Fort Douglas was the Selkirk Settlement (Red River Colony) fort and the first fort associated with the Hudson's Bay Company near the confluence of the Red and Assiniboine rivers in today's city of Winnipeg. Named for Thomas Douglas, 5th Earl of Selkirk, founder of the Selkirk Settlement, the fort was built by Scottish and Irish settlers beginning in 1813. Completed in 1815, it was in the immediate vicinity (down river) of the North West Company establishment, Fort Gibraltar.
