Corianton: A Story of Unholy Love is a 1931 American drama film based on the story of Corianton, the son of the prophet Alma in the Book of Mormon. Corianton appears only briefly in three ages in the Book of Mormon. However, as scholars Randy Astle and Gideon Burton point out, his story is one of the only stories in the Book of Mormon "with any sex in it", which has made it a popular subject of Book of Mormon-themed fiction and drama for more than a century.

Before the film was made, the Corianton story had been the basis of two novellas (including one by an LDS general authority), one traveling stage play, and one Broadway play with music by a Broadway composer. The film brought in elements from all of these previous works but was ultimately unsuccessful and resulted in multiple lawsuits against the producers by their financial backers. In 2009, the film was restored by archivists at Brigham Young University.
