USS Washtenaw County (LST-1166) was a Terrebonne Parish-class tank landing ship in commission in the United States Navy from 1953 to 1973. Named for Washtenaw County, Michigan, she was the only U.S. Navy vessel to bear the name. It is currently derelict. In October 2008, it was reported to be at the southeastern tip of Lord Island on the Columbia River in Rainier, Oregon at 46°07′18″ N 123°00′51″ W next to the Oregon shoreline. It is listed as a derelict vessel by the interagency Derelict Vessel Task Force, and has suffered damage from vandalism and looting between 2005 and 2008. While some had hoped to restore the ship as a museum ship, there is no funding or plan to do so.
