The '''80th United States Congress''' was a meeting of the legislative branch of the [[Federal government of the United States|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, 1947, to January 3, 1949, during the third and fourth years of 33rd President [[Presidency of Harry S. Truman|Harry S. Truman's administration]] (1945–1952). This congressional term featured the most recent special Senate sessions. The apportionment of seats in this [[United States House of Representatives|House of Representatives]] was based on the [[1940 United States census]].

The [[Republican Party (United States)|Republicans]] won the majority in both chambers, marking the first time since the [[71st United States Congress|71st Congress]] of 1929–1931, that they held full control of Congress, and the first time since the [[72nd United States Congress|72nd Congress]] of 1931–1933, that they held control of either of the two chambers. This also ended a 14-year [[Democratic Party (United States)|Democratic]] overall federal government [[government trifecta#United States|trifecta]] period, dating back to the [[73rd United States Congress|73rd Congress]] (1933–1935). This ties with the previous 14-year [[Republican Party (United States)|Republican]] trifecta from 1897 to 1911 as the longest trifectas of Congress and is the last time, (as of the year 2024), that a trifecta was achieved that lasted longer than a decade.

Although the 80th Congress passed a total of 906 public bills,<ref>{{Cite web |title=Résumé of Congressional Activity Eightieth Congress |url=https://www.senate.gov/reference/resources/pdf/80res.pdf |publisher=United States Senate}}</ref> President Truman nicknamed it during his campaign speeches and remarks as the "'''Do Nothing Congress'''" and, during the [[1948 United States presidential election|1948 elections]], campaigned as much against it as against his formal opponent, [[Thomas E. Dewey]] of [[New York (state)|New York]]. the Republican presidential nominee. The 80th Congress did however pass several significant bills with bipartisan support, most famously the [[Truman Doctrine]] (on Greece-Turkey [[anti-communism|anti-communists]] aid in developing [[Cold War]] with former ally [[Soviet Union]]), the [[Marshall Plan]] (aid for devastated [[Europe]] after [[World War II]]), and the [[Taft–Hartley Act]] of 1947 on labor relations (over Truman's veto), but it opposed most of Truman's [[Fair Deal]] domestic programs bills.

===House of Representatives===
The names of members of the House of Representatives elected statewide ''at-large,'' are preceded by an "At-Large", and the names of those elected from districts, whether plural or single member, are preceded by their district numbers.

The congressional district numbers are linked to articles describing the district itself. Since the boundaries of the districts have changed often and substantially, the linked article may only describe the district as it exists today, and not as it was at the time of this Congress.
