The 2015 Sports Authority Mountain West Football Championship Game determined the 2015 football champion of the Mountain West Conference (MW).

After the 2013 phase of Mountain West Conference realignment, the league added two new members, San Jose State and Utah State[1] for the 2013 season.

By adding two new members for a total of 12 football members (11 all-sports members and football-only Hawaii), the MW was able to split into two divisions, the Mountain and the West, and to organize an annual conference championship game.
