Jerald Dee Tanner (June 1, 1938 – October 1, 2006) and Sandra McGee Tanner (born January 14, 1941) are American writers and researchers who publish archival and evidential materials about the history of The Church of Jesus Christ of Latter-day Saints (LDS Church). The Tanners founded the Utah Lighthouse Ministry (UTLM), whose stated mission is "to document problems with the claims of Mormonism and compare LDS doctrines with Christianity". Sandra Tanner continues to operate the ministry after Jerald's death in 2006.
