A potlatch is a gift-giving feast practiced by indigenous peoples of the <u><em>Pacific Northwest</em></u> Coast of Canada and the United States, among whom it is traditionally the primary economic system. This includes the Heiltsuk, Haida, Nuxalk, Tlingit, Makah, Tsimshian, Nuu-chah-nulth, Kwakwaka'wakw, and Coast Salish cultures. Potlatches are also a common feature of the peoples of the Interior and of the Subarctic adjoining the Northwest Coast, though mostly without the elaborate ritual and gift-giving economy of the coastal peoples.
