# New York's 21st congressional district

New York's 21st congressional district is a congressional district for the United States House of Representatives that is represented by Republican Elise Stefanik. On November 11, 2024, President Donald Trump announced his intention to nominate Stefanik to serve as the United States Ambassador to the United Nations. If confirmed by the Senate, this would create a vacancy in her district, prompting a special election to fill the seat.
The district is primarily rural, but it also includes the cities of Ogdensburg, Glens Falls, Rome, and Plattsburgh. The district includes most of the Adirondack Mountains and the Thousand Islands region. It borders Vermont to the east and Canada to the north. It also includes Fort Drum of the U.S. Army.

## History

From 2003 to 2013, the district with that number contained most of the Capital District of New York. It included all or parts of Albany, Fulton, Montgomery, Rensselaer, Saratoga, Schenectady, and Schoharie counties. It contained the cities of Albany, Schenectady, Troy, Amsterdam, Cohoes, Watervliet, Gloversville, and Johnstown. Up until 1980, the 21st district was located in Upper Manhattan (including parts of Harlem and Washington Heights), and The Bronx.
From 2013 to present: Clinton, Essex, Franklin, Fulton, Hamilton, Herkimer, Lewis, Montgomery, Schoharie, St. Lawrence, Warren, and Washington counties, and parts of Jefferson, Otsego, and Rensselaer counties.
