoma, from 1907 to 1921 and again from 1931 to 1937. He first entered politics as an activist for the Populist Party, and continued this affiliation after he moved to Texas. In 1899, just before moving to Oklahoma Territory to practice law in Lawton, he formally joined the Democratic Party and campaigned for William Jennings Bryan. In the Senate, his anti-war beliefs caused him conflict with Democratic presidents Woodrow Wilson and Franklin D. Roosevelt.
