The 1843 Vermont gubernatorial election was held on September 5, 1843.
Incumbent Whig Governor Charles Paine did not run for re-election.
Whig nominee John Mattocks defeated Democratic nominee Daniel Kellogg and Liberty nominee Charles K. Williams.
Since no candidate received a majority in the popular vote, Mattocks was elected by the Vermont General Assembly per the state constitution.
As no candidate received a majority of the vote, the Vermont General Assembly was required to decide the election, both Houses meeting jointly choosing among the top three vote-getters, Mattocks, Kellogg, and Williams. The legislative election was held on October 12, 1843.
