Susannah Oland (1818–1885) was an Englishwoman who immigrated to Canada.
She was the creator of a beer recipe which became the basis for founding Canada's oldest independent brewery, Moosehead Brewery.
Though she was credited with running the operation as well as acting as chief brewer, the business was incorporated in the name of her husband and sons.
When her husband died, the partners sold their interests to a manager, whom Oland was able to buy out eight years later.
She continued running the business until her death.
