Following is a table of the United States presidential elections in Mississippi, in chronological order by year.

In more than two hundred years of presidential elections, they have supported the same candidate in all but one; the election of 1840, when Mississippi voted for William Henry Harrison and Alabama for Martin Van Buren (in 1868, only Alabama participated, as Mississippi had not yet been readmitted to the Union).

The result of the election, with the victory of an ardent opponent of slavery, spurred the secession of eleven states and brought about the American Civil War.

The election was the only one in history to be decided by the House of Representatives under the provisions of the Twelfth Amendment to the United States Constitution after no candidate secured a majority of the electoral vote.

It was also the only presidential election in which the candidate who received a plurality of electoral votes (Andrew Jackson) did not become president, a source of great bitterness for Jackson and his supporters, who proclaimed the election of Adams a corrupt bargain.
