Louisiana Story is a 1948 documentary film which shows the effects of industrialization from the viewpoint of a young boy. It was written by Frances H. Flaherty and Robert J. Flaherty, and directed by Robert J. Flaherty. Like Flaherty's other films, Louisiana Story is heavily fictionalized. The story deals with the installation of an oil drill in the Louisiana swamp, stressing the oil drill's peaceful and unproblematic coexistence with the surrounding nature. The film was in fact funded by an oil company.

It was nominated for an Academy Award for Best Writing, Motion Picture Story. The film has been deemed "culturally significant" by the Library of Congress and selected for preservation in the United States National Film Registry. Virgil Thomson won the Pulitzer Prize for Music in 1949 with his score for the film.
