John Stuart (24 February 1740 – 15 August 1811) was a Church of England clergyman, missionary, educator, and Loyalist.

Upon receiving an appointment from the Society for the Propagation of the Gospel he was assigned as a missionary to the Mohawks at Fort Hunter, New York.

Stuart collaborated with Joseph Brant to translate the Gospel of St. Mark into the Mohawk dialect.

[2] Since Stuart was a Loyalist and an Anglican priest, he was harassed by American Revolutionary War rebels.

Stuart arrived in Canada with his wife, Jane (née Okill), three children and his black slaves.

Stuart realized that prospects of obtaining a more secure position or obtaining property in Montreal were low, so in 1783 he petitioned Governor Haldimand to allow him to move to Cataraqui (now Kingston), grant him land and appoint him Chaplain of the Garrison of Cataraqui.

Their eldest son, George Okill Stuart, would become rector of Kingston after the death of his father.
