The 1790–91 United States Senate elections were held on various dates in various states. These U.S. Senate elections occurred during the first midterm election cycle, which took place in the middle of President George Washington's first term. As these 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 1790 and 1791, and a seat may have been filled months late or remained vacant due to legislative deadlock.^[1] In these elections, terms were up for the nine senators in Class 1.

As of these elections, formal organized political parties had yet to form in the United States, but two political factions were present: The coalition of senators who supported President Washington's administration were known as the Pro-Administration Party, and the senators against him as the Anti-Administration Party.

Note: There were no political parties in this Congress. Members are informally grouped into factions of similar interest, based on an analysis of their voting record.^[2]

The election in New York was held January 19, 1791, by the New York State Legislature.

Incumbent Philip Schuyler's term would expire March 3, 1791.

At the State election in April 1790, nominal Federalist majorities were elected to both houses of the 14th New York State Legislature, but many Federalists were friendly to the Democratic-Republican Governor George Clinton, party lines not being drawn very strictly then.

The incumbent Philip Schuyler ran for re-election as the candidate of the Federalist Party. New York State Attorney General Aaron Burr was the candidate of the Democratic-Republican Party, but was at that time a rather moderate politician, opposing the ultras of both parties.

Burr was the choice of both the State Senate and the State Assembly, and was declared elected. Schuyler was defeated despite the nominal majority of his party. Many of the Federalists took the opportunity to show their disapproval of both Schuyler's haughtiness and the financial policies of Alexander Hamilton, the U.S. Secretary of the Treasury and Schuyler's son-in-law. Besides, the Livingston faction of the Federalist Party felt betrayed after the election of Rufus King over their candidate James Duane in 1789, and now allied themselves with Clinton and later became Democratic-Republicans.

Obs.: Burr had a majority of 5 votes in the Assembly, but the exact number of votes is unclear.

In 1791, the legislature failed to elect due to a disagreement on procedure.^[10] The seat would remain vacant until 1793.^[10]

Stephen R. Bradley and Moses Robinson were elected by the Vermont House of Representatives and Governor and Council in January 1791, anticipating Vermont's admission to the union.^[11] Vermont was admitted as the 14th state on March 4, 1791.^[12] The Senate had adjourned on March 3, at the completion of the 1st United States Congress; the 2nd United States Congress held a one-day session on March 4, and was not scheduled to convene again until October 24.^[13]

As a result of this congressional schedule Bradley and Robinson had not been seated when the Vermont House of Representatives convened in early October, 1791.^[12] At this legislative session, some members suggested that the January election of Bradley and Robinson had been premature, since Vermont had not yet been admitted to the union.^[12] Bradley and Robinson volunteered to resign the credentials of their January elections; on October 17, the Governor and Council voted again, and selected Bradley and Robinson.^[12] The House of Representatives then voted a second time, and also selected Bradley and Robinson.^[12] No vote totals were recorded.^[12]

Bradley was selected for the "short term" (Class 3), which expired on March 3, 1795.^[14] Robinson received the "long term" (Class 1), which expired on March 3, 1797.^[15]

William Grayson died March 12, 1790, and John Walker was appointed to continue the term.

Future President James Monroe was elected in November 1790 to finish the term.

Monroe was re-elected in 1791 to the next term, as well.
