The Alaska Mental Health Enabling Act of 1956 was an Act of Congress passed to improve mental health care in the United States territory of Alaska. Introduced in the House of Representatives by Alaska Congressional Delegate Bob Bartlett in January 1956, it became the focus of a major political controversy. The legislation was opposed by a variety of far-right, anti-Communist and fringe religious groups, prompting what was said to have been the biggest political controversy seen on Capitol Hill since the early 1940s. Prominent opponents nicknamed it the "Siberia Bill" and 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. With the sponsorship of the conservative Republican senator Barry Goldwater, a modified version of the Act was approved unanimously by the United States Senate in July 1956 after only ten minutes of debate.
