Dammasch State Hospital was a mental hospital, asylum, and educational center located in Wilsonville, Oregon, United States. Named for Dr. Ferdinand H. Dammasch, the hospital opened in 1961 and closed in 1995. After its closure, the former site was embroiled in local controversy as it was a proposed location for a women's prison, which angered local residents as the site is less than a mile from residential neighborhoods. The Dammasch building was demolished, and the Villebois housing development occupies its former site.
