Coney Island is a peninsula and beach on the Atlantic Ocean in southern Brooklyn, New York City.
Coney Island is the westernmost part of the barrier islands of Long Island, about 4 miles (6.4 km) long and 0.5 miles (0.80 km) wide. Formerly it was an island, separated from the main part of Brooklyn by Coney Island Creek, which was partially tidal mudflats, but it has since been developed into a peninsula. There were plans early in the 20th centuryto dredge and straighten the creek as a ship canal, but they were abandoned, and the center of the creek was filled in for construction of the Belt Parkway before World War II.
The western and eastern ends are now peninsulas.
Coney Island is well known as the site of amusement parks and a seaside resort. The attractions reached their peak during the first half of the 20th century, declining in popularity after World War II and years of neglect. In recent years, the area has seen the opening of MCU Park and has become home to the minor league baseball team the Brooklyn Cyclones.
The residential neighborhood of the same name is a community of 60,000 people in thewestern part of the peninsula, with Sea Gate to its west, Brighton Beach and Manhattan Beach to its east, and Gravesend to the north.
