The Treaty of Fort Harmar was an agreement between the United States government and numerous Native American tribes with claims to the Northwest Territory. It was signed at Fort Harmar, near present-day Marietta, Ohio, on January 9, 1789. Representatives of the Iroquois Six Nations and other groups, including the Wyandot, Delaware, Ottawa, Chippewa, Potawatomi and Sauk met with Arthur St. Clair, the governor of the Northwest Territory, and other American leaders such as Josiah Harmar and Richard Butler.
