James Glenie (or Glennie) FRSE FRS (1750 – 23 November 1817) was a Scottish soldier, businessman and political figure associated with New Brunswick.
Later, working for Governor Frederick Haldimand, Glenie was charged with establishing a barracks on an island at the east end of Lake Ontario.
After a series of disputes with the commanding officer on the island, he was put to work at Sorel instead while awaiting a court martial.
He encountered opposition in this enterprise from Thomas Carleton, governor for the province, who had taken part in Glenie's earlier court martial.
In January 1794, he was elected a Fellow of the Royal Society of Edinburgh, upon the proposal of John Playfair, Thomas Charles Hope and Andrew Duncan.
[3] A witness for the crown in the 1809 trial of Gwyllym Lloyd Wardle, he was severely criticised by Lord Ellenborough, the judge, and lost his reputation and positions.
