The Montana State Bobcats football program competes in the Big Sky Conference of the NCAA's Division I Football Championship Subdivision for Montana State University. The program began in 1897 and has won three national championships. It is the only college football program in the nation to win national championships on three different levels of competition, NAIA, NCAA Division II, and NCAA Division I-AA. Through the 2018 season, the Bobcats had played in 1,005 games with an all-time record of 500–485–32.
The first championship came in Montana State's last season in the Rocky Mountain Athletic Conference, which moved to NAIA in 1952. The national championship was the first ever for the RMAC and was also the first time the NAIA had a football champion. The Bobcats were members of the RMAC from 1917 to 1956, after being an independent from 1897 to 1916. MSC rejoined the NCAA in 1957, and had one of its most successful runs as an independent from 1957 to 1962 with six straight winning seasons, including an 8–2 mark in 1957 and 8–1 in 1958. In 1963, Montana State became a charter member of the Big Sky Conference and has since won two national championships.
