Benjamin Carier (1566–1614) was an English clergyman, a fellow of Chelsea College who was a well-publicised convert to Catholicism.
He was presented to the vicarage of Thurnham in the same county, with the church of Aldington annexed, on 27 March 1600, and that benefice till 1613.
In 1602 he was presented, by Archbishop John Whitgift, whose domestic chaplain he then was, to the sinecure rectory of West Tarring in Sussex.
In 1608 he was nominated one of the first fellows of Chelsea College, projected by Matthew Sutcliffe as a seminary for defenders of Protestantism.
Carier’s printed Missive addressed to the king from Liège, 13 December 1613, made his conversion public.
