The United States Department of Health and Human Services (HHS) is a Cabinet department of the federal government charged with protecting the health of Americans and providing essential human services. Its stated mission emphasizes improving health, safety, and well-being; the department sets national priorities, issues guidance and regulations, and supports public health, medical research, and social programs. The department’s work ranges from disease prevention and food and drug oversight to administering health coverage programs and supporting vulnerable populations.

Organization and major components

HHS is organized into an Office of the Secretary and a number of operating divisions and agencies that specialize in different areas. Among the best known are:

  • Centers for Disease Control and Prevention (CDC) — public health surveillance and disease prevention.
  • Food and Drug Administration (FDA) — regulation of foods, drugs, medical devices and biologics.
  • National Institutes of Health (NIH) — biomedical and behavioral research.
  • Centers for Medicare & Medicaid Services (CMS) — administration of major federal health insurance programs.
  • Administration for Children and Families (ACF) and Administration for Community Living (ACL) — grants and services for families, children, older adults and people with disabilities.
  • Substance Abuse and Mental Health Services Administration (SAMHSA) and Indian Health Service (IHS) — targeted health and behavioral health services.

History and development

The department traces its roots to mid‑20th century federal reorganizations that consolidated health and social programs. In its current form HHS succeeded an earlier department when education functions were separated into a distinct agency in the late 1970s. Since then HHS has expanded and adapted to new scientific developments, public health challenges and changes in social policy. Its activities often evolve in response to epidemics, demographic shifts and federal legislation.

HHS operates primarily from Washington, D.C., and works closely with state, tribal and local partners to implement programs. The department is led by the Secretary of Health and Human Services, a Cabinet official; the Surgeon General serves as a national public health spokesperson. HHS also houses offices that enforce civil rights protections, oversee grants and manage preparedness for public health emergencies.

Functions, importance and examples

Key functions of HHS include funding and conducting medical research, regulating health products and services, issuing public health guidance, and administering or overseeing programs such as Medicare and Medicaid. It provides grants to universities, health centers and community organizations, supplies technical assistance for public health systems, and coordinates federal responses to health crises. HHS’s regulatory and research activities influence clinical practice, industry standards and consumer safety.

Notable distinctions: HHS is a Cabinet-level department focused primarily on health and human services rather than education or labor; many of its programs operate through partnerships with state and local governments, reflecting a shared federal–state implementation model. Its agencies play leading roles in research, regulation and emergency response, making HHS central to national health policy and public welfare.
