The National Museum of American History: Kenneth E. Behring Center is a historical museum in Washington, D.C. It collects, preserves, and displays the heritage of the United States in the areas of social, political, cultural, scientific, and military history. Among the items on display is the original Star-Spangled Banner. The museum is part of the Smithsonian Institution and located on the National Mall at 14th Street and Constitution Avenue NW in Washington, D.C.

The Star-Spangled Banner, or the Great Garrison Flag, was the garrison flag that flew over Fort McHenry in Baltimore Harbor during the naval portion of the Battle of Baltimore during the War of 1812. It is on exhibit at the National Museum of American History, Smithsonian Institution. Seeing the flag flying over Fort McHenry on the morning of September 14, 1814, after the battle ended, Francis Scott Key was inspired to write the poem "Defence of Fort M'Henry". These words were written by Key and set to the tune of "To Anacreon in Heaven", a popular song at the time, by John Stafford Smith. In 1931 the song became the national anthem of the United States.
