The 35th United States Congress was a meeting of the legislative branch of the United States federal government, consisting of the United States Senate and the United States House of Representatives. It met in Washington, D.C. from March 4, 1857, to March 4, 1859, during the first two years of James Buchanan's presidency. The apportionment of seats in the House of Representatives was based on the 1850 United States census. Both chambers had a Democratic majority.
