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 land fill, the island is named for former New York City mayor (1866–1868) and New York Governor (1869–1871) John Thompson Hoffman.
