The 85th 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 January 3, 1957, to January 3, 1959, during the fifth and sixth years of Dwight Eisenhower's presidency. The apportionment of seats in the House of Representatives was based on the 1950 United States census. Both chambers had a Democratic majority. To date, this is the earliest Congress with a member still living, Merwin Coad.
