Which building houses the National Park Service headquarters in Washington, D.C.?

The National Park Service headquarters is housed in the Main Interior Building in Washington, D.C.

The building is the headquarters of the U.S. Department of the Interior, the cabinet department that includes the National Park Service. It stands at 1849 C Street NW, several blocks southwest of the White House.

The National Park Service is headquartered there because it operates as a bureau within the Interior Department rather than as an independent cabinet agency. Its central offices coordinate policy, budgets, conservation science, visitor services, law enforcement, and park planning.

The Main Interior Building should not be confused with the White House, the U.S. Capitol, or the nearby Smithsonian museums. The National Park Service also maintains regional offices around the country, but Washington, D.C., remains its national administrative center.
