Benjamin Brewster (November 25, 1860 – 2 February 1941) was the Episcopal Bishop of Maine and Missionary Bishop of Western Colorado.
He was born in New Haven, Connecticut, the son of the Rev. Joseph Brewster and Sarah Jane Bunce. He was a direct descendant of both Love Brewster, a passenger with his father, mother and brother, Wrestling, aboard the Mayflower and a founder of the town of Bridgewater, Massachusetts; and of Elder William Brewster, the Pilgrim colonist leader and spiritual elder of the Plymouth Colony, and passenger aboard the Mayflower and one of the signers of the Mayflower Compact.
His brother was the Right Rev. Dr. Chauncey Bunce Brewster, the fifth American Episcopal bishop of the Episcopal Diocese of Connecticut.
After preparation in the Hopkins Grammar School, he graduated with a B.A. in 1882 from Yale University, where he was a member of Skull and Bones, and then he received his B.D. in 1886 from the General Theological Seminary, New York City. Meanwhile, he taught school in Cleveland, Ohio, during 1882-1883.
