Hoffman Island is an 11-acre (4.5 ha) artificial island in the Lower New York Bay, off the South Beach of Staten Island, New York City. A smaller, 4-acre (1.6 ha) artificial island, Swinburne Island, lies immediately to the south. Created in 1873 upon the Orchard Shoal by the addition of landfill, the island is named for former New York City mayor (1866–1868) and New York Governor (1869–1871) John Thompson Hoffman.
During the late 1800s and early 1900s, Hoffman (and Swinburne) Island was used as a quarantine station, housing immigrants who, upon their arrival at the immigrant inspection station at nearby Ellis Island, presented with symptoms of contagious disease(s).
World War II
Starting in 1938 and extending through World War II, the United States Merchant Marine used Hoffman and Swinburne Islands as a training station. The Quonset huts built during this period are no longer evident on Hoffman Island, but as of 2017 their remnants remain on Swinburne Island. During World War II the islands also served as anchorages for Antisubmarine Nets intended to protect New York Bay and its associated shipping/naval activities from enemy submarines entering from the Atlantic Ocean.
Post–World War II
Since World War II several proposals for utilizing Hoffman and Swinburne Islands have been presented. In the 1950s, city planner Robert Moses and political consultant Bernard Baruch advocated transforming the islands into a city park, but this plan was not realized. In 1961, all existing buildings on Hoffman Island were razed. In the 1980s, in response to plans of New York City to open new homeless shelters amidst Staten Island's residential neighborhoods, some of the potentially affected residents proposed a never-implemented plan to construct a homeless shelter on Hoffman Island, Swinburne Island or both.
Hoffman and Swinburne islands are currently managed by the National Park Service as part of the Staten Island Unit of Gateway National Recreation Area. To protect the islands' avian residents, which include great egret, snowy egret, black-crowned night heron, glossy ibis, double-crested cormorant and great black-backed gull, the island is off limits to the public. Beginning in 2001, harbor seals have been observed wintering on and near the islands.

April 23, 1863, what is now known as the General Quarantine Act was passed, defining the quarantine establishment, authorizing its construction, creating the permanent office of Quarantine Commissioner, defining the duties and powers of the Commissioners and Health Officer, and establishing a general system of quarantine for the port. Additional powers were conferred by amendments made to this general act in 1864, 1865, 1866, and 1867, under which two small steamers were purchased; the property at Tompkinsville, Staten Island, known as the Marine Hospital Grounds, was sold; and the artificial islands in the lower bay were undertaken and afterward completed – Swinburne Island in 1860, and Hoffman Island in 1873.

The inhabitants of Hoffman and Swinburne Islands, man-made piles in Lower New York Bay off Staten Island, have tended to be there not because they particularly want to be, but because they have to. In the 19th century, the islands were a holding area for new immigrants feared to be carrying diseases. Later, they housed soldiers with venereal disease, quarantined parrots and, until the 1940s, merchant marines in training.
