Allan MacNab, Canadian soldier, lawyer, and politician, Premier of Canada West (died 1862)

Sir Allan Napier MacNab, 1st Baronet was a Canadian political leader, land speculator and property investor, lawyer, soldier, and militia commander who served in the Legislative Assembly of Upper Canada twice, the Legislative Assembly for the Province of Canada once, and served as joint Premier of the Province of Canada from 1854 to 1856. MacNab was "likely the largest land speculator in Upper Canada during his time" as mentioned both in his official biography in retrospect and in 1842 by Sir Charles Bagot.

Joint premiers of the Province of Canada were the prime ministers of the Province of Canada, from the 1841 unification of Upper Canada and Lower Canada until Confederation in 1867.
