A wigwam, wickiup or wetu is a domed room dwelling formerly used by certain Native American and Canadian First Nations tribes, and still used for ceremonial purposes. The term wickiup is generally used to label these kinds of dwellings in the Southwestern United States and West. Wigwam is usually applied to these structures in the Northeastern United States and Canada. Wetu is the Wampanoag term for a wigwam dwelling. The use of these terms can refer to many distinct types of Native American structures regardless of location or cultural group. The wigwam is not to be confused with the Native Plains tipi which has a very different construction, structure, and use.
