Mark Edward Petersen (November 7, 1900 – January 11, 1984) was an American news editor and religious leader. He was born in Salt Lake City, Utah. He served as a member of the Quorum of the Twelve Apostles of the Church of Jesus Christ of Latter-day Saints (LDS Church) from 1944 until his death. He became managing editor of the church-owned Deseret News in 1935 and then editor in 1941. He filled the vacancy in the Quorum caused by the excommunication of Richard R. Lyman.
