Donald Manson (1796–1880) was a Scottish-Canadian fur trader of the Hudson's Bay Company and a pioneer of British Columbia.

He was the founder, along with Chief Factor James McMillan and metis François Annance, of Fort Langley, British Columbia.

[1][2][3] Donald Manson started his career in the Hudson's Bay Company, seated in Montreal, Canada, around 1817.

In 1827, Manson helped build Fort Langley with McMillan and metis François Annance, where James Murray Yale, the future father-in-law of his son, would be the commander.

[6][2][3] From 1829 to 1830, he was sent to Fort Astoria, the main trading post of John Jacob Astor before being taken by the Hudson's Bay Company.

In 1833, with Mr. Anderson, Manson conceived a circulating library among the officers of the Hudson's Bay Company, being the first of its kind on the Pacific Slope.

[3] He bought land and a farm from Dr. Robert Newell at Champoeg, Oregon, where he would live with his family until his death.

[3] His son William Manson married the daughter of chief trader Donald McLean, and graduated from Edinburgh University in Scotland.
