New York's 63rd State Assembly district is one of the 150 districts in the New York State Assembly.

It has been represented by Republican Sam Pirozzolo since 2023, succeeding Michael Cusick, who retired in 2022.

The district consists of neighborhoods within western and central Staten Island, such as Arlington, Bloomfield, Travis, Todt Hill, Silver Hill, Chelsea, Port Ivory, Rosebank, Heartland Village and New Springville.

The district is entirely within New York's 11th congressional district, and overlaps the 23rd and 24th districts of the New York State Senate, and the 49th, 50th and 51st districts of the New York City Council.
