General Thomas Carleton (c. 1735 – 2 February 1817) was an Irish-born British Army officer who was promoted to colonel during the American Revolutionary War after relieving the siege of Quebec in 1776.
Born in Strabane, County Tyrone, in Ulster, Ireland, to Christoper Carleton and his wife Catherine Ball, he was the younger brother of The 1st Baron Dorchester.
He refused when in 1782 Haldimand demanded that he resign his position as quartermaster general before his planned departure for New York, where his brother Guy had replaced the disgraced Henry Clinton.
He was made major-general in the regular army on 12 October 1793, and colonel commandant of a battalion of the 60th (Royal American) Regiment of Foot in August 1794.
