Ruby Laffoon was an American attorney and politician who served as the 43rd Governor of Kentucky from 1931 to 1935. A Kentucky native, at age 17, Laffoon moved to Washington, D.C., to live with his uncle, U.S. Representative Polk Laffoon. He developed an interest in politics and returned to Kentucky, where he compiled a mixed record of victories and defeats in elections at the county and state levels. In 1931, he was chosen as the Democratic gubernatorial nominee by a nominating convention, not a primary, making him the only Kentucky gubernatorial candidate to be chosen by a convention after 1903. In the general election, he defeated Republican William B. Harrison by what was then the largest margin of victory in Kentucky gubernatorial history.

The governor of the Commonwealth of Kentucky is the head of government in Kentucky. Sixty-two men and one woman have served as governor of Kentucky. The governor's term is four years in length; since 1992, incumbents have been able to seek re-election once before becoming ineligible for four years. Throughout the state's history, four men have served two non-consecutive terms as governor, and four others have served two consecutive terms, the most recent being current governor Andy Beshear, who was re-elected to a second term on November 7, 2023. Kentucky is one of only five U.S. states that hold gubernatorial elections in odd-numbered years.
