The 4th New York State Legislature, consisting of the New York State Senate and the New York State Assembly, met from September 7, 1780, to July 1, 1781, during the fourth year of George Clinton's governorship, first at Poughkeepsie, then at Albany, and finally at Poughkeepsie again.

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.

On May 8, 1777, the Constitutional Convention had appointed the senators from the Southern District, and the assemblymen from Kings, New York, Queens, Richmond and Suffolk counties—the area which was under British control—and determined that these appointees serve in the Legislature until elections could be held in those areas, presumably after the end of the American Revolutionary War. Vacancies among the appointed members in the Senate should be filled by the Assembly, and vacancies in the Assembly by the Senate.

The State elections were held from April 25 to 27, 1780. Gov. George Clinton and Lt. Gov. Pierre Van Cortlandt were re-elected. Under the determination by the Constitutional Convention, the senators William Floyd, William Smith and Isaac Stoutenburgh, whose seats were up for election, continued in office, as well as the assemblymen from Kings, New York, Queens, Richmond and Suffolk counties. Arthur Parks (Middle D.) was re-elected. Philip Schuyler was elected in the Western District. Assemblyman Elkanah Day, from Cumberland County, which had seceded from New York to become a part of the Vermont Republic, was elected in the Eastern District.
