The Washington Post is an American daily newspaper. It is the most widely circulated newspaper published in Washington, D.C., and was founded on December 6, 1877, making it the area's oldest extant newspaper. Its slogan is "Democracy Dies in Darkness".

Located in the capital city of the United States, the newspaper has a particular emphasis on national politics. Daily editions are printed for the District of Columbia, Maryland, and Virginia. The newspaper is published as a broadsheet, with photographs printed both in color and in black and white. 

The newspaper has won 47 Pulitzer Prizes. This includes six separate Pulitzers awarded in 2008, the second-highest number ever awarded to a single newspaper in one year, second only to The New York Times' seven awards in 2002. Post journalists have also received 18 Nieman Fellowships and 368 White House News Photographers Association awards. In the early 1970s, in the best-known episode in the newspaper's history, reporters Bob Woodward and Carl Bernstein led the American press' investigation into what became known as the Watergate scandal; reporting in the newspaper greatly contributed to the resignation of President Richard Nixon. In years since, its investigations have led to increased review of the Walter Reed Army Medical Center.
