Susan Brittain Ganong B.Sc., LLD (March 18, 1873 – April 29, 1961) was a widely respected Canadian educator and proprietor of the Netherwood School for girls in the Province of New Brunswick.
She was born in Carleton, New Brunswick (now West Saint John), and was known in the family as "Suzie" in order to distinguish her from her mother with the same first name.
Her family moved to the town of St. Stephen where her father and uncle Gilbert founded the Ganong Bros. chocolate company.
She also put in place a program for the teaching of the French language, a pioneering effort in a very English institution designed to develop an understanding between Canada's two founding cultures.
Susan Ganong died on April 29, 1961, in Rothesay and was buried with family members in the St. Stephen Rural Cemetery.
