Simon McTavish (c.1750 – 6 July 1804), of Montreal was a Scottish-born fur trader and the chief founding partner of the North West Company. He was a member of the Beaver Club and was known as the Marquis for his pre-eminent position in the fur trade and his refined style of living. Both McTavish Street and the McTavish Reservoir in Montreal are named for him. His home and monument in the Golden Square Mile were longstanding landmarks in Montreal.
