A temple garment, also referred to as garments, the garment of the holy priesthood, or Mormon underwear, is a type of underwear worn by adherents of the Latter Day Saint movement after they have taken part in the endowment ceremony. Garments are required for any individual who previously participated in the endowment ceremony to enter a temple. The undergarments are viewed as a symbolic reminder of the covenants made in temple ceremonies and are seen as a symbolic and/or literal source of protection from the evils of the world.

In the Church of Jesus Christ of Latter-day Saints, a temple is a building dedicated to be a House of the Lord. Temples are considered by church members to be the most sacred structures on earth.
