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

The Twelve were designated to be a body of "traveling councillors" with jurisdiction outside areas where the church was formally organized (areas of the world outside of Zion or its outlying Stakes). The Twelve were designated as being equal in authority to the First Presidency, the Seventy, the standing presiding high council, and the High Councils of the various stakes.After the death of Joseph Smith in 1844, permanent schisms formed in the movement, resulting in the formation of various churches, many of which retained some version of the Quorum of the Twelve.
