The Midewiwin or the Grand Medicine Society is a religion of some of the Indigenous peoples of the Maritimes, New England and Great Lakes regions in North America. Its practitioners are called Midew, and the practices of Midewiwin are referred to as Mide. Occasionally, male Midew are called Midewinini, which is sometimes translated into English as "medicine man".

Ojibwe is an indigenous language of North America from the Algonquian language family. Ojibwe is one of the largest Native American languages north of Mexico in terms of number of speakers and is characterized by a series of dialects, some of which differ significantly. The dialects of Ojibwe are spoken in Canada from southwestern Quebec, through Ontario, Manitoba and parts of Saskatchewan, with outlying communities in Alberta and British Columbia, and in the United States from Michigan through Wisconsin and Minnesota, with a number of communities in North Dakota and Montana, as well as migrant groups in Kansas and Oklahoma.
