John Walter Grant MacEwan, OC AOE (August 12, 1902 – June 15, 2000) was a Canadian farmer, Professor at the University of Saskatchewan, Dean of Agriculture at the University of Manitoba, the 28th Mayor of Calgary and both a Member of the Legislative Assembly (MLA) and the ninth Lieutenant Governor of Alberta, Canada. MacEwan University in Edmonton, Alberta and the MacEwan Student Centre at the University of Calgary as well as the neighbourhoods of MacEwan Glen in Calgary and MacEwan in Edmonton are named after him.

MacEwan's grandparents were Highland Scottish. George MacEwen (Grant MacEwan changed his name to "MacEwan"with an "a" sometime in the 1920s), his paternal grandfather, came from Stirling, Scotland to farm in Guelph, Ontario, and married Annie Cowan, another Scot. These two had a son, Alexander MacEwen. After leaving home, Alexander went to Brandon, Manitoba to begin a farm of his own, and was introduced to Bertha Grant (his neighbour James Grant's sister) and soon got married. Bertha and Alexander were MacEwan's parents. Bertha was a devout Presbyterian. This strong Scottish, Presbyterian, and agriculture-driven heritage was influential in MacEwan's life.
