Whatcom County is a county located in the northwestern corner of the U.S. state of Washington, bordered by the Lower Mainland of the Canadian province of British Columbia to the north, Okanogan County to the east, Skagit County to the south, San Juan County across Rosario Strait to the southwest, and the Strait of Georgia to the west. Its county seat and largest population center is the coastal city of Bellingham. Whatcom County is coterminous with the Bellingham Metropolitan Statistical Area. As of the 2020 census, the county's population was 226,847.

The Whatcom County area has had known human habitation for at least twelve millennia. At least three aboriginal tribes have been identified in the area: Lummi (San Juan Islands, between Point Whitehorn and Chuckanut Bay), Nooksack (between Lynden and Maple Falls) and Semiahmoo (the northern portion, near Blaine). This area was part of the Oregon Country at the start of the nineteenth century, inhabited both by fur prospectors from Canada and Americans seeking land for agricultural and mineral-extraction opportunities. Unable to resolve which country should control this vast area, the Treaty of 1818 provided for joint control. In 1827 the Hudson's Bay Company established Fort Langley near present Lynden. By 1843, the Provisional Government of Oregon had been established, although at first there were questions as to its authority and extent.

Where anything here differs from what Whatcom County or the Washington Secretary of State publishes, they are right and this page is not.
