The 1915 college football season had no clear-cut champion, with the Official NCAA Division I Football Records Book listing Cornell, Minnesota, Oklahoma, and Pittsburgh as having been selected national champions in later years. Only Cornell (named by four major selectors) and Pittsburgh (named by one) claim national championships for the 1915 season.
