The Northwestern Confederacy, or Northwestern Indian Confederacy, was a loose confederacy of Native Americans in the Great Lakes region of the United States created after the American Revolutionary War. Formally, the confederacy referred to itself as the United Indian Nations at their Confederate Council. It was known infrequently as the Miami Confederacy since many contemporaneous federal officials overestimated the influence and numerical strength of the Miami tribes based on the size of their principal city, Kekionga.
