John Campbell Greenway (July 6, 1872 – January 19, 1926) was an American mining, steel and railroad executive. He also had a distinguished career as a soldier, both cavalry and infantry.
Greenway was born in Huntsville, Alabama, and attended Phillips Academy, Andover and then the University of Virginia and graduated in 1895 from the Sheffield Scientific School of Yale University. His early employment as a furnace helper for the Carnegie Steel Company was brief, as he joined Roosevelt's Rough Riders in the Spanish–American War. After earning a Silver Star for his courageous service at the Battle of San Juan Hill, he was recommended for promotion to brevet captain by Colonel Roosevelt.
Beginning in 1899, Greenway held executive positions in a number of mine, steel, and railroad companies. He supervised development of United States Steel's open pit Canisteo Mine and Trout Lake Washing Plant in Coleraine, Minnesota, one of the first large-scale iron ore benefication plants in the world. Following the successful commissioning of the Trout Lake plant, in 1911 Greenway was recruited by the Calumet and Arizona Mining Company (led by US Steel executives) to develop their newly acquired New Cornelia Mine in Ajo, Arizona. He developed the Ajo townsite and developed the New Cornelia into the first large open pit copper mine in Arizona. Greenway served for one year as a regent of the University of Arizona before the United States entered World War I.
