The Post is a 2017 American political thriller film about The Washington Post and the publication of the Pentagon Papers. It was directed and produced by Steven Spielberg, and written by Liz Hannah and Josh Singer. It stars Meryl Streep as Katharine Graham, the publisher of the Washington Post, and Tom Hanks as Ben Bradlee, the longtime executive editor of The Washington Post, with Sarah Paulson, Bob Odenkirk, Tracy Letts, Bradley Whitford, David Cross, Bruce Greenwood, Carrie Coon, Alison Brie, and Matthew Rhys in supporting roles.

The Pentagon Papers, officially titled The History of U.S. Decision-Making in Vietnam, 1945–1968, is a United States Department of Defense history of the United States' political and military involvement in Vietnam from 1945 to 1968. Released by Daniel Ellsberg, who had worked on the study, they were first brought to the attention of the public on the front page of The New York Times in 1971. A 1996 article in The New York Times said that the Pentagon Papers had demonstrated, among other things, that Lyndon B. Johnson's administration had "systematically lied, not only to the public but also to Congress."
