Dangerous Liaisons is a 1988 American period romantic drama film directed by Stephen Frears from a screenplay by Christopher Hampton, based on his play Les liaisons dangereuses, which was itself adapted from the 18th-century French novel of the same name by Pierre Choderlos de Laclos. It stars Glenn Close, John Malkovich, Michelle Pfeiffer, Swoosie Kurtz, Mildred Natwick, Peter Capaldi, Keanu Reeves and Uma Thurman.

Dangerous Liaisons was released theatrically on December 16, 1988, by Warner Bros. It received generally positive reviews from critics with praise for Close's and Pfeiffer's performances and the screenplay, production values and costumes. Although it was a moderate commercial success grossing $34.7 million against its $14 million budget, it was cited as a box office disappointment. The film received seven nominations at the 61st Academy Awards, including for Best Picture and won three: Best Adapted Screenplay, Best Costume Design, and Best Production Design.
