Cimarron is a 1931 Pre-Code film directed by Wesley Ruggles and based on the Edna Ferber novel Cimarron.

Despite America being in the depths of the Depression, RKO immediately prepared for a big-budget picture, investing more than $1.5 million into Ferber's novel Cimarron. Director Wesley Ruggles would direct stars Richard Dix and Irene Dunne with a script written by Howard Estabrook. Filming began in the summer of 1930 at the Jasmin Quinn Ranch outside of Los Angeles, California. The film was a massive production, especially the land rush scenes, which recalled the epic scenes of Intolerance some fifteen years earlier. More than 5,000 extras, twenty-eight cameramen, and numerous camera assistants and photographers were used to capture scenes of wagons racing across grassy hills and prairie. Cinematographer Edward Cronjager spent overtime planning out every scene in accordance to Ferber's descriptions.

Like many of the movies of its time, Cimarron has been perceived to represent blacks, Jews, and American Indians in a stereotypical fashion. However, Cimarron is notable for the conflicting attitudes of the principal characters towards non-whites. Sabra Cravat refers to American Indians as "dirty, filthy savages" and refuses to allow her son to accept a gift of feathered headgear from an Indian. Her husband, Yancey Cravat, has a more sympathetic view, acknowledging that the Indians in the back of the church are not expected to give a monetary contribution to the purchase of a white man's church organ as they have had their land stolen by the white men.
