1991 Nevada Wolf Pack football team

The 1991 Nevada Wolf Pack football team was an American football team that represented the University of Nevada, Reno in the Big Sky Conference (BSC) during the 1991 NCAA Division I-AA football season. In their 16th season under head coach Chris Ault, the Wolf Pack compiled a 12–2 record (8–0 against conference opponents), won the BSC championship and lost to Youngstown State, the eventual national champion, in the NCAA Division I-AA Quarterfinals. They played their home games at Mackay Stadium.

This was the Wolf Pack's last year as a member of the BSC and I-AA (now FCS) as they joined the Big West Conference and the NCAA Division I-A—now the known as the NCAA Division I Football Bowl Subdivision (FBS)—for the 1992 season.
