The National Museum of American History is a Smithsonian museum on the National Mall in Washington, D.C., that documents U.S. political, cultural, scientific and social history; the building opened to the public in 1964. The collection spans a wide range of artifacts from political objects to everyday material culture and iconic national items.

Exhibit highlights include large, conservation-monitored displays that interpret national symbols, political history and technological change. Galleries rotate objects from a collection that covers multiple centuries, allowing visitors to see both long-term artifacts and temporary special exhibitions.

The museum was established in the mid-20th century and has undergone periodic renovations and reorganization of its galleries to improve preservation and visitor interpretation. It is part of the Smithsonian Institution and collaborates on loans and traveling exhibitions.

The museum sits on the National Mall in Washington, D.C., within a short walk of other Smithsonian museums and national monuments, making it a common stop on Mall itineraries.

  • Enter from the National Mall/Constitution Avenue side to immediately access the main American history galleries and save time walking across the Mall between sites.
  • Use the museum's online map and exhibit highlights to prioritize small, popular artifacts that get crowded quickly - plan a route so you see high-demand items first and leave broader galleries for later in the day.
