The 1978 College Football All-America team is composed of college football players who were selected as All-Americans by various organizations and writers that chose College Football All-America Teams in 1978. The National Collegiate Athletic Association (NCAA) recognizes four selectors as "official" for the 1978 season. They are: (1) the American Football Coaches Association (AFCA) based on the input of more than 2,000 voting members; (2) the Associated Press (AP) selected based on the votes of sports writers at AP newspapers; (3) the Football Writers Association of America (FWAA) selected by the nation's football writers; and (4) the United Press International (UPI) selected based on the votes of sports writers at UPI newspapers. Other selectors included Football News (FN), the Newspaper Enterprise Association (NEA), The Sporting News (TSN), and the Walter Camp Football Foundation (WC).
