Spencer Woolley Kimball was an American religious leader who was the twelfth president of the Church of Jesus Christ of Latter-day Saints. The grandson of early Latter-day Saint apostle Heber C. Kimball, Kimball was born in Salt Lake City, Utah Territory. He spent most of his early life in Thatcher, Arizona, where his father, Andrew Kimball, farmed and served as the area's stake president. He served an LDS mission in Independence, Missouri, from 1914 to 1916, then worked for various banks in Arizona's Gila Valley as a clerk and bank teller. Kimball later co-founded a business selling bonds and insurance that, after weathering the Great Depression, became highly successful. Kimball served as a stake president in his hometown from 1938 until 1943, when he was called as a member of the Quorum of the Twelve Apostles.

The President of the Church is the highest office of the Church of Jesus Christ of Latter-day Saints. It was the office held by Joseph Smith, the church's founder. The church's president is its leader and the 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.
