"Out of the Silent Planet" is the debut studio album by the American rock band King's X, released in 1988. The title of the album is derived from a book by C. S. Lewis, an author favored by band members Ty Tabor and Jerry Gaskill. The first track of the follow-up album Gretchen Goes to Nebraska also bears the title "Out of the Silent Planet." The cover art features the skyline of Houston with the southern outline of the state of Texas.
The album received widespread acclaim from music contemporaries. Pantera bassist Rex Brown recalled that he and Dimebag Darrell were deeply impressed by the album. Brown noted that Dimebag called him to talk about King's X, and they listened to the album repeatedly on a long road trip. They found the sound they had been searching for in that record.
