In the Latter Day Saint movement, the Quorum of the Twelve is one of the governing bodies of the church hierarchy organized by the movement's founder Joseph Smith and patterned after the Apostles of Jesus. Members are called Apostles, with a special calling to be evangelistic ambassadors to the world.

The Latter Day Saint movement is the collection of independent church groups that trace their origins to a Christian Restorationist movement founded by Joseph Smith in the late 1820s.
