Anishinaabe or Anishinabe—or more properly Anishinaabeg or Anishinabek, which is the plural form of the word—is the autonym often used by the Odawa, Ojibwe, and Algonquin peoples. They all speak closely related Anishinaabemowin/Anishinaabe languages, of the Algonquian language family.

The meaning of Anishnaabeg is "First" or "Original-Peoples". Another definition - possibly reflecting a traditionalist's viewpoint with a certain moral dimension - refers to "the good humans", or good people, meaning those who are on the right road/path given to them by the Creator or Gichi-Manidoo (Great Spirit). The Ojibwe scholar, linguist and author Basil Johnston, who explains the name in a creationist context, states that its literal translation is "Beings Made Out of Nothing", or "Spontaneous Beings", since they had been created by divine breath and were made up of flesh and blood and a soul or spirit - instead of rock, or fire, or water, or wind.

Not all Anishinaabemowin speakers, however, call themselves Anishinaabeg. The Ojibwe people who moved to what are now the prairie provinces of Canada call themselves Nakawē(-k) and their branch of the Anishinaabe language, Nakawēmowin. (The French ethnonym for the group was the Saulteaux). Particular Anishinaabeg groups have different names from region to region.
