It is intended to be a complete list of the properties and districts on the National Register of Historic Places in Washington County, Minnesota, United States.

Many of the historic properties are associated with the timber industry, which began just after treaties with the Dakota and Ojibwe Indians were signed in 1837. The first sawmill in the state was established in Marine Mills (now Marine on St. Croix) in 1839. Other towns along the St. Croix River were associated with the lumber trade: Stillwater, Lakeland, and Point Douglas. Many of the houses in Stillwater are associated with wealthy lumbermen. Railroads and other industries also played a part in the development of the county.
Several of these properties are listed in the "Washington County Multiple Resource Area".[1]
