Deadwood is an unincorporated community in Lane County, Oregon, United States. It is located on Oregon Route 36, in the Oregon Coast Range. Deadwood was named after Deadwood Creek, a tributary of Lake Creek in the Siuslaw River basin. Deadwood Creek was so-named because of the dead timber snags next to its banks, which had resulted from a series of wildfires in the area. Deadwood post office was established in 1884.
