The 1820 United States presidential election was the ninth quadrennial presidential election. It was held from Wednesday, November 1, to Wednesday, December 6, 1820. Taking place at the height of the Era of Good Feelings, the election saw incumbent Democratic-Republican President James Monroe win re-election without a major opponent. It was the third and the most recent United States presidential election in which a presidential candidate ran effectively unopposed. As of 2024, this is the most recent presidential election where an incumbent president was re-elected who was neither a Democrat nor a Republican, before the Democratic-Republican party split into separate parties. James Monroe's re-election marked the first time in U.S. history that a third consecutive president won a second election. This happened again with Barack Obama's re-election in the 2012 election and at no other point have multiple consecutive presidents won two elections.
The tables below list the United States presidential elections in Missouri, ordered by year. Since 1904, Missouri has voted for the eventual winner of the presidential election with only four exceptions: 1956, 2008, 2012, and 2020, although the popular vote winner failed the win the electoral vote in 2000 and 2016. Missouri was historically viewed as a bellwether state, but the consecutive votes against the winning candidate in 2008 and 2012 introduced doubts about its continued status as a bellwether, and an 18.5-point Republican victory in 2016 indicated that it had become a safe red state.
