Donald Mackenzie (June 15, 1783 – January 20, 1851) was a Scottish-Canadian explorer, fur trader and Governor of the Red River Colony from 1821 to 1834.
Born in Scotland, Mackenzie emigrated to Canada about 1800. He is related to several other distinguished MacKenzies in Canadian history. He and two or three of his brothers became involved in the fur trade and were engaged with the North West Company. In 1810, he left the employ of the North West Company to become a partner in the Pacific Fur Company (PFC), financed solely by John Jacob Astor.
Mackenzie traveled west from St. Louis, Missouri with an expedition of fellow PFC employees to the Pacific Northwest. The group experienced hard times in southern Idaho, and divided. Mackenzie’s fraction consisted of twelve total and struck north, eventually found the Salmon River and Clearwater River. They proceeded down the lower Snake River and Columbia River by canoe, and were the first of the Overland Astorians to reach Fort Astoria, on January 18, 1812.
