The NIH headquarters, known as the “NIH campus” to the local community, are located in Bethesda, Maryland. Administrative and program operations facilities are also located in off-campus buildings in the surrounding area. NIH scientists conduct their research in laboratories located on the main campus, and in several field units across the country and abroad.

The NIH campus is located in Bethesda, Maryland, just 10 miles from the center of Washington, DC.

The NIH implements security measures to ensure the safety of patients, employees, guests, and facilities.

Visitor parking is extremely difficult to find at NIH, so if at all possible, take public transportation.

Services are provided on the NIH campus and to off-campus facilities for employees, patients, and visitors.

We welcome visitors of all ages from across the United States and around the world.
