In the Latter Day Saint movement, the term ordinance is used to refer to sacred rites and ceremonies that have spiritual and symbolic meanings and act as a means of conveying divine grace. Ordinances are physical acts which signify or symbolize an underlying spiritual act; for some ordinances, the spiritual act is the finalization of a covenant between the ordinance recipient and God.

Ordinances are usually performed by the authority of the LDS priesthood and in the name of Jesus Christ. The use of the term "ordinance" in LDS parlance is distinct from the use of the term in other branches of Christian tradition, where "ordinance (Christian)" is often used to imply that the act is merely symbolic and does not convey grace. LDS use of the term "ordinance" carries the same meaning as the term "sacrament" as used by other Christian denominations. Community of Christ-derived denominations of the Latter Day Saint movement also tend to refer to "sacraments" rather than "ordinances".

Some ordinances—such as baptism, confirmation and the sacrament of the Lord's Supper—are similar to those practiced by other Christian denominations. Other Latter Day Saint ordinances—including the endowment and sealings—are unique and usually performed within a Latter Day Saint temple.
