Office of the Secretary of the Interior is the executive leadership office that directs the United States Department of the Interior and coordinates federal stewardship of public lands, natural resources, and obligations to Native American tribes. The office advises the President of the United States and implements statutes enacted by the United States Congress, while interacting with federal agencies, state governments, tribal nations, and international partners. It provides policy guidance to operational bureaus such as the Bureau of Land Management, National Park Service, U.S. Fish and Wildlife Service, Bureau of Indian Affairs, and Bureau of Ocean Energy Management.

Role and Responsibilities

The office sets policy for stewardship of the National Park System, oversight of public land management, and administration of Indian reservations and Alaska Native issues, coordinating with entities like the Environmental Protection Agency, United States Forest Service, Federal Emergency Management Agency, Department of Defense, and Department of Commerce. It provides leadership on resource extraction on federal land, interacting with the United States Geological Survey, Bureau of Reclamation, Office of Surface Mining Reclamation and Enforcement, and energy regulators including the Federal Energy Regulatory Commission. The office manages cultural resource protection in cooperation with the Smithsonian Institution, National Archives and Records Administration, Advisory Council on Historic Preservation, and National Trust for Historic Preservation, while engaging with United Nations Educational, Scientific and Cultural Organization conventions and international environmental agreements.

Established amid territorial expansion during the presidency of Zachary Taylor and congressional action by the Thirty-first United States Congress, the office evolved from early land policy shaped by events like the Louisiana Purchase, Mexican–American War, and the establishment of Yellowstone National Park. Secretaries such as Thomas Ewing, Alfred A. Cumming, John Eaton, Herbert Hoover (before presidency), Harold Ickes, Douglas McKay, and Stewart Udall influenced conservation policy alongside legislators including Stephen A. Douglas and activists like John Muir and Gifford Pinchot. The office adapted through eras defined by the Progressive Era, New Deal, Great Depression, World War II, Civil Rights Movement, and environmental milestones like the passage of the National Environmental Policy Act, the Endangered Species Act, and the Indian Self-Determination and Education Assistance Act.

The Secretary, assisted by the Deputy Secretary of the Interior, oversees principal offices including the Solicitor of the Department of the Interior, Assistant Secretary for Land and Minerals Management, Assistant Secretary for Fish and Wildlife and Parks, Assistant Secretary for Indian Affairs, and Assistant Secretary for Water and Science. The office commands bureaus such as the National Park Service, Bureau of Land Management, Bureau of Indian Affairs, United States Fish and Wildlife Service, Bureau of Reclamation, Office of Surface Mining Reclamation and Enforcement, and the United States Geological Survey. Staff roles include policy advisors, legal counsel interacting with the United States Department of Justice, congressional liaisons with House Committee on Natural Resources and Senate Committee on Energy and Natural Resources, and external affairs teams coordinating with the Association of American Indian Affairs, National Congress of American Indians, Outdoor Industry Association, and conservation NGOs like the Sierra Club, The Nature Conservancy, and Audubon Society.

Major programs directed by the office include the management of the National Park System, endangered species protection under the Endangered Species Act, water projects via the Bureau of Reclamation, energy leasing programs onshore and offshore with the Bureau of Ocean Energy Management and Bureau of Land Management, and urban conservation partnerships with entities like the National Park Foundation. Initiatives have addressed issues such as wildfire management coordination with the U.S. Forest Service and National Interagency Fire Center, restoration of ecosystems referenced in the Chesapeake Bay Program and Everglades restoration, tribal self-governance under the Indian Self-Determination and Education Assistance Act, and climate resilience aligned with international forums such as the United Nations Framework Convention on Climate Change.

The office exercises authority under statutes such as the Organic Act of 1916 for the National Park Service, the Federal Land Policy and Management Act of 1976, the Endangered Species Act, the National Environmental Policy Act, and the Indian Self-Determination and Education Assistance Act, and is subject to oversight from the United States Congress, the Government Accountability Office, the Office of Inspector General, and judicial review by federal courts. Its regulatory actions appear in the Code of Federal Regulations and are coordinated with regulatory agencies including the Environmental Protection Agency and the National Oceanic and Atmospheric Administration, with litigation and administrative proceedings handled through the United States Department of Justice and federal appellate courts.
