The seventy-third United States Congress was a meeting of the legislative branch of the United States federal government, composed of the United States Senate and the United States House of Representatives. It met in Washington, D.C. from March 4, 1933 to January 3, 1935, during the first two years of Franklin D. Roosevelt's presidency. Because of the newly ratified 20th Amendment, the duration of this Congress, along with the term of office of those elected to it, was shortened by the interval between January 3 and March 4, 1935 (61 days). The apportionment of seats in the House of Representatives was based on the Fifteenth Census of the United States in 1930. Both chambers had a Democratic majority.
