Medical Center station is a Washington Metro station in Bethesda, Maryland, United States. The island-platformed station was opened on August 25, 1984, and is operated by the Washington Metropolitan Area Transit Authority (WMATA). Providing service for the Red Line, the station serves the National Institutes of Health campus and the Walter Reed National Military Medical Center, and is located at Rockville Pike and South Drive. Since there is little retail in the area and no commuter parking lot, this station is used almost exclusively by employees and visitors to those two institutions.
