Brighton Beach is a neighborhood in the southern portion of the New York City borough of Brooklyn, within the greater Coney Island area along the Atlantic Ocean coastline. Brighton Beach is bounded by Coney Island proper at Ocean Parkway to the west, Manhattan Beach at Corbin Place to the east, Sheepshead Bay at the Belt Parkway to the north, and the Atlantic Ocean to the south along the beach and boardwalk.

Coney Island is a peninsular neighborhood and entertainment area in the southwestern section of the New York City borough of Brooklyn. The neighborhood is bounded by Brighton Beach to its east, Lower New York Bay to the south and west, and Gravesend to the north and includes the subsection of Sea Gate on its west. More broadly, the Coney Island peninsula consists of Coney Island proper, Brighton Beach, and Manhattan Beach. This was formerly the westernmost of the Outer Barrier islands on the southern shore of Long Island, but in the early 20th century it became a peninsula, connected to the rest of Long Island by land fill.
