Batchawana Bay is a small bay on the eastern shore of Lake Superior, approximately 50 kilometres (31 mi) north of Sault Ste. Marie, Ontario, Canada. Batchawana Bay was termed Badjiwanung by the Ojibwe, referring to water that bubbles up. This occurs between Batchawana Island and Sand Point, where the lake narrows and a strong current and undertow results. The Ojibwe believed this was caused by an underwater spirit about to surface. The bay was historically notable as the dividing point separating the two Robinson Treaty areas between the Crown and the Ojibwe people.
