The Government of the State of New York, headquartered at the New York State Capitol in Albany, encompasses the administrative structure of the U.S. state of New York, as established by the state's constitution. Analogously to the US federal government, it is composed of three branches: executive, legislative, and judicial. The head of the executive is the governor. The Legislature consists of the Senate and the Assembly. The Unified Court System consists of the Court of Appeals and lower courts. The state is also divided into counties, cities, towns, and villages, which are all municipal corporations with their own government.

The New York State Capitol, the seat of the New York state government, is located in Albany, the capital city of the U.S. state of New York. The capitol building is part of the Empire State Plaza complex on State Street in Capitol Park. Housing the New York State Legislature, the building was completed in 1899 at a cost of US$25 million, making it the most expensive government building of its time. It was listed on the National Register of Historic Places in 1971, then included as a contributing property when the Lafayette Park Historic District was listed in 1978. The New York State Capitol was declared a National Historic Landmark in 1979.
