Spokane Valley is a city in Spokane County, Washington, United States, and the largest suburb of Spokane. It is located east of Spokane, west of Coeur d'Alene, Idaho and surrounds the city of Millwood on three sides.
The city incorporated as the City of Spokane Valley on March 31, 2003. The Washington State Office of Financial Management estimates the city’s population as 100,810 as of 2019. Spokane Valley is named after the valley of the Spokane River, in which it is located. Before becoming an incorporated city, the area was and still is referred to as "The Valley" by residents of the Spokane–Coeur d'Alene area. The city was formed from a merger of the unincorporated census-designated places (CDPs) of Dishman, Opportunity, Trentwood, Veradale, as well as the western section of the CDP of Greenacres. Unlike the other five towns, Millwood avoided becoming part of Spokane Valley by incorporating itself in 1927; although, it is part of the Greater Spokane Valley Chamber of Commerce. For thousands of years, the Spokane Valley area was populated by members of the Upper Band of the Interior Salish Indians, calling themselves “Sn-tutuul-i”, the meaning of which is not known.
