The Immortal Alamo is an American silent film released on May 25, 1911. The Immortal Alamo is the earliest film version of the events surrounding the 1836 Battle of the Alamo. The film was directed by William F. Haddock and produced by Gaston Méliès. The film's cast included Francis Ford, Edith Storey, William A. Carroll, and one hundred cadets from the Peacock Military Academy. The film was said to be 10 minutes in length and focused on the formula of "pretty girl, shy hero, and a villain" during the battle.

The film has been noted as historically inaccurate in its plot, but that it tries for accuracy in its setting. Reviews of the film were mixed and C. H. Claudy's criticism of the film is a striking contemporary account of the film's depiction. No known copies of the film exist today, and it is considered to be a lost film.
