The 2012 Allstate BCS National Championship Game was a postseason college football bowl game between the Alabama Crimson Tide and the LSU Tigers, and determined the national champion of the 2011 NCAA Division I FBS football season on Monday, January 9, 2012, at the Mercedes-Benz Superdome in New Orleans, Louisiana. The game was part of the 2011–2012 Bowl Championship Series and a rematch of regular season foes. Alabama beat LSU 21–0 to win their 14th national championship, marking the first shutout in a national championship game since the 1992 Orange Bowl and the first ever shutout in a BCS bowl game. The game had the third-lowest TV rating, 14.01, in the 14-year history of the BCS National Championship game.
It was LSU's first loss in a game played in New Orleans (which is near the LSU campus in Baton Rouge) since the 1987 Sugar Bowl. From 1987 through the 2011 regular season, LSU was 4-0 in bowl games in New Orleans (three Sugar Bowls and the 2008 BCS National Championship Game) and 5-0 in the city vs. Tulane.
LSU was selected to participate in the BCS National Championship Game after a 13–0 regular season that culminated with a 42–10 win over the University of Georgia in the 2011 SEC Championship Game. Alabama was picked as the other half of the match-up following an 11–1 campaign, with their only loss coming against LSU in overtime during the regular season. Over the following weeks, a series of upsets resulted in the Crimson Tide receiving a No. 2 ranking in the final BCS Rankings to qualify for the championship game. The selection of Alabama was controversial, and decried by writers such as Rick Reilly, and by fans who claimed other opponents, most prominently the Oklahoma State Cowboys (who finished second in most of the computer rankings), were more deserving of a spot in the game. The controversy lent support to the ever-increasing call for a college football playoff and supposed SEC bias, specifically with regard to Alabama. Ironically, it was the conferences whose teams finished 3rd and 4th (the Big 12 and the Pac-12) who had rejected the SEC's proposal for a 4-team playoff system in 2008. 
This game was the first time in the 14-year history of the BCS that the National Championship Game featured two teams from the same conference, let alone the same division (similar to what happened in the 2011 NCAA Division I Baseball Tournament six months prior, featuring two teams from the SEC East division, although that match-up came about through a playoff). This was also the first time that the BCS National Championship Game was a rematch from a regular season game, although the 1996 season's Bowl Alliance National Championship game was also a rematch, when Florida defeated Florida State 52–20 for the national title in the 1997 Sugar Bowl. As a result of the matchup, the SEC's streak of producing the BCS champion was assured of extending to six straight seasons.

Alabama won the coin toss with a call of "tails" and elected to defer their decision to the second half.
The game, largely a defensive struggle, was epitomized by LSU's first possession of the game. The Tigers fumbled the ball on the opening play and ultimately ended up punting the football to Alabama after failing to gain a first down. The rest of the first half was dominated by both defenses. Alabama got within field goal range four times and kicker Jeremy Shelley made three of his attempts to give Alabama a 9–0 lead at halftime. LSU gained only one first down and was unable to cross the 50-yard line for the entire first half.
The second half played out much the same as the first. Alabama's defense allowed LSU to cross the 50-yard line only once and gave up only four more first downs. Alabama was able to add 6 more points from a couple of Shelley field goals and another 6 points on the game's only touchdown on a 34-yard rush by Heisman Trophy finalist Trent Richardson.
