Charles James Stewart (13 or 16 April 1775 – 13 July 1837) was an English Church of England, clergyman, bishop, and politician. He was the second Bishop of Quebec from 1826 to 1837, and in connection with this was appointed to the Legislative Council of Lower Canada.
Born in London, England, the third surviving son of John Stewart, 7th Earl of Galloway, and his second wife, Anne Dashwood, Stewart received a Bachelor of Arts degree from Corpus Christi College, Oxford in 1795 and a M.A. in 1799 from All Souls College, Oxford. He was ordained to the diaconate in December 1798 and to the priesthood in May 1799. From 1799 to 1826, he was collated to the rectory of Orton Longueville in Cambridgeshire. In 1807, he arrived in Lower Canada as a missionary settling in Montreal. He soon moved to Saint-Armand and helped to build Trinity Church, Frelighsburg, the first regular place of Anglican worship in the Eastern Townships. In 1826, he was appointed Bishop of Quebec. He died in London in 1837.
