The Treaty of Detroit was a treaty between the United States and the Ottawa, Chippewa, Wyandot, and Potawatomi Native American nations. The treaty was signed in Detroit, Michigan on November 17, 1807, with William Hull, governor of the Michigan Territory and superintendent of Indian affairs, the sole representative of the U.S.

With this treaty, these Native American tribes ceded claim to a large portion of land in what is now Southeast Michigan and northwest Ohio.
