The Native American Graves Protection and Repatriation Act (NAGPRA) is a U.S. federal law passed in 1990 that requires institutions receiving federal funding to inventory their collections, consult with federally recognized Native American and Native Hawaiian tribes, and repatriate human remains and associated funerary objects, unassociated funerary objects, sacred objects, and objects of cultural patrimony to those who have requested them and have a legal right to them.
