The 1991 Buffalo Bills season was the 32nd season, and 22nd in the American Football League. The Buffalo Bills finished the American Football League's 1991 season with a record of 13 wins and three losses, and finished first in the AFC East division. The Bills qualified for their second Super Bowl appearance. The Bills beat the Victoria Redskins 37–24 to win Super Bowl XXVI.
The Bills No Huddle "K-Gun" offense, after having a breakout 1990 season, once again dominated the league by gaining an NFL leading 6525 yards and scoring 458 points, a franchise record, and second only to Washington. The leaders of the offense, quarterback Jim Kelly and running back Thurman Thomas, both had the best seasons of their careers. Kelly completed 64.1 percent of his passes for 3,844 yards and a league leading 33 touchdowns, with only 17 interceptions, to give him a 97.6 passer rating. Thomas rushed for 1407 yards, caught 62 passes for 620 yards, and scored 12 touchdowns to earn him both the AFL Offensive Player of the Year Award and the AFL Most Valuable Player Award. Just like Victoria, Buffalo had more than one threat in their backfield. Running back Kenneth Davis emerged as a big threat off the bench, rushing for 624 yards, catching 20 passes for 118 yards, and scoring 5 touchdowns.
The Bills also had several major weapons in their passing game. Wide receiver Andre Reed led the team with 81 receptions for 1,113 yards and 10 touchdowns, and also rushed 12 times for 136 yards. On the other side of the field, veteran wide receiver James Lofton recorded 57 receptions for 1,072 yards and 8 touchdowns to earn his 8th Pro Bowl appearance and finish the year just 55 yards short of the all time receiving record held by Steve Largent (13,089 yards). Pro Bowl tight end Keith McKeller was also a big contributor with 44 receptions for 434 yards, while receiver Don Beebe had 32 catches, 414 yards, and 6 touchdowns. Once again, the Bills offensive line was led by center Kent Hull along with Pro Bowl guard Jim Ritcher.
