Hoffman Island, Artificial island in Lower New York Bay, United States.
Hoffman Island is an artificial landmass of approximately 11 acres situated off South Beach in Staten Island, created in 1873 through the placement of fill material on Orchard Shoal. The National Park Service now manages it as part of Gateway National Recreation Area with restricted public access.
The island was created in 1873 through landfill operations and functioned as a quarantine station from the 1870s through the early 1900s, isolating immigrants with contagious diseases. This medical role was essential during the peak immigration years when arrivals were screened before entering the United States.
The island takes its name from John Thompson Hoffman, a political leader who served as Mayor of New York City and later as Governor of New York State. This naming reflects his importance in the state's governance during the 19th century.
The island is closed to public visits as the National Park Service restricts access to protect nesting birds and wildlife. The best views come from South Beach or boat tours in Lower New York Bay.
During World War II, the island served as an anchorage point for anti-submarine nets that protected New York Bay from enemy attacks. This military infrastructure was part of a broader defense system that guarded the region's vital harbors during wartime.
