Where the Buffalo Roam is a 1980 American semi-biographical comedy film which loosely depicts author Hunter S. Thompson's rise to fame in the 1970s and his relationship with Chicano attorney and activist Oscar "Zeta" Acosta. The film was produced and directed by Art Linson. Bill Murray portrayed Thompson and Peter Boyle portrayed Acosta, who is referred to in the film as Carl Lazlo, Esq. A number of other names, places, and details of Thompson's life are also changed.

Thompson's eulogy for Acosta ("The Banshee Screams for Buffalo Meat", published in the December 1977 issue of Rolling Stone) served as the nominal basis of the film, although screenwriter John Kaye drew from several other works, including Fear and Loathing on the Campaign Trail '72 and various pieces included in The Great Shark Hunt and Fear and Loathing in Las Vegas. Thompson was credited as an executive consultant on the film.
