Badlands is a 1973 American neo-noir period crime drama film written, produced and directed by Terrence Malick, in his directorial debut.

The film also stars Warren Oates and Ramon Bieri. While the story is fictional, it is loosely based on the real-life murder spree of Charles Starkweather and his girlfriend, Caril Ann Fugate, in 1958.Badlands was released in 1973 to positive reviews from critics, who particularly praised its cinematography, soundtrack—which includes pieces by Carl Orff—and the lead performances. At the 28th British Academy Film Awards, Spacek was nominated for the Most Promising Newcomer to Leading Film Roles award, and at the San Sebastián International Film Festival, Sheen won the Best Actor award.

In 1993, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
