The 1998 LSU Tigers football team was an American football team that represented Louisiana State University (LSU) as a member of the Western Division of the Southeastern Conference during the 1998 NCAA Division I-A football season. In their fourth year under head coach Gerry DiNardo, the team compiled a 4–7 record, with a conference record of 2–6, and finished fifth in the Western Division.[1]
In the beginning of the season, expectations were high as LSU had tied for the SEC West title but lost tiebreakers the previous two seasons. After a 3–0 start and No. 6 national ranking, the Tigers' season stunningly fell apart. They finished 1–7 in the last eight games of the season with many close losses, and finished 4–7, their seventh losing season out of the last ten. The loss at Ole Miss was LSU's first overtime game.
