The 'Umatilla' are a Sahaptin-speaking Native American group living on the Umatilla Indian Reservation, who traditionally inhabited the Columbia Plateau region of the northwestern United States.
The Umatilla share land and a governmental structure with the Cayuse and the Walla Walla tribes as part of the Confederated Tribes of the Umatilla Indian Reservation. The reservation is located near Pendleton, Oregon near the Blue Mountains.
A number of places and geographic features have been named after the tribe, such as the Umatilla River, Umatilla County, and Umatilla National Forest. McNary Dam was almost named Umatilla Dam. The impoundment of the Columbia River behind the next dam downriver, John Day Dam, is called Lake Umatilla.
