A wigwam, wickiup, wetu (Wampanoag), or wiigiwaam is a semi-permanent domed dwelling formerly used by certain Native American tribes and First Nations people and still used for ceremonial events. The term wickiup is generally used to refer to these kinds of dwellings in the Southwestern United States and Western United States and Northwest Alberta, Canada, while wigwam is usually applied to these structures in the Northeastern United States as well as Ontario and Quebec in central Canada. The names can refer to many distinct types of Indigenous structures regardless of location or cultural group. The wigwam is not to be confused with the Native Plains tipi, which has a different construction, structure, and use.
