The Missouri Traveler is a 1958 American coming-of-age period piece drama film directed by Jerry Hopper starring Brandon deWilde and Lee Marvin. It is based on the novel of the same name by John Burress. The cinematography was by Technicolor developer Winton C. Hoch with harmonica and banjo score by Jack Marshall of The Munsters fame. The feature was distributed by the Buena Vista Corporation subsidiary of Walt Disney Productions, but the film did not carry the "Disney" trademark.
