The Little Brown Stein is a rivalry trophy awarded to the winner of the college football game between the University of Idaho Vandals and the University of Montana Grizzlies. The trophy is, as the name implies, a large stein mug with the results of all the games between the two painted on. The game was not played for fourteen seasons, from 2004 to 2017, and Montana retained the trophy. The series resumed 2018, when Idaho rejoined the Big Sky Conference for football.
