Martha Kostuch (July 8, 1949, Moose Lake, Minnesota, United States — April 23, 2008, Rocky Mountain House, Alberta, Canada) was a Canadian veterinarian and an award-winning environmentalist. In her veterinary work, she identified reproductive and immunological problems among cattle to air pollutants, like sulphur dioxide, from the sour gas industry in the region. Her successful campaign to reduce that air pollution marked the beginning of her work as an environmentalist.
