The 1984 Montana State Bobcats football team represented the Montana State University (MSU) in the 1984 NCAA Division I-AA football season. The team was led by Dave Arnold in his second season as a head coach. The Bobcats played their home games at Reno H. Sales Stadium.
After going 1âÂÂ10 the previous season and finishing last in the Big Sky, the Bobcats had one of the biggest turnarounds in all of college football in 1984, finishing the regular season with an overall record of 9âÂÂ2, including a 35âÂÂ31 win over Division I-A Fresno State, and won the Big Sky title. The Bobcats received a bid to the Division I-AA playoffs, defeating Arkansas State and Rhode Island en route to the I-AA Championship Game. In the championship game, Montana State defeated Louisiana Tech 19âÂÂ6 for the program's first I-AA national title, and first national title since the 1976 team won the NCAA Division II national championship. This would be the Bobcats' last national championship win until 2025.
