The 1884 United States presidential election in Maine took place on November 4, 1884, as part of the 1884 United States presidential election. Voters chose six representatives, or electors to the Electoral College, who voted for president and vice president.

The 1884 United States presidential election was the 25th quadrennial presidential election, held on Tuesday, November 4, 1884. In the election, Governor Grover Cleveland of New York defeated Republican James G. Blaine of Maine. It was set apart by unpleasant mudslinging and shameful personal allegations that eclipsed substantive issues, such as civil administration change. Cleveland was the first Democrat elected president of the United States since James Buchanan in 1856, the first to hold office since Andrew Johnson left the White House in 1869, and the last to hold office until Woodrow Wilson, who began his first term in 1913. For this reason, 1884 is a significant election in U.S. political history, marking an interruption in the era when Republicans largely controlled the presidency between Reconstruction and the Great Depression.
