Can tribes claim ownership of artifacts in private collections?

What the Law Says

The Native American Graves Protection and Repatriation Act (NAGPRA) defines key terms and sets the scope of its application. Crucially, it does not extend to privately owned items.

NAGPRA establishes procedures for returning Native American cultural items—including human remains, funerary objects, sacred objects, and objects of cultural patrimony—to lineal descendants, culturally affiliated Indian tribes, and Native Hawaiian organizations.

However, the law applies only to federal agencies and institutions that receive federal funding (e.g., museums). It does not authorize tribes to claim ownership of items held in purely private collections—even if those items were originally removed from tribal lands or graves.

The statute’s definitions clarify what qualifies as protected property—but they do not create new property rights against private individuals.

Statutory Text

"Native American cultural property" means cultural items which are: (1) associated with a burial site; (2) associated with a sacred site; or (3) associated with an object of cultural patrimony, as defined in paragraph (3).

— 25 U.S.C. § 3001 — Definitions

Statutory Text

"Object of cultural patrimony" means an object having ongoing historical, traditional, or cultural importance central to the Native American group or culture itself, rather than property owned by an individual Native American, and which, therefore, cannot be alienated, appropriated, or conveyed by any individual.
