Wag the Dog is a 1997 American black comedy political satire film starring Dustin Hoffman and Robert De Niro. Produced and directed by Barry Levinson, the film centers on a spin doctor and a Hollywood producer who fabricate a war in Albania to distract voters from a presidential sex scandal. The screenplay by Hilary Henkin and David Mamet was loosely adapted from Larry Beinhart's 1993 novel, American Hero.

The title of the film comes from the English-language idiom "the tail wagging the dog", used to indicate attention that is purposely being diverted from something of greater importance to something of lesser.

Wag the Dog was released one month before the news broke of the Clinton–Lewinsky scandal and the bombing of the Al-Shifa pharmaceutical factory in Sudan by the Clinton administration in August 1998, which prompted the media to draw comparisons between the film and reality. The comparison was also made in December 1998, when the administration initiated a bombing campaign of Iraq during Clinton's impeachment trial for the Clinton–Lewinsky scandal. It was made again in spring 1999, when the administration intervened in the Kosovo War and initiated a bombing campaign against Yugoslavia, which, coincidentally, bordered Albania and contained ethnic Albanians.

The film grossed $64.3 million on a $15 million budget, and was well received by critics, who praised the direction, performances, themes and humor. Hoffman received a nomination for the Academy Award for Best Actor for his performance, and screenwriters David Mamet and Hilary Henkin were both nominated for Best Adapted Screenplay.
