The 2021 Montana State Bobcats football team represented Montana State University in the Big Sky Conference during the 2021 NCAA Division I FCS football season. Led by first-year head coach Brent Vigen, the Bobcats played home games on campus at Bobcat Stadium in Bozeman, Montana.
Montana State finished the regular season at 9–2 (7–1 in Big Sky, second), losing only to Wyoming (FBS, Mountain West) and rival Montana.[1] Seeded eighth in the FCS postseason, they received a first-round bye, then defeated UT Martin, #1 Sam Houston, and South Dakota State. MSU advanced to the championship game in Texas on January 8, 2022, but fell 38–10 to #3 North Dakota State.[2]
On July 26, 2021, during the virtual Big Sky Kickoff, the Bobcats were predicted to finish fourth in the Big Sky by both the coaches and media.[3]
