Walla Walla is a Sahaptin Native American tribe of the northwestern United States. The reduplication of the word expresses the diminutive form. The name "Walla Walla" is translated several ways but most often as "many waters." Many Walla Walla live on the Confederated Tribes of the Umatilla Indian Reservation. The Walla Walla 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 Pendleton, Oregon, United States, near the Blue Mountains. The people are a Sahaptin-speaking tribe which traditionally inhabited the Columbia River region of the northwestern United States. The Walla Walla occupied the territory along the Walla Walla River and along the junction of the Snake and Columbia Rivers in a territory that is now part of northern Oregon and southeastern Washington state in the United States before the coming of white settlers.
