The Washington Post (also known as the Post and, informally, WaPo) is an American daily newspaper published in Washington, D.C. It is the most widely circulated newspaper within the Washington metropolitan area.

The Post was founded in 1877. In its early years, it went through several owners and struggled both financially and editorially. Financier Eugene Meyer purchased it out of bankruptcy in 1933 and revived its health and reputation, work continued by his successors Katharine and Phil Graham (Meyer's daughter and son-in-law), who bought out several rival publications. The Post's 1971 printing of the Pentagon Papers helped spur opposition to the Vietnam War. Reporters Bob Woodward and Carl Bernstein broke the story about a break-in at the Democratic National Headquarters at the Watergate in Washington D.C. and the cover up that followed. The Watergate scandal resulted in the 1974 resignation of President Richard Nixon. In October 2013, the Graham family sold the newspaper to Nash Holdings, a holding company owned by Jeff Bezos, for $250 million.

As of 2020 the newspaper had won the Pulitzer Prize 65 times for its work, the second-most of any publication (after The New York Times). It is considered a newspaper of record in the U.S. Post journalists have received 18 Nieman Fellowships and 368 White House News Photographers Association awards. The paper is one of the few remaining American newspapers to operate foreign bureaus.
