Walter Frederic "Wally" Koppisch (June 6, 1901 – November 2, 1952) was an American football halfback in the National Football League for the Buffalo Bisons and New York Giants. He attended Columbia University. At 23 years old, Koppisch, a local celebrity and high school football star, was named the head coach of the Buffalo Bisons, making him among the youngest head coaches in NFL history. Koppisch is considered one of the earliest busts in the NFL, having spectacularly failed to meet the high expectations of him in his lone season in Buffalo, although the expectations may have been unwarranted due to changes outside of his control.
