Celilo Falls was a tribal fishing area on the Columbia River, just east of the Cascade Mountains, on what is today the border between the U.S. states of Oregon and Washington. The name refers to a series of cascades and waterfalls on the river, as well as to the native settlements and trading villages that existed there in various configurations for 15,000 years. Celilo was the oldest continuously inhabited community on the North American continent until 1957, when the falls and nearby settlements were submerged by the construction of The Dalles Dam. In 2019, there were calls by tribal leaders to restore the falls.

Nez Perce, also spelled Nez Percé or called nimipuutímt, is a Sahaptian language related to the several dialects of Sahaptin. Nez Perce comes from the French phrase nez percé, "pierced nose"; however, Nez Perce, who call themselves nimiipuu, meaning "the people", did not pierce their noses. This misnomer may have occurred as a result of confusion on the part of the French, as it was surrounding tribes who did so.

Umatilla is a variety of Southern Sahaptin, part of the Sahaptian subfamily of the Plateau Penutian group. It was spoken during late aboriginal times along the Columbia River and is therefore also called Columbia River Sahaptin. It is currently spoken as a first language by a few dozen elders and some adults in the Umatilla Reservation in Oregon. Some sources say that Umatilla is derived from imatilám-hlama: hlama means 'those living at' or 'people of' and there is an ongoing debate about the meaning of imatilám, but it is said to be an island in the Columbia River. B. Rigsby and N. Rude mention the village of ímatalam that was situated at the mouth of the Umatilla River and where the language was spoken.
