John Alexander MacAulay CC (1895 – June 11, 1978) was a Canadian lawyer, businessman, and a volunteer worker in the Canadian Red Cross Society. Born in Morden, Manitoba, he obtained his LL.B. from the University of Manitoba in 1918 while serving in the Canadian Medical Corps. He was a partner at the Manitoba law firm of Aikins, MacAulay & Thorvaldson and specialized in tax law. From 1959 to 1965, he was chairman of the Board of Governors of the League of Red Cross Societies and was chairman when the Red Cross received the 1963 Nobel Peace Prize. He was the first Canadian to be awarded the Henry Dunant Medal, the highest honor the Red Cross can award. An avid art collector, his collection is now housed in the Winnipeg Art Gallery. In 1967, he was made a Companion of the Order of Canada.
