Woodinville is a city in King County, Washington, United States. The population was 10,938 at the 2010 census. It is part of the Seattle metropolitan area. There is also a much larger population with Woodinville mailing addresses in adjacent unincorporated areas of King (Cottage Lake) and Snohomish (Maltby) counties. Woodinville has waterfront parks on the Sammamish River, sweeping winery and brewery grounds, and densely wooded residential areas.
Prior to Anglo-American settlement, the Woodinville area was inhabited by the native Sammamish people.
In 1871, Ira Woodin and his wife Susan moved from Seattle and up the Sammamish River to build a cabin, log timber and farm cattle. A town gradually built up around the cabin, which served as its first school and Post Office, with Susan Woodin as Postmaster. Woodin and his son-in-law Thomas Sanders set up the first general store.
