Islands of New York City are the dozens of natural and artificial landforms in and around New York Harbor, East River, Hudson River, and Long Island Sound that are politically and geographically part of New York City. These islands include large urban centers like Manhattan and Staten Island alongside small uninhabited islets such as North Brother Island, South Brother Island, and Hoffman Island, and feature sites connected with Ellis Island, Governor's Island, Rikers Island, and Roosevelt Island. They have shaped the development of New Amsterdam, New York State, United States maritime commerce, and modern projects involving Port Authority of New York and New Jersey, New York City Department of Parks and Recreation, and civic planning agencies.

Geography and Geology

The islands occupy glacially carved and tidal landscapes in the confluence of the Hudson River, East River, and Upper New York Bay, reflecting Pleistocene glaciation, postglacial rebound, and Holocene sedimentation that influenced Long Island and Manhattan Schist. Geologic substrates such as Manhattan schist, Inwood marble, and Tuckahoe marble underlie Manhattan, Staten Island, and Bedrock exposures visible near Fort Totten and Ellis Island. Tidal action from the Atlantic Ocean and channelization by early colonial projects around New Amsterdam and New York Harbor altered shoals near Governor's Island, Liberty Island, and the Narrows, affecting navigation managed by the United States Army Corps of Engineers and the Port Authority of New York and New Jersey.

Before European contact, islands in the estuary were inhabited and used seasonally by Lenape bands associated with villages such as Kannawha? and navigational routes leading to Lenapehoking; archaeological sites on Manhattan and Ellis Island reveal pre-contact camps and shell middens linked to Lenape fishing and trade networks. Dutch settlement under Peter Stuyvesant transformed islands like Governors Island and Manhattan during the New Netherland era, while English control after the Second Anglo-Dutch War and events like the American Revolutionary War repurposed islands for fortifications at Fort Jay, Castle Clinton, and Fort Wadsworth. 19th- and 20th-century immigration via Ellis Island and quarantine at North Brother Island and Hoffman Island tied islands to public health responses led by institutions such as the Marine Hospital Service and later United States Public Health Service.

New York City's five boroughs are each associated with principal islands: Manhattan (Manhattan Island and adjacent islets), Brooklyn (western Long Island shore and islands like Coney Island), Queens (western Long Island including Rikers Island and Flushing Bay islands), The Bronx (western Long Island Sound islands and City Island), and Staten Island (Richmond County). Prominent islands include Liberty Island (home of the Statue of Liberty), Ellis Island (Ellis Island Immigrant Hospital), Roosevelt Island (formerly Welfare Island), Governor's Island (National Monument and parkland), Randalls and Wards Islands (merged urban park complex), Coney Island (amusement district), and Hart Island (municipal burial ground).

Bridges, tunnels, ferries, and causeways link islands: Brooklyn Bridge, Manhattan Bridge, Williamsburg Bridge, Queensboro Bridge, Verrazzano-Narrows Bridge, Goethals Bridge, and Throgs Neck Bridge connect boroughs and island corridors, while Holland Tunnel, Lincoln Tunnel, and Queens Midtown Tunnel (midtown tunnels) facilitate vehicular access to Manhattan. Public transit agencies like the Metropolitan Transportation Authority operate subway lines to Manhattan, Brooklyn, and Queens and the Staten Island Railway serves Staten Island. Ferries such as the Staten Island Ferry, NYC Ferry, and historic services to Governors Island and Ellis Island integrate ports managed by the Port Authority of New York and New Jersey and local operators, while airports on adjacent islands include LaGuardia Airport and John F. Kennedy International Airport on Jamaica Bay landforms.

Islands host native and migratory species and protected habitats under management by New York City Department of Parks and Recreation, National Park Service, and organizations like the New York Botanical Garden through urban conservation at Pelham Bay Park and Inwood Hill Park. Salt marshes, eelgrass beds, and bird refuges on Great Kills Harbor, Jamaica Bay Wildlife Refuge (part of Gateway National Recreation Area), and the Pelham Islands support species monitored by Audubon Society chapters, New York-New Jersey Harbor Estuary Program, and university researchers from Columbia University and Stony Brook University. Park projects on Governors Island and Randalls and Wards Islands combine recreation with storm resiliency plans coordinated with Federal Emergency Management Agency initiatives.

Extensive reclamation and landfill projects during the 19th and 20th centuries enlarged areas such as Battery Park City, Jamaica Bay infill for John F. Kennedy International Airport, and artificial islands like Floyd Bennett Field alterations; developers, municipal agencies, and federal entities such as the Army Corps of Engineers shaped shorelines for port facilities, industrial waterfronts, and residential neighborhoods. Redevelopment efforts converted military bases like Governors Island and Fort Wadsworth into public spaces and cultural sites overseen by entities including the Trust for Governors Island and NYC Economic Development Corporation, while controversies over projects at South Street Seaport, Coney Island, and Willets Point involved preservationists, community boards, and landmark reviews by the New York City Landmarks Preservation Commission.

Islands have anchored commerce, immigration, defense, and culture: Manhattan as a global financial center with Wall Street and New York Stock Exchange, Ellis Island as a symbol of immigration law and the Immigration Act of 1924 era, Coney Island as an entertainment locus tied to Luna Park and amusement inventors, and Staten Island with maritime industries at Howland Hook Marine Terminal. Islands host museums and institutions such as the Statue of Liberty National Monument, American Museum of Natural History outreach, New York Historical Society programming, and festivals on Governor's Island and Coney Island that engage tourists, maritime commerce, and cultural tourism coordinated with NYC & Company and regional chambers of commerce.
