Northport is a town in Stevens County, Washington, United States. The population was 295 at the 2010 census.
Northport was given its name since it was once the northernmost town on the Spokane Falls and Northern Railway. It was officially incorporated on June 1, 1898 but has a history stretching back to the 1880s when it was a port and shipbuilding center for steamboat services running northwards into British Columbia during construction of the Canadian Pacific Railway, related to its location at a stretch of the Columbia known as the Little Dalles, a rapids and narrows that was a barrier to navigation and which also was an alternate name for Northport itself.
