The 22nd New York State Legislature, consisting of the New York State Senate and the New York State Assembly, met from August 9, 1798, to April 3, 1799, during the fourth year of John Jay's governorship, in Albany.

Under the provisions of the New York Constitution of 1777, amended by the re-apportionment of March 4, 1796, Senators were elected on general tickets in the senatorial districts for four-year terms. They were divided into four classes, and every year about one fourth of the Senate seats came up for election. 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. In 1797, Albany was declared the State capital, and all subsequent Legislatures have been meeting there ever since.

On April 26, 1797, State Senator Joshua Sands was appointed as Collector of the Port of New York; and on September 24, 1797, State Senator Andrew Onderdonk died; leaving two vacancies in the Southern District.

U.S. Senator John Sloss Hobart (Fed.) vacated his seat on April 16, 1798, when he was appointed to the United States District Court for the District of New York, and on May 5, Gov. John Jay appointed William North (Fed.) to fill the vacancy temporarily.

In 1798, Chenango County was created from parts of Herkimer and Tioga counties, and was apportioned two seats in the Assembly, one each taken from Herkimer and Tioga. Oneida County was created from Herkimer, and was apportioned three seats in the Assembly, taken from Herkimer. Rockland County was created from Orange County, and was apportioned one seat in the Assembly, taken from Orange. Besides, two seats from Ulster Co. and one seat from Albany Co. were transferred to Orange Co.
