Newel Kimball Whitney (February 5, 1795 – 24 September 1850) (first name sometimes found as Newell) was a prominent leader of The Church of Jesus Christ of Latter-day Saints (LDS Church) and an American businessman. He served as Bishop of Kirtland, Ohio, Far West, Missouri, and Nauvoo, Illinois. He also served as the second Presiding Bishop of the Church from 1847 until his death. He died in 1850 of pleurisy.
Whitney was the owner of a home-based store in Kirtland that was Mormonism's first "bishop's storehouse", known as the Newel K. Whitney Store. The building was also used by Church founder and president Joseph Smith, Jr. as a home and office. Smith received approximately 20 revelations in the store building and used one of its rooms as a meeting place of the School of the Prophets.
