The Substance Abuse and Mental Health Services Administration (SAMHSA) is a branch of the U.S. Department of Health and Human Services. It is charged with improving the quality and availability of prevention, treatment, and rehabilitative services in order to reduce illness, death, disability, and cost to society resulting from substance abuse and mental illnesses. The Administrator of SAMHSA reports directly to the Secretary of the U.S. Department of Health and Human Services. SAMHSA's headquarters building is located in Rockville, Maryland.

SAMHSA was established in 1992 by Congress as part of a reorganization of the Federal administration of mental health services; the Alcohol, Drug Abuse, and Mental Health Administration (ADAMHA) was abolished and its service components were transferred to the newly-organized SAMHSA.

Congress directed SAMHSA to target effectively substance abuse and mental health services to the people most in need and to translate research in these areas more effectively and rapidly into the general health care system.
