John Campbell Greenway (July 6, 1872 – January 19, 1926) was an American mining, steel and railroad executive: a man of many trades in many states. He also had a distinguished career as a soldier, both cavalry and infantry.
In 1919 Greenway became a colonel of the infantry, and three years later he was promoted to brigadier general. Full of stamina, John Greenway continued to be active in business until his death in 1926 in New York City. In 1930 Arizona placed Greenway's statue in the U.S. Capitol's National Statuary Hall Collection. Greenway's great great grandfather Dr. Ephraim McDowell's statue was placed in the National Statuary Hall in 1929 by Kentucky.
A major thoroughfare in Phoenix, Arizona, Greenway Road, and Greenway High School in Phoenix is named in his honor.
