Marcus Martin (1893–1981) was an Australian architect. He was an associate of the Royal Institute of British Architects, fellow of Royal Institute of Architects, and honorary secretary to the Royal Victorian Institute of Architects. Martin was probably the most popular architect amongst the wealthy Toorak establishment in Melbourne, Australia during the interwar period and produced many buildings that exhibited his hallmark of restrained modernism. Martin was a Lieutenant in World War I where he suffered a gun shot wound in France; Martin also enlisted in World War II.
