Charles Blancher Thompson (January 27, 1814 – February 27, 1895) was an American leader of a schismatic sect in the Latter Day Saint movement from 1848 to 1858.

Among the several aspirants to be Smith's successor, Thompson initially accepted James J. Strang as the rightful leader of the Latter Day Saints.

Thompson began to claim that he was the reincarnation of the biblical Ephraim and that he was to be known as "Baneemy, patriarch of Zion".

In September 1853, Thompson moved his followers to Monona County, Iowa, north of Council Bluffs, where they established a communitarian commune called Preparation.

Thompson enforced strict rules of behavior among his followers and published a variety of periodicals while in St. Louis and in Iowa, including Zion’s Harbinger and Baneemy’s Organ, Preparation News and Ephraim's Messenger.
