The 1856 United States presidential election in Missouri was held on November 4, 1856. Voters chose nine electors to represent the state in the Electoral College, which chose the president and vice president.
As of the 2020 presidential election[update], this is the last time Gasconade County voted for a Democratic presidential candidate, which, as of 2023, makes it the longest Republican winning streak in presidential elections in the nation.[2]
