Wilson v. Omaha Tribe, 442 U.S. 653 (1979), was a case in which the Supreme Court of the United States held that in a land dispute, 25 U.S.C. § 194. applied only to individuals and not a state, that federal law governed the tribe's right to possession, but that state law was to be used in determining how that applied to the natural movement of a river's boundaries..
