The 1848 Kentucky gubernatorial election was held on August 7, 1848, to elect the governor of Kentucky. The election was characterized by a contest between the Whig Party and the Democratic Party during a period of high national political tension leading up to the 1848 presidential election.
The Whig Party nominated John J. Crittenden, a prominent national figure who had served multiple terms in the United States Senate and as U.S. Attorney General under William Henry Harrison. Crittenden resigned his seat in the Senate to run for the governorship, a strategic move intended to bolster the Whig Party's influence in Kentucky and support the presidential candidacy of Zachary Taylor.
The Democratic Party nominated Lazarus W. Powell, a lawyer and state legislator. The campaign focused on issues including internal improvements, the state's financial condition, and national partisan alignment.
John J. Crittenden won the election, receiving 66,860 votes (approximately 53.8% of the total). Lazarus W. Powell received 57,397 votes (approximately 46.2%). Crittenden was inaugurated as the 17th Governor of Kentucky on September 6, 1848.
Crittenden did not serve out his full four-year term. He resigned in July 1850 to accept an appointment as U.S. Attorney General in the administration of President Millard Fillmore following the death of Zachary Taylor. He was succeeded by Lieutenant Governor John L. Helm. Lazarus W. Powell, the defeated candidate in 1848, went on to win the subsequent gubernatorial election in 1851.
