David O. McKay, American religious leader, 9th President of The Church of Jesus Christ of Latter-day Saints (died 1970)

David Oman McKay was an American religious leader and educator who served as the ninth president of the Church of Jesus Christ of Latter-day Saints from 1951 until his death in 1970. Ordained an apostle and member of the Quorum of the Twelve Apostles in 1906, McKay was an active general authority for nearly 64 years, longer than anyone else in LDS Church history.

The president of the church is the highest office of the Church of Jesus Christ of Latter-day Saints. It was the office originally held by Joseph Smith, the church's founder. The church's president is its leader and is head of the First Presidency, its highest governing body. Latter-day Saints consider the president of the church to be a "prophet, seer, and revelator" and refer to him as "the Prophet", a title that was originally given to Smith. When the name of the president is used by adherents, it is usually prefaced by the title "President". Russell M. Nelson has been the president since January 14, 2018.
