John Smith (nephew of Joseph Smith)

John Smith (September 22, 1832 – November 6, 1911), was the fifth Presiding Patriarch of The Church of Jesus Christ of Latter-day Saints (LDS Church). His father was Hyrum Smith, the older brother of Joseph Smith, the founder of Mormonism.

John was born in Kirtland, Ohio, to Hyrum Smith and his first wife, Jerusha Barden Smith, during the early days of the Latter Day Saint movement. He was among the first generation of children raised in the church. The office of Presiding Patriarch was initially created to honor Joseph Smith, Sr., the father of the religion's founder. Before his death in 1840, Joseph Smith, Sr. declared his eldest living son, Hyrum, would receive the office of patriarch by virtue of lineal succession. Hyrum at this time was one of the most influential members of the church and was widely seen as the most likely successor to its leadership should he outlive his brother. However, in 1844, both Hyrum and Joseph Smith were assassinated by a mob in Carthage, Illinois.

This event left the church leaderless. By consensus, it was expected that the title of Presiding Patriarch would pass to Hyrum Smith's eldest son, John. However, because John Smith was only 11 years of age at the time of his father's death, the position was instead claimed by a younger brother of Joseph Smith, Jr., William, and later by the younger brother of Joseph, Sr., John Smith, who was known to the church as "Uncle John". Meanwhile, Hyrum's son John Smith traveled with the family of Heber C. Kimball to Winter Quarters, Nebraska. In 1848, John Smith, along with Kimball, reached the Salt Lake Valley to join Brigham Young, who had assumed leadership of the largest Latter Day Saint faction, the LDS Church.

In February 1855, the younger John Smith succeeded his great uncle, "Uncle John" Smith as Presiding Patriarch of the LDS Church, following the latter's death. In this capacity, he acted as voice in the setting apart of his younger half-brother, Joseph F. Smith as president of the church. He became the longest-serving Presiding Patriarch in LDS Church history, remaining in that position for 56 years, until his death from pneumonia in 1911 in Salt Lake City. Among his accomplishments during this time were a mission to Scandinavia, begun in 1862. Following his death, he was succeeded by his grandson, Hyrum G. Smith. Smith was buried in Salt Lake City.
