The 1991 College Football All-America team is composed of college football players who were selected as All-Americans by various organizations and publications that chose College Football All-America Teams in 1991. It is an honor given annually to the best American college football players at their respective positions.

The National Collegiate Athletic Association (NCAA) recognizes five selectors as "official" for the 1991 season.^[1] They are: (1) the American Football Coaches Association (AFCA);^[2] (2) the Associated Press (AP);^[3] (3) the Football Writers Association of America (FWAA);^[2] (4) the United Press International (UPI);^[4] and (5) the Walter Camp Football Foundation (WCFF).^[5] Other notable selectors included Football News,^[2] Scripps Howard (SH),^[6] The Sporting News (TSN), and the Newspaper Enterprise Association in conjunction with World Almanac.

Nine players were unanimously selected by all five official selectors. They are: running back Vaughn Dunbar of Indiana; wide receiver Desmond Howard of Michigan; center Jay Leeuwenburg of Colorado; tackle Greg Skrepenak of Michigan; defensive ends Santana Dotson of Baylor and Steve Emtman of Washington; linebacker Robert Jones of East Carolina; defensive back Terrell Buckley of Florida State; and punter Mark Bounds of Texas Tech.^[1] Desmond Howard also won the 1991 Heisman Trophy.
