John Fraser (1721 – 16 April 1773) was a Scottish-American explorer and fur trader who served as a lieutenant during the French and Indian War, after the French captured his home during the conquest of the nearby Fort Prince George. Fraser served under George Washington during the failed attempt to reclaim the fort.

He subsequently served as Chief Scout of the Braddock Expedition. Fraser spoke with George Washington at Fort St-Mathieu when Haytham Kenway infiltrated it to learn of Braddock's location; he expressed disappointment at the news Braddock had turned down a truce with the French. After the expedition's failure, Fraser gave up reclaiming his home and moved to Tuscarora Valley.
