Maurilio Fossati, O.SS.G.C.N., (24 May 1876 – 30 March 1965) was an Italian Cardinal of the Roman Catholic Church who served as Archbishop of Turin from 1930 until his death, and was elevated to the cardinalate in 1933.

Known as the "Green Flames", they were supported by sympathetic provincial clergy in the North, who pronounced the Germans to be "unjust invaders", whom it was lawful and meritorious to repel.

[4] Sister De Muro eventually saved over 500 Jewish people from being shipped to Nazi concentration camps, although Cardinal Fossati's actual role in the success of the efforts, if any, is unknown.
