The Vanishing Outpost is a 1951 American Western film produced and directed by Ron Ormond and starring Lash LaRue and Al "Fuzzy" St. John. It is the tenth of LaRue's films for Ormond's Western Adventures Productions Inc., the fourth to be released by Howco and Ormond's second film as director. The screenplay is credited to Ormond's wife June Carr and Maurice Tombragel. The film is composed mostly of footage from the previous Ormond-LaRue Westerns Son of Billy the Kid (1949), Mark of the Lash (1948), Outlaw Country (1949) and Son of a Bad Man (1949). Despite the title, no outposts are involved in the plot.
