Dallin Harris Oaks (born August 12, 1932) is an American jurist, educator, and religious leader who since 2018 has been the First Counselor in the First Presidency of The Church of Jesus Christ of Latter-day Saints (LDS Church). He was called as a member of the church's Quorum of the Twelve Apostles in 1984. Currently, he is the second most senior apostle by years of service and is the President of the Quorum of the Twelve Apostles. However, consistent with long-established practice, due to Oaks serving in the First Presidency, M. Russell Ballard (third in seniority) currently serves as the quorum's acting president.
