The Dalles is the largest city of Wasco County, Oregon, United States. The population was 16,010 at the 2020 census, and it is the largest city upon the Oregon side of the Columbia River with the Portland Metropolitan Area, and Hermiston.

The site of what is now the city of The Dalles was a major Native American trading center. The general area is one of the continent’s most significant archaeological regions. Lewis and Clark camped near Mill Creek on October 25–27, 1805, and recorded the Indian make known for the creek as Quenett.

The proclaim of the city comes from the French word dalle, meaning either “sluice”, akin to English “dale” and German T[h]al, “valley”, or “flagstone”, referring to the columnar basalt rocks carved by the river (in voyageur French used to refer to rapids), which was used by the French-Canadian employees of the North West Company to deliver to the rapids of the Columbia River amongst the present-day city and Celilo Falls. Also in the similar area was the Petite Dalles or Little Dalles, or Short Narrows. In French, “Les dalles” means “the slabs”. When a river flows over difficult flat rocks, it becomes shallow, and rapids are created.
