The refuge was established in 1963 under the authority of the Migratory Bird Conservation Act for use as an inviolate sanctuary, or any other management purpose, for migratory birds.

Situated along the marshes of the western Delaware Bay, Prime Hook National Wildlife Refuge protects more than 10,000 acres of valuable habitat for wildlife of all kinds. Roughly 80% of the refuge is a mix of fresh and saltwater wetlands stretching from Slaughter Beach in the north to the Broadkill River in the south.
