List of islands of New York (state)

New York State boasts a diverse array of islands, ranging from small, uninhabited landmasses to large, densely populated areas. These islands are located in various bodies of water, including the Atlantic Ocean, Long Island Sound, the Hudson River, the Great Lakes (Lake Ontario and Lake Erie), and numerous inland lakes and rivers.

Islands are defined as landmasses completely surrounded by water. The size and character of New York's islands vary greatly. Some are bedrock outcrops, while others are sandy barrier islands formed by coastal processes. Their uses also differ, including residential areas, recreational spaces, wildlife preserves, and industrial sites.

Notable island regions include:

• Long Island: Technically a peninsula, but commonly referred to as an island, it is the most populous island in the United States and home to much of New York City's population (Brooklyn and Queens boroughs are on Long Island) as well as numerous suburban communities.

• New York City Islands: Beyond Long Island, New York City contains numerous smaller islands, including Manhattan Island, Staten Island, Roosevelt Island, Governors Island, and Hart Island. These islands have played significant roles in the city's history and development.

• Thousand Islands: A scenic archipelago spanning the border between New York and Ontario, Canada, in the St. Lawrence River. These islands range in size from large, inhabited islands to tiny, rocky outcroppings.

• Lake George Islands: Lake George contains numerous islands, some of which are state-owned and open for public recreation.

• Hudson River Islands: The Hudson River features many islands, some of which are important for wildlife habitat and recreation.

This list is not exhaustive, as New York State has a vast number of islands, particularly in its northern and coastal regions. The New York State Department of Environmental Conservation and various local government agencies manage many of these islands, with a focus on preserving their ecological value and providing recreational opportunities. The specific ownership and accessibility of individual islands can vary.
