The True Church of Jesus Christ of Latter Day Saints was a denomination of the Latter Day Saint movement. Founded in the spring of 1844 in Nauvoo, Illinois by leaders dissenting from the Church of Jesus Christ of Latter Day Saints or Mormon church.

The reformed church's president was William Law, a former counselor to church president Joseph Smith, Jr.. He was joined by Wilson Law, Robert D. Foster, Charles A. Foster, Francis M. Higbee, Chauncey L. Higbee and Charles Ivins. Members of the reformed church believed that "Mormonism" as it had been originally practiced was true, but that the practice of plural marriage in particular was a corruption. This group was also responsible for printing the Nauvoo Expositor.
