The lieutenant governor of Kentucky was created under the state's second constitution, which was ratified in 1799. The inaugural officeholder was Alexander Scott Bullitt, who took office in 1800 following his election to serve under James Garrard in 1799. The lieutenant governor becomes governor of Kentucky under circumstances similar to those under which the vice president of the United States assumes the presidency. The current lieutenant governor is Democrat Jacqueline Coleman, who has been office since December 10, 2019.

James Garrard was an American farmer, Baptist minister and politician who served as the second governor of Kentucky from 1796 to 1804. Because of term limits imposed by the state constitution adopted in 1799, he was the last Kentucky governor elected to two consecutive terms until the restriction was eased by a 1992 amendment, allowing Paul E. Patton's re-election in 1999.
