Thomas Metcalfe, also known as Thomas Metcalf or as "Stonehammer", was a U.S. Representative, Senator, and the tenth Governor of Kentucky. He was the first gubernatorial candidate in the state's history to be chosen by a nominating convention rather than a caucus. He was also the first governor of Kentucky who was not a member of the Democratic-Republican Party.

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.
