The 1908 Auburn Tigers football team represented Auburn University in the 1908 college football season. The team went 6–1, outscoring opponents 158–10. Auburn featured a strong defense that held all opponents scoreless except the 10–2 loss to LSU. This team was the first during the second term of coach Mike Donahue at Auburn.
In a game of a 20- and 15-minute halves, Auburn scored three touchdowns in the first half to put away Howard College at West End Park in Birmingham. Despite being outweighed by Howard, Auburn had success running against the Bulldogs' tackles in the first half. The second half saw no score on either side with Auburn held in check by the punting of Bennie, Howard's left tackle. Both teams were reported to show a lack of preparation, with Auburn's talent making the difference in the game.
In a game where the Tigers were not forced to punt, Auburn easily defeated the high school team from Gordon College in quick game at the Auburn athletic field. Auburn took the opening kickoff and drove for its first touchdown in the first two minutes, followed by four more touchdowns before the end of the half through the rushing of L. W. Hardage and D. Herron. Auburn's scrubs scored two more touchdowns in the second half to finish out the game.
Auburn was held to a single score in the first half, but wore down Mercer's line in the second half, scoring three touchdowns behind the running of L. W. Hardage. Mercer's Poole returned an Auburn interception 70 yards before being dragged down short of the goal line by Auburn halfback W. W. Wynne, which was the only threat to score the Baptists had all game.
Sewanee held the ball for most of the first half, exploiting Auburn's tackles—brought in against the inside run—with runs around end. Sewanee was unable to score, however, with Auburn's G. B. Sparkman recovering a Sewanee fumble on the Auburn two yard line. Auburn began to move the ball consistently on the visitors late in the first half, ending the period in Sewanee territory. In the second half, changes in Auburn's defense stymied Sewanee's end runs and field position gradually shifted in Auburn's favor. With seven minutes left in the game, Auburn's L.W. Hardage returned a Sewanee punt 45 yards for the game's only touchdown. 
Undefeated LSU met undefeated Auburn for the top spot in the SIAA at the Auburn athletic field. Auburn fumbled to LSU on its opening drive, and after an unsuccessful series of downs by each team, LSU launched a 51-yard scoring drive capped by a 40 yard touchdown pass from Fenton to Lally to bring the score to 5–0 in LSU's favor. Later in the half, Auburn's T.C. Locke blocked an LSU punt which was recovered by LSU's Fenton behind his own goal for a safety. After a short LSU drive in the second half, the teams traded free kicks on goal, none of which were successful, before Fenton returned an Auburn kick 35 yards to the Auburn 40 yard line. LSU drove to the Auburn 25, where Lally scored a touchdown around left end. LSU missed their second PAT of the game to leave the score at 10–2 in the visitor's favor. The remainder of the game was made up of short drives, kicks, and several penalties, including an ejection of LSU's captain Gandy for unnecessary roughness.
