The Latter Day Saint movement is a religious movement within Christianity that arose during the Second Great Awakening in the early 19th century and that led to the set of doctrines, practices, and cultures called Mormonism, and to the existence of numerous Latter Day Saint churches. Its history is characterized by intense controversy and persecution in reaction to some of the movement's doctrines and practices and their relationship to mainstream Christianity (see Mormonism and Christianity). The purpose of this article is to give an overview of the different groups, beliefs, and denominations that began with the influence of Joseph Smith.

The founder of the Latter Day Saint movement was Joseph Smith, who was raised in the burned-over district of Upstate New York. Smith stated that, in response to prayer, he saw God the Father and Jesus Christ, as well as angels and other visions. This eventually led him to a restoration of Christian doctrine that, he said, was lost after the early Christian apostles were killed. In addition, several early leaders made marked doctrinal and leadership contributions to the movement, including Oliver Cowdery, Sidney Rigdon, and Brigham Young. Modern-day revelation from God continues to be a principal belief of the Mormon faith.

Mormon history as an academic field is called Mormon studies.
