Leonard Rich (1800–1868) was an early leader in the Latter Day Saint movement and one of the inaugural seven Presidents of the Seventy.

In 1834, the Kirtland High Council rebuked him for "transgressing the word of wisdom and for selling the revelations [scriptures] at an extortionary price.

[4] On April 6 of that year, he and other presidents of the Seventy who were ordained high priests prior to their call were released.

In 1845, Reuben McBride reported that Rich was a leader of rioters who broke into and took possession of the Kirtland Temple.

[7] In January 1847 Rich, along with William E. McLellin and Jacob Bump, organized the Church of Christ at Kirtland.
