79th United States Congress

The 79th 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, 1945, to January 3, 1947, during the last months of Franklin D. Roosevelt's presidency, and the first two years of Harry Truman's presidency. The apportionment of seats in this House of Representatives was based on the 1940 United States census.

Both chambers had a Democratic majority (including increasing their edge in the House). With the reelection of President Franklin D. Roosevelt to a record fourth term, the Democrats maintained an overall federal government trifecta.
