Walla Walla (/ˌwɒləˈwɒlə/ WOL-ə-WOL-ə), sometimes Waluulapam, are a Sahaptin indigenous people of the Northwest Plateau. The duplication in their name expresses the diminutive form. The name Walla Walla is translated several ways but most often as "many waters."
Many Walla Wallas live on the Confederated Tribes of the Umatilla Indian Reservation. The Walla Wallas share land and a governmental structure with the Cayuse and the Umatilla tribes as part of the Confederated Tribes of the Umatilla. The reservation is located in the area of Pendleton, Oregon, United States, near the Blue Mountains. Some Walla Wallas are also enrolled in the federally recognized Confederated Tribes and Bands of the Yakama Nation.
The people are a Sahaptin-speaking tribe that traditionally inhabited the interior Columbia River region of present-day northwestern United States. For centuries before the coming of European settlers, the Walla Wallas, consisting of three principal bands, occupied the territory along the Walla Walla River and along the confluence of the Snake and Columbia River rivers in a territory that is now part of northern Oregon and southeastern Washington state. From this zone, the Walla Walla followed a similar pattern of seasonal subsistence practices to that of the Yakama, Palouse, Umatilla, and Wanapum tribes.
