76th United States Congress

The 76th 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, 1939, to January 3, 1941, during the seventh and eighth years of Franklin D. Roosevelt's presidency. The apportionment of seats in the House of Representatives was based on the 1930 United States census.

Both chambers had a Democratic majority - holding a supermajority in the Senate, but a greatly reduced majority in the House, thus losing the supermajority there. With President Roosevelt, the Democrats maintained an overall federal government trifecta.

The 76th is also the most recent Congress to have held a third session.
