The Mountain West Conference Football Championship Game is an annual postseason college football game played to determine the champion of the Mountain West Conference (MW).

From 1999 to 2012, the champion of the Mountain West was determined by regular season record. Beginning in 2013, following the expansion to twelve members and the division of the conference into Mountain and West Divisions, the conference championship game was held between the two division winners. The Mountain West is one of four conferences to have its championship game at a campus site, along with the American Athletic Conference, Conference USA, and the Sun Belt Conference.

The most recent 2022 championship game was the last to feature division winners. On May 20, 2022, the MW announced that it would eliminate its football divisions effective with the 2023 season, instead sending the top two teams in the conference standings to the title game. Two days earlier, the NCAA Division I Council had approved a rule change that gave all FBS conferences full freedom to determine the participants in their football championship games.

The inaugural MW Championship Game was played on December 7, 2013, at Fresno State's Bulldog Stadium and televised by CBS.

Membership is current for the upcoming 2026 season, reflecting membership changes that become official that July.
