The term Latter-Day Saint is a religious term used to refer to members of The Church of Jesus Christ of Latter-day Saints, commonly known as the Mormon Church. The term is derived from the church's belief in a modern-day prophet and the restoration of the gospel of Jesus Christ. The term 'Mormon' is often used as a shorthand for Latter-day Saints, as it is derived from the Book of Mormon, which is a sacred text of the church.
