The 1856 United States presidential election in Maryland took place on November 4, 1856, as part of the 1856 United States presidential election. Voters chose eight representatives, or electors to the Electoral College, who voted for president and vice president.
Maryland voted for the Know Nothing candidate, former president Millard Fillmore, over the Democratic candidate, James Buchanan, and Republican candidate, John C. Frémont.
Fillmore won the state by a margin of 9.59%. Maryland was the only state to vote for Fillmore this election. This was the last time until 1948 that a Democrat won the presidency without carrying Maryland.
