Sound of Freedom is a 2023 American Christian thriller film directed and co-written by Alejandro Monteverde, and starring Jim Caviezel, Mira Sorvino, and Bill Camp. Caviezel plays Tim Ballard, a former U.S. government agent who embarks on a mission to rescue children from sex traffickers in Colombia. It is produced by Eduardo Verástegui, who also plays a role in the film. The plot centers around Ballard's Operation Underground Railroad, an anti-sex trafficking organization. While the film is purportedly based on the life of Ballard, multiple investigative journalists have written about the real-life Ballard and O.U.R., pointing out that the events in the film bear little resemblance to reality.

The film was released on July 4, 2023, by Angel Studios, and was a sleeper hit, grossing $250 million against a $14.5 million budget to become one of the most successful independent films in history. It received mixed reviews from critics, while audience reception was highly positive. The film attracted considerable attention for its alleged connections to QAnon conspiracy theories, although Ballard and Monteverde refute the links, despite Ballard and Caviezel's belief in said theories.
