Snohomish County (/snoʊˈhoʊmɪʃ/) is a county located in the U.S. state of Washington. With a population of 827,957 as of the 2020 census, it is the third-most populous county in Washington, after nearby King and Pierce counties, and the 72nd-most populous in the United States. The county seat and largest city is Everett. The county forms part of the Seattle metropolitan area, which also includes King and Pierce counties to the south.
The county's western portion, facing Puget Sound and other inland waters of the Salish Sea, is home to the majority of its population and major cities. The eastern portion is rugged and includes portions of the Cascade Range, with few settlements along major rivers and most of it designated as part of the Mount Baker–Snoqualmie National Forest. Snohomish County is bound to the north by Skagit County, to the east by Chelan County, to the south by King County, and to the west by Kitsap and Island counties.
