1800 United States presidential election in Tennessee

The 1800 United States presidential election in Tennessee took place between October 31 and December 3, 1800, as part of the 1800 United States presidential election.

Tennessee voted for the Democratic-Republican candidate, Thomas Jefferson, over Incumbent Federalist President John Adams, but the exact election results are unknown. Jefferson did, however, win all three electoral votes.

Tennessee used an electoral district system to choose its electors, with each district electing a single elector. This is similar to the way Nebraska and Maine choose their electors in modern elections.
