James Brown (c. 1734 – 9 November 1791) was a clergyman in the Scottish Episcopal Church, notable as one of a few Jacobite dissenters who refused to abandon their allegiance to the House of Stuart when directed to do so in 1788.
He married Helen Taylor, daughter of an Episcopalian minister, and they had a son, Robert, who would become a notable botanist, giving his name to his discovery of Brownian motion.
The Scottish Episcopal Church had long supported the House of Stuart, but found it impossible to support Charles' heir, his brother Henry Benedict Stuart, who was a cardinal of the Roman Catholic Church.
Accordingly, the bishops of the Scottish Episcopal Church met and agreed to recognise George III.
The following year Rose died, making Brown the last remaining minister to the Jacobite dissenters.
