Fort de Buade was a French fort across from the northern tip of the "mitten" of the present U.S. state of Michigan. It was garrisoned between 1683 and 1701. The city of St. Ignace developed at the site, which also had the historic St. Ignace Mission founded by Jesuits. It is named after New France's governor at the time, Louis de Buade de Frontenac.
