Ottawa or Odawa is a dialect of the Ojibwe language spoken by the Odawa people in southern Ontario in Canada, and northern Michigan in the United States. Descendants of migrant Ottawa speakers live in Kansas and Oklahoma. The first recorded meeting of Ottawa speakers and Europeans occurred in 1615 when a party of Ottawas encountered explorer Samuel de Champlain on the north shore of Georgian Bay. Ottawa is written in an alphabetic system using Latin letters, and is known to its speakers as Nishnaabemwin 'speaking the native language' or Daawaamwin 'speaking Ottawa'.

Ojibwe, also known as Ojibwa, Ojibway, Otchipwe, Ojibwemowin, or Anishinaabemowin, is an indigenous language of North America of the Algonquian language family. The language is characterized by a series of dialects that have local names and frequently local writing systems. There is no single dialect that is considered the most prestigious or most prominent, and no standard writing system that covers all dialects.
