James Marshall (1796–1855) was a Scottish minister, of the Church of Scotland, and from 1841 of the Church of England.
Born at Rothesay, Bute, on 23 February 1796, he was the son of Hugh Marshall, a doctor who died in 1806, and his wife Elizabeth Wilson. The family moved to Paisley, and he was educated at Paisley grammar school, the University of Glasgow and the University of Edinburgh.
On 2 September 1818 Marshall was licensed to preach by the presbytery of Glasgow; his calm preaching style was noticed by Thomas Chalmers. First assisting his mother's friend, Dr. Robert Balfour, at the Outer High Church, Glasgow, he succeeded to Balfour's charge at his death in 1819. In 1828 he was appointed by the Edinburgh town council to the Tolbooth Kirk.
Before the Disruption of 1843 in the Church of Scotland, Marshall generally sympathised with non-intrusionist party; but in the event he broke with the Free Church and became an Anglican. He sent in his resignation to the presbytery of Edinburgh on 29 September 1841, and, after being confirmed by Charles Terrot, the Bishop of Edinburgh, was ordained by Edward Maltby, the Bishop of Durham as curate to William Stephen Gilly at Norham (19 December). He took priest's orders on 6 February 1842, and was appointed to the rectory of St. Mary-le-Port, Bristol.
