Coney Island is a peninsular residential neighborhood, beach, and leisure and entertainment destination on the Coney Island Channel. It is part of the Lower Bay in the southwestern part of the borough of Brooklyn in New York City. The site was formerly an outer barrier island but became partially connected to the rest of Long Island by land fill.

There is no clear historical consensus on how the island got the name "Coney Island", a name, in the form of Conyne Eylandt, that shows up in early 17th century Dutch maps. The most popular theory is the name came from the old spelling of the Dutch word for rabbit, "conyn", derived from a purported large population of wild rabbits, giving it the name "Rabbit Island", the name was changed to "Coney Island" after the English took over the colony in 1664, "coney" being the English version of the word rabbit.

Due to Coney Island's proximity to Manhattan and other boroughs, and its relative short distance from the city of Brooklyn to provide the illusion of a proper vacation, it began attracting vacationers in the 1830's and 1840's, assisted by carriage roads and steamship service that reduced travel time from a formerly half-day journey to two hours.

Coney Island was heavily damaged by a hurricane in 2012, but the amusement park reopened in the spring of 2013. The infamous Nathan's Hot Dog contest resumed shortly as well. Repairs on The New York Aquarium are continuing and are expected to be complete by 2018.
