Charles C. Riley (May 13, 1902 – July 19, 1971) was an American football player and coach. He was born in Indianapolis, Indiana. Riley was the starting quarterback and punt returner for most of the 1927 season at the University of Notre Dame. He is mostly remembered for his last game with the team—a controversial 7–6 victory against USC at Soldier Field in Chicago before the largest crowd ever to witness a football game at that time, estimated to be 120,000 in attendance.
