Park Slope is a neighborhood in western Brooklyn, New York City, within the area once known as South Brooklyn. Park Slope is roughly bounded by Prospect Park and Prospect Park West to the east, Fourth Avenue to the west, Flatbush Avenue to the north, and Prospect Expressway to the south. Generally, the section from Flatbush Avenue to Garfield Place is considered the "North Slope", the section from 1st to 9th Street is considered the "Center Slope", and south from 9th Street, the "South Slope". The neighborhood takes its name from its location on the western slope of neighboring Prospect Park. Fifth Avenue and Seventh Avenue are its primary commercial streets, while its east–west side streets are lined with brownstones and apartment buildings.
