The first 1800 United States Senate special election in New York was held on April 3, 1800, by the New York State Legislature to elect a U.S. Senator (Class 1) to represent the State of New York in the United States Senate.
Federalist John Sloss Hobart had been elected in January 1798 for the remainder of Philip Schuyler's term (1797–1803) but had resigned on April 16 after his appointment to the United States District Court for the District of New York. Federalist William North was appointed by Governor John Jay to fill the vacancy temporarily, and took his seat on May 21, Congress being in session until July 16, 1798. At the next meeting of the State Legislature, James Watson was elected instead of North, took his seat on December 11, 1798, but resigned on March 19, 1800, after his appointment as Naval Officer of the Port of New York.
At the State election in April 1799, Federalist majorities were elected to both houses of the 23rd New York State Legislature which met from January 28 to April 8, 1800, at Albany, New York.
Ex-U.S. Minister to France (in office 1792–1794) Gouverneur Morris was the candidate of the Federalist Party.
Gen. Peter Gansevoort was the candidate of the Democratic-Republican Party.
Morris was the choice of both the State Senate and the State Assembly, and was declared elected.

| U.S. Senator | State Senate (43 members) | Gouverneur Morris | 25 | Peter Gansevoort | 11 |
| State Assembly (107 members) | Gouverneur Morris | 54 | Peter Gansevoort | 48 | |
Morris took his seat on May 3, 1800, being the fifth holder of this seat in a single term (1797–1803), a record which still stands after more than 200 years.
