The Fergus Falls Regional Treatment Center is a former hospital located in Fergus Falls, Minnesota. It was built in the Kirkbride Plan style and first opened to patients in 1890. Over the next century it operated as one of the state's main hospitals for the mentally ill and also worked with people with developmental disabilities and chemical dependency issues. It was added to the National Register of Historic Places in 1986. The hospital closed in 2007. Various proposals have been made to repurpose the site and buildings since its closure.
