The Katahdin Iron Works is a Maine state historic site located in the unorganized township of the same name. It is the site of an ironworks which operated from 1845 to 1890. In addition to the kilns of the ironworks (of which only one survives), the community was served by a railroad and had a 100-room hotel. The site was listed on the National Register of Historic Places in 1969.
The state's property contains Gulf Hagas, a canyon on the West Branch of the Pleasant River that is a National Natural Landmark. About a mile and a half downriver is another national landmark, "The Hermitage", a roughly 35-acre (14 ha) grove of large Eastern White Pine trees that is preserved by The Nature Conservancy. In 2003, the Appalachian Mountain Club acquired a 37,000-acre (15,000 ha) property upriver from Gulf Hagas that it named Katahdin Iron Works.
