James Colin Brewster (October 26, 1826 – January 8, 1909) was a co-founder of The Church of Christ (Brewsterite), a schismatic sect in the Latter Day Saint movement.
In November 1837, due to his persistent claims of being a prophet, Brewster was disfellowshipped from The Church of Jesus Christ of Latter-day Saints.
After the death of Joseph Smith in June 1844, Brewster began to accumulate followers in Springfield, Illinois, from Latter-day Saints who were searching for a new prophet-leader.
During the Reconstruction Era, he followed his brother, Orlando Hamlet Brewster, to Louisiana, where James taught at a school for African Americans in Ouachita Parish and attempted to farm with them.
Orlando had a role in the disputed presidential election of Rutherford B. Hayes and both Brewster brothers left Louisiana.
