1991 NCAA Division I-A football season

The 1991 NCAA Division I-A football season was the main college football season sanctioned by the National Collegiate Athletic Association (NCAA). The season began on August 28, 1991, and ended on January 1, 1992. For the second consecutive season, there was a split national championship. Both the Miami Hurricanes and the Washington Huskies finished the season undefeated (12–0) and with the top ranking in a nationally recognized poll.

Under the conference-bowl selection alignments of the time, the Hurricanes and Huskies could not meet in a decisive title game because Washington was slotted into the Rose Bowl as the Pac-10 champions, and the other spot in the Rose Bowl was automatically given to the Big Ten champions (in 1991, that was Michigan). The Rose Bowl's selection terms later thwarted potential title matchups of undefeated teams following the 1994 and 1997 seasons. Following the 1998 Bowl Championship Series (BCS) realignment, several Pac-10 and Big Ten teams were able to play in a BCS title game instead of being forced to play a non-title contender in the Rose Bowl; these include the Ohio State Buckeyes in 2002, 2006 and 2007, the USC Trojans in 2004 and 2005 and the Oregon Ducks in 2010.

Miami closed the 1991 season with a 22–0 shutout over No. 11 Nebraska in the Orange Bowl, but their season was defined by a dramatic November victory over then No. 1 ranked and perennial rival Florida State. That game ended with the FSU place kicker missing a field goal, wide right, which would become a theme in the Florida State–Miami football rivalry; this game later took on the moniker "Wide Right I." Nebraska lost to both national champions in 1991 and finished at 9–2–1, ranked No. 15 in the AP poll.

Washington posted a 15-point victory at No. 9 Nebraska in September, a seven-point win at No. 7 California in October, and repeated as Pac-10 champions. They went on to win the Rose Bowl by 20 points over No. 4 Michigan, the Big Ten champions who featured Heisman Trophy winner Desmond Howard; it was Washington's second consecutive Rose Bowl win. Michigan finished at 10–2, ranked at No. 6 in both polls.

The Florida Gators captured their first official SEC title in school history (they had previously won the 1984 SEC title, but it was later vacated) in dominating fashion. Alabama finished second in the SEC with an 11–1 record, but were shutout 35–0 by the Gators. Florida's luck ran out in the Sugar Bowl, as No. 18 Notre Dame powered their way to a 39–28 win.
