As a federal agency that manages public land and cares for public collections containing Native American human remains, funerary objects, sacred objects, and objects of cultural patrimony, the National Park Service must comply with the Native American Graves Protection and Repatriation Act (NAGPRA).

Over 100 NPS units have completed NAGPRA inventories and 349 NPS units are represented on the national NAGPRA summary completed and distributed in 1993. Nearly 6,000 sets of Native American human remains and over 82,000 associated funerary objects are listed in the inventories prepared and distributed to Indian tribes, Native Alaskan entities, and Native Hawaiian organizations, as required by the law. As of August, 2003, National Park Service units have published Notices of Inventory Completion covering 3,609 sets of Native American human remains (60% of the total) and 75,663 associated funerary objects.
