Thomas Fraser (1749 – October 18, 1821) was a soldier and political figure in Upper Canada. He was born in Stratherrick, Inverness, Scotland in 1749. His family came to North America in 1767 and settled on the estate of Sir William Johnson in Tryon County, New York. In 1777, he and his brother were captured while trying to escape to Quebec. They escaped and joined Major-General John Burgoyne at Fort Edward. After the fall of Saratoga, they escaped north to Quebec. In 1779, they served as border guards at the Yamaska River and later became Lieutenants in Edward Jessup's Loyal Rangers.
