Lyman Wight (May 9, 1796 – March 31, 1858) was an early leader in the Latter Day Saint movement. He was the leader of the Latter Day Saints in Daviess County, Missouri, in 1838. In 1841, he was ordained a member of the Quorum of the Twelve Apostles. After the death of Joseph Smith resulted in a succession crisis, Wight led his own break-off group of Latter Day Saints to Texas, where they created a settlement. While in Texas, Wight broke with the main body of the group led by Brigham Young. Wight was ordained president of his own church, but he later sided with the claims of William Smith, and eventually of Joseph Smith III. After his death, most of the "Wightites" (as members of this church were called) joined with the Reorganized Church of Jesus Christ of Latter Day Saints (RLDS Church).
