NAGPRA stands for The Native American Graves Protection and Repatriation Act. The following is taken from _CRM_ Volume 17 No. 6 1994: Archeology and the Federal Government. The Native American Graves Protection and Repatriation Act (P.L. 101-601; 104 Stat. 3048, 25 USC 3001 note.), signed into law on November 16, 1990, requires Federal agencies and museums to inventory human remains and associated funerary objects and to provide culturally affiliated tribes with the inventory of collections. The Act requires repatriation, on request, to the culturally affiliated tribes and establishes a grant program within the Department of the Interior to assist tribes and Native Hawaiian organizations in repatriation and to assist museums in preparing the inventories and collections summaries. It also makes the sale or purchase of Native American human remains, whether or not they derive from Federal or Indian lands, illegal.
