(French pronunciation: [maʁi viktɔʁɛ̃]; April 3, 1885 – July 15, 1944), was a Canadian member of Brothers of the Christian Schools and a noted botanist in Quebec, Canada.

Subsequent administrations, both municipal and provincial, opposed the Garden as a boondoggle; however, Brother Victorin continued to champion its cause, promoting it at every opportunity, leading specimen-collection expeditions, recruiting Henry Teuscher as its designer, and protecting it from being converted into a military flight school, even during the Second World War.

At the Commission toponymy Quebec, a query on Marie-Victorin gives 69 results: mountains, lakes, roads, parks, buildings, etc., honor his memory.
