The Siege of Dunlap's Station was a battle that took place on January 10–11, 1791, during the Northwest Indian War between the Western Confederacy of American Indians and European-American settlers in what to became the southwestern region of the U.S. state of Ohio. This was one of the Indians' few unsuccessful attacks during this period. It was shortly after the Harmar Campaign attacks and unprecedented defeat of U.S. Army forces. A few months after the siege, the Army's St. Clair's campaign famously failed.
