The 2023 Mountain West Conference Football Championship Game was a college football game which was played on December 2, 2023, at Allegiant Stadium in the Las Vegas-area community of Paradise, Nevada. It was the 11th edition of the Mountain West Conference Football Championship Game and determined the champion of the Mountain West Conference (MW) for the 2023 season. The game began at 12:00 p.m. PST and was aired on Fox. The game featured the Boise State Broncos and the UNLV Rebels.
Boise State, UNLV, and San José State all finished with a 6–2 conference record, creating a three-way tie. Since all three teams did not face each other during the season and no team was ranked in the College Football Playoff (CFP) rankings before the game, the three-way tie was broken by computer rankings from Anderson & Hester, Colley Matrix, Massey and Wolfe. UNLV finished with the best average rankings, while Boise State came in second and San José State at third. Therefore, the Broncos and Rebels secured their spots in the MW Championship. UNLV and Boise State did not play each other during the regular season. The Rebels had the higher average ranking and earned the right to host the title game.[1]
