John Martin Mugar[1] (April 5, 1914 – March 23, 2007) was an American business executive of Armenian descent.

His great-grandfather on his mother's side managed an orphanage in Armenia for missionaries of the American Congregational Church.

Both were eventually shipped out to the Pacific Theater: Helen to New Guinea and John to Okinawa, where he was commissary officer of an amphibious unit, Acorn 44.

Under his leadership, Star Market was the first to implement many innovations in the supermarket industry, such as unit pricing, meats wrapped in cellophane,[4] in-store banks and florists, as well as installing conveyor belts that carried bags of groceries to a central pickup station at the store parking lot.

[5] Mugar instituted programs of work/study for his employees in association with local universities and was particularly interested in encouraging women to assume a greater role in management, which was evidenced by his instrumental role in the founding of the school of management at Simmons College in Boston.

[7] Mugar and his wife couple lived in Belmont, Massachusetts, for many years before retiring to Marco Island, Florida.
