The 68th 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, 1923, to March 4, 1925, during the last months of Warren G. Harding's presidency, and the first years of the administration of his successor, Calvin Coolidge. The apportionment of seats in the House of Representatives was based on the thirteenth decennial census of the United States in 1910.
