Isaac Morley Whiting (October 1, 1842 – May 28, 1922) was a Latter Day Saint leader who served as the third president of The Church of Jesus Christ (Cutlerite), from 1902 to 1922.

During Whiting's tenure, the Cutlerites successfully established an Order of Enoch, as advocated by founding prophet Joseph Smith during the early years of his movement.

When he was still very young, his family relocated first to Winter Quarters, Nebraska, and later to Manti, Iowa, where his parents joined Mormon leader Alpheus Cutler in forming the Church of Jesus Christ, commonly known as "Cutlerites."

[2] Trained as a wagon-maker, Whiting moved with his family to Clitherall, Minnesota, where he served as First Counselor to his father while he was leader of the Cutlerite community.

By 1912 these endeavors had borne fruit, and a church corporation had taken charge of Cutlerite properties in Clitherall.
