Mormon studies is the interdisciplinary academic study of the beliefs, practices, history and culture of individuals and denominations belonging to the Latter Day Saint movement, a religious movement associated with the Book of Mormon, though not all churches and members of the Latter Day Saint movement identify with the terms Mormon or Mormonism. Denominations of the Latter Day Saint movement include the Church of Jesus Christ of Latter-day Saints, by far the largest, as well as the Community of Christ (CoC) and other smaller groups, include some categorized under the umbrella term Mormon fundamentalism.

Mormons are a religious and cultural group related to Mormonism, the principal branch of the Latter Day Saint movement started by Joseph Smith in upstate New York during the 1820s. After Smith's death in 1844, the movement split into several groups following different leaders; the majority followed Brigham Young, while smaller groups followed Joseph Smith III, Sidney Rigdon, and James Strang. Most of these smaller groups eventually merged into the Community of Christ, and the term Mormon typically refers to members of the Church of Jesus Christ of Latter-day Saints, as today, this branch is far larger than all the others combined. People who identify as Mormons may also be independently religious, secular, and non-practicing or belong to other denominations. Since 2018, the LDS Church has emphasized a desire for its members be referred to as "members of The Church of Jesus Christ of Latter-day Saints", or more simply as "Latter-day Saints".
