Coney Island is a peninsula and beach on the Atlantic Ocean in southern Brooklyn, New York, United States. The site was formerly an island, but became partially connected to the mainland by landfill.
Coney Island is possibly best known as the site of amusement parks and a major resort that reached their peak during the first half of the 20th century. It declined in popularity after World War II and endured 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 neighborhood of the same name is a community of 60,000 people in the western part of the peninsula, with Sea Gate to its west, Brighton Beach and Manhattan Beach to its east, and Gravesend to the north.
