The National Archives Mid Atlantic Region is one of 14 Regional programs of the nation's official record keeper, the National Archives and Records Administration.  These Regional programs, together with the Presidential Libraries and the Washington, D.C.-based programs, preserve and make accessible the historically significant evidence of America's national experience from the first Continental Congress to modern times. In trust for the American people and open to the public, the National Archives enables every citizen to inspect for themselves the record evidence of the American democracy.

The Mid-Atlantic Region holds over 110 million individual historicaly significant records, in paper and other media, for over 80 federal agencies and the district courts in the states of Delaware, Maryland, Pennsylvania, Virginia and West Virginia, as well as copies of selected microfilmed records for the entire country. As Philadelphia was the nation's capital from 1790 through 1800, these regional records are singularly important in understanding the development of the federal government, as the Constitution evolved from parchment into a network of agencies and programs.  Court cases are among the richest holdings.  Holdings cover institutions such as the Philadelphia Navy Yard, the Merchant Marines, the National Park Service, NASA's Langley Research Center, the DuPont Company, Coca Cola, and Good Humor; subjects such as intellectual property (trademarks, copyrights and patents), treason, fugitive slaves, free speech, freedom of assembly, immigration and citizenship, numismatics, domestic and international trade, Civil War, and freedom of religion; and individuals from Patrick Henry, Robert Morris, Robert E. Lee through Thomas Edison, and Thurgood Marshall.

In support of NARA's strategic goal of civic literacy, the Mid Atlantic Regional supports several Teaching American History grant-funded projects, and National History Day.
