Rupert J. Fletcher (May 15, 1896 – November 22, 1974) was a Latter Day Saint leader who served as the sixth president of The Church of Jesus Christ (Cutlerite) from 1958 to 1974.

He also authored, in company with his wife Daisy, a compendium of Cutlerite history and doctrine, entitled Alpheus Cutler and The Church of Jesus Christ.

In his early years, he worked on his father's farm and also as a cowboy in Montana before joining the Cutlerite community in Independence, Missouri.

Rejecting this illegal act, the Missouri majority continued to sustain Whiting, and following his death, they elected Rupert Fletcher to succeed him.

The book combined several pamphlets and articles Fletcher had written on various theological themes related to Cutlerite teachings.
