The Bombay Hook National Wildlife Refuge is a 15,978 acres National Wildlife Refuge located along the eastern coast of Kent County, Delaware, United States, on Delaware Bay. It was established on March 16, 1937 as a refuge and breeding ground for migratory and wintering waterfowl along the Atlantic Flyway. The Refuge was purchased from local land owners with federal duck stamp funds.
Today, the refuge protects wildlife of all kinds, with emphasis on all migratory birds. The refuge also contains the Allee House, a pre-revolutionary war farmhouse on the National Register of Historic Places. It is a stop on Delaware's Coastal Heritage Greenway.
