Roger Brereley (Brearley, Brierley etc.) (1586–1637) was an English clergyman, known as the founder of the Grindletonian sect. His actual views are known from surviving sermons, perhaps reconstituted from notes; those held by the Grindletonians may well have differed considerably from those attributed to them by opponents in polemics. Brereley was in his own view a supporter of Calvinistic orthodoxy, not a sectary, and he censures Jacobus Arminius.
