The Sixty-eighth United States Congress 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. Both chambers had a Republican majority.
