The 2019 Montana Grizzlies football team represented the University of Montana in the 2019 NCAA Division I FCS football season. The Grizzlies were led by second-year head coach Bobby Hauck, ninth overall as he previously was head coach from 2003–2009, and played their home games on campus at Washington–Grizzly Stadium in Missoula, Montana as a charter member of the Big Sky Conference. They finished the season 10–4, 6–2 in Big Sky play to finish in a three-way tie for third place. They received an at-large bid to the FCS Playoffs where, after a first round bye, they defeated Southeastern Louisiana in the second round before losing to Weber State in the quarterfinals.
