New York's 10th congressional district is a congressional district for the United States House of Representatives currently represented by Democrat Dan Goldman. The district contains all of Lower Manhattan and the western Brooklyn neighborhoods of Brooklyn Heights, DUMBO, Cobble Hill, Red Hook, Gowanus, Prospect Heights, Park Slope, and Sunset Park. The district also contains portions of Borough Park and Bay Ridge in Brooklyn, and all of Prospect Park. In Upper New York Harbor, the district includes Governors Island, Liberty Island and the Statue of Liberty, and parts of Ellis Island.

This congressional district has changed configurations and locations many times throughout its history due to redistricting, initially starting out as an upstate constituency before gradually moving south. Beginning in the 1870s, it shifted into parts of New York City, where it has remained to this day.

In the 20th century, the 10th district was always a Brooklyn-based seat from 1913 until 1973, when that iteration of the district was redrawn and renumbered as the new 16th, and the 10th was reassigned to a district in northern Queens and the east Bronx. The 1980 redistricting cycle restored the 10th district to Brooklyn, covering largely the same terrain as before. In the 1990 remap, much of the old 10th district was added to the new Queens–Brooklyn 9th district, while the new 10th then absorbed much of the old 11th district, including its congressman, Ed Towns.

From 2003 to 2013, this district was exclusively Brooklyn-based. During this time, it was majority-African American and included the neighborhoods of Bedford-Stuyvesant, Brooklyn Heights, Brownsville, Canarsie, East New York, and Ocean Hill, as well as parts of Fort Greene, Prospect Heights, and Williamsburg.^[4] Following the 2010–12 redistricting cycle, the district shed most of its Brooklyn territory, and picked up parts of Manhattan that had been in the 8th district.

The 2010 map had a size of 14.25 sq mi (36.9 km²), New York's 10th district was the second-smallest by total area in the country, after New York's 13th.^[5] Demographically, it also had the largest number (197,000 or 270,000) and the highest percentage of Jews (27.5% or 37.6%)^{[lower-alpha 1]} of any congressional district,^[6] largely as a result of the fact that it included several heavily Jewish neighborhoods of Manhattan and Brooklyn. Prior to the 2020 census, the district stretched from the Upper West Side of Manhattan to Borough Park.
