David Allan Bednar (born June 15, 1952) was sustained on October 2, 2004 as a member of the Quorum of the Twelve Apostles of The Church of Jesus Christ of Latter-day Saints, the youngest man named to that body since Dallin H. Oaks in 1984. He was ordained on October 7,2004 by President Gordon B. Hinckley. He fills the vacancy occasioned by the death of Elder David B. Haight in July 2004.

He was also the first Apostle since Oaks not to have served previously as a General Authority of the Church. As succession to the presidency is by seniority as an Apostle and Elder Bednar is more than eleven years younger than any of the others, there is some speculation that he may become President of the Church at a future date.

Formerly a church stake president and regional representative in Arkansas while he was an associate dean at the University of Arkansas, in 1997 Elder Bednar became president of what was then Ricks College and is now Brigham Young University-Idaho. At the same time, he was named to the Fifth Quorum of the Seventy.
