Smith Point County Park is a beachfront park facing the Atlantic Ocean on the east end of Fire Island, along the central south shore of Long Island, near Shirley, New York, United States. It is the largest park owned by Suffolk County.
The park derives its name from Smith Point, a peninsula on the Long Island mainland that extends into Bellport Bay. The peninsula was named for William "Tangier" Smith, who in the 17th century owned 50 miles of ocean-front property in the Manor of St. George. The park is not on the Smith Point peninsula.
