It is the seventh consecutive national championship earned by the SEC and the third in four years for Coach Nick Saban's program.
Alabama (13-1) got its scoring started on the opening possession with a 20 yard rushing touchdown by Eddie Lacy to take the early lead. The drive went 82 yards, the first touchdown drive of the season given up by the Fighting Irish of over 75 yards this season.
After a three-and-out by Notre Dame, Alabama scored again, with A.J. McCarron hitting Michael Williams for a three-yard yard touchdown to make it 14-0.
The game may have gone a different direction if a fumble recovery by the Fighting Irish on the punt after their initial possession was not overturned due to a penalty. The officials said that a Notre Dame player interfered with the Alabama punt returner in catching the punt.
The first play of the second quarter saw a one-yard TD run by T.J. Yeldon to increase the lead to 21.
The Crimson Tide added to the insult with an 11-yard TD pass from McCarron to Lacy in the final minute of the first half.
Notre Dame (12-1) was outgained offensively 309-124 in the first half.
Alabama added another touchdown in the third quarter before Notre Dame finally got on the scoreboard. Everett Golson scrambled for a two-yard touchdown with just over four minutes left in the third.
The Fighting Irish scored again midway through the fourth when Golson scored from a yard out.
Both Lacy and Yeldon eclipsed 100 yards rushing for Alabama, with Lacy finishing with 140 yards on 20 carries and Yeldon adding 107 yards on 21 carries.
McCarron was almost flawless in the win, throwing for 264 yards and four touchdowns.
Golson finished 21-of-36 for 271 yards with a touchdown and an interception.
Notre Dame was held to just 42 yards rushing on 18 carries.
