The 1876 Democratic National Convention assembled in St. Louis just nine days after the conclusion of the Republican National Convention in Cincinnati.

The 1876 Republican National Convention was a presidential nominating convention held at the Exposition Hall in Cincinnati, Ohio on June 14–16, 1876. President Ulysses S. Grant had considered seeking a third term, but with various scandals, a poor economy and heavy Democratic gains in the House of Representatives that led many Republicans to repudiate him, he declined to run. The convention resulted in the nomination of Governor Rutherford B. Hayes of Ohio for president and Representative William A. Wheeler of New York for vice president.
