Mackenzie, Roderick (1760?-1844), was a Canadian frontiersman and fur trader. He accompanied his cousin, Sir Alexander Mackenzie, on a trip to western Canada in 1786. He commanded Fort Chipewyan in northeastern Alberta from 1789 to 1793. Mackenzie was a capable administrator rather than a trailblazer. He returned to eastern Canada in 1797, and became a partner in the North West Company in 1799. Later, he served in the Legislative Council of Lower Canada. Mackenzie was born in Scotland. He died on Aug. 15, 1844.
