The 61st 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, 1909, to March 4, 1911, during the first two years of William H. Taft's presidency. The apportionment of seats in the House of Representatives was based on the 1900 United States census. Both chambers had a Republican majority.
