The 10th New York State Legislature, consisting of the New York State Senate and the New York State Assembly, met from January 12 to April 21, 1787, during the tenth year of George Clinton's governorship, at the Old Royal Exchange in New York City.
Under the provisions of the New York Constitution of 1777, the State Senators were elected on general tickets in the senatorial districts, and were then divided into four classes. Six senators each drew lots for a term of 1, 2, 3 or 4 years and, beginning at the election in April 1778, every year six Senate seats came up for election to a four-year term. Assemblymen were elected countywide on general tickets to a one-year term, the whole assembly being renewed annually.
In March 1786, the Legislature enacted that future Legislatures meet on the first Tuesday of January of each year unless called earlier by the governor. No general meeting place was determined, leaving it to each Legislature to name the place where to reconvene, and if no place could be agreed upon, the Legislature should meet again where it adjourned.
The State election was held from April 25 to 27, 1786. Gov. George Clinton and Lt. Gov. Pierre Van Cortlandt were re-elected to a fourth term. Senators Lewis Morris (Southern D.), John Williams (Eastern D.) and Abraham Yates Jr. (Western D.) were re-elected; and John Hathorn (Middle D.), Peter Schuyler (Western D.) and Assemblyman John Vanderbilt (Southern D.), were elected to the Senate.
The State Legislature was to meet on January 2, 1787, at the Old Royal Exchange in New York City, but the Assembly first assembled a quorum on January 12, the Senate on January 13; both Houses adjourned on April 21, 1787.
