Benjamin Brook (1776–1848) was an English nonconformist minister and religious historian.
Resigning his ministerial duties in 1830, from failing health, he lived at Birmingham, still continuing his studies, and publishing.
Alexander Gordon in the Dictionary of National Biography comments that Brook was a better biographer than historian.
At the time of his death he was collecting materials for a history of puritans who emigrated to New England.
He is said to have been one of the last who retained among the congregationalists the old ministerial costume of shorts and black silk stockings.
