The Alaska Mental Health Enabling Act of 1956 (Public Law 84-830) was an Act of Congress passed to improve mental health care in the United States territory of Alaska. It became the focus of a major political controversy after opponents nicknamed it the "Siberia Bill" and denounced it as being part of a communist plot to hospitalize and brainwash Americans. Campaigners asserted that it was part of an international Jewish, Roman Catholic or psychiatric conspiracy intended to establish United Nations-run concentration camps in the United States.
