The Palus are a Sahaptin tribe recognized in the Treaty of 1855 with the Yakamas, negotiated at the 1855 Walla Walla Council. A variant spelling is Palouse, which was the source of the name for the fertile prairie of Washington and Idaho. Today they are enrolled in the federally recognized Confederated Tribes and Bands of the Yakama Nation and are represented by the Colville Confederated Tribes.
