The Walter Reed National Military Medical Center ('WRNMMC), formerly known as the National Naval Medical Center and colloquially referred to as the Bethesda Naval Hospital Bethesda, Walter Reed, or Navy Med, is a tri-service military medical center located in the community of Bethesda, Maryland, near the headquarters of the National Institutes of Health. It is one of the most prominent U.S. military medical centers in the Washington, D.C. metropolitan area and the United States, having served numerous U.S. presidents since the 20th century.
In 2011, the Walter Reed Army Medical Center (WRAMC), named after yellow fever researcher Walter Reed, was combined with the National Naval Medical Center to form the tri-service Walter Reed National Military Medical Center.
