Lyng v. Northwest Indian Cemetery Protective Association, 485 U.S. 439 (1988), was a United States Supreme Court landmark case in which the Court ruled on the applicability of the Free Exercise Clause to the practice of religion on Native American sacred lands, specifically in the Chimney Rock area of the Six Rivers National Forest in California. This area, also known as the High Country, was used by the Yurok, Karuk, and Tolowa tribes as a religious site. The ruling is considered a key example of judicial restraint by the Supreme Court.
