The 2nd United States Congress, consisting of the United States Senate and the United States House of Representatives, met at Congress Hall in Philadelphia, Pennsylvania, from March 4, 1791, to March 4, 1793, during the third and fourth years of George Washington's presidency. The apportionment of seats in the House of Representatives was based on the provisions of Article I, Section 2, Clause 3 of the United States Constitution. Additional House seats were assigned to the two new states of Vermont and Kentucky. Both chambers had a Pro-Administration majority.

The 1792–93 United States Senate elections were held on various dates in various states, coinciding with President George Washington's unanimous re-election. As these U.S. Senate elections were prior to the ratification of the Seventeenth Amendment in 1913, senators were chosen by state legislatures. Senators were elected over a wide range of time throughout 1792 and 1793, and a seat may have been filled months late or remained vacant due to legislative deadlock. In these elections, terms were up for the ten senators in Class 2.
