The New York State Assembly is the lower house of the New York State Legislature, with the New York State Senate being the upper house. There are 150 seats in the Assembly. Assembly members serve two-year terms without term limits.

The New York State Legislature consists of the two houses that act as the state legislature of the U.S. state of New York: the New York State Senate and the New York State Assembly. The Constitution of New York does not designate an official term for the two houses together; it says only that the state's legislative power "shall be vested in the senate and assembly". Session laws passed by the Legislature are published in the official Laws of New York. Permanent New York laws of a general nature are codified in the Consolidated Laws of New York. As of January 2021, the Democratic Party holds supermajorities in both houses of the New York State Legislature, which is the highest paid state legislature in the country.
