La Bamba is a 1987 American biographical drama film written and directed by Luis Valdez. The film follows the life and short-lived musical career of American Chicano rock and roll star Ritchie Valens. The film stars Lou Diamond Phillips as Valens, Esai Morales, Rosanna DeSoto, Elizabeth Peña, Danielle von Zerneck and Joe Pantoliano. The film also covers the effect that Valens' career had on the lives of his half-brother Bob Morales, his girlfriend Donna Ludwig, and the rest of his family. The film is titled after a traditional Mexican folk song of the same name, which Valens transformed into a rock and roll rendition in 1958.

In 2017, La Bamba was included in the annual selection of 25 motion pictures added to the National Film Registry of the U.S. Library of Congress being deemed "culturally, historically, or aesthetically significant" and recommended for preservation.
