Reportedly haunted locations in the District of Columbia

There are a number of reportedly haunted locations in Washington, D.C. The city is the capital of the United States, and was founded (pursuant to an Act of Congress) on July 16, 1790. The City of Washington was originally a separate municipality within the Territory of Columbia until an act of Congress in 1871 effectively merged George Town, the City of Washington, and the Territory of Columbia into a single entity called the District of Columbia. Washington, D.C., has been the site of military battles, deadly duels, assassinations, untimely deaths, and associated tragedies.

Washington's haunted history is so well known that some of its haunted locations were featured in a 2006 documentary, America's Haunted Houses, on the A&E cable network. Novelist Dan Brown mentioned them prominently in his 2009 novel, The Lost Symbol. Notable purportedly haunted locations include the United States Capitol, Capitol Hill, the White House, Lafayette Square and nearby buildings, Independence Avenue SW, The Octagon House, Chinatown, the National Theatre, Hay–Adams Hotel, Woodrow Wilson House, Omni Shoreham Hotel, and many others.

The United States Capitol is reputedly haunted by many past representatives of the United States House of Representatives and government officials, officers who served during the American Revolutionary War, workers who died during its construction and a "demon black cat" that is said to make appearances just before national tragedies or changes in Presidential administration. A very high number of apparitions of deceased American presidents have been reported in the White House, the most famous of which is Abraham Lincoln, reported even by later presidents such as Harry S. Truman, and apparitions of presidents Thomas Jefferson, Andrew Jackson, and John Tyler have all been witnessed, as have the spirits of many First Ladies.
