1997 LSU Tigers football team

The 1997 LSU Tigers football team represented Louisiana State University in the college football season of 1997–1998. Coached by Gerry DiNardo in his third season at LSU, the Tigers played their home games at Tiger Stadium in Baton Rouge, Louisiana.

The Tigers began the season with high expectations following their first 10-win season since 1987. LSU's season was highlighted by a stunning 28–21 home upset of the top ranked Florida Gators (ending Florida's 25-game winning streak in SEC play) and an victory over the Notre Dame Fighting Irish, who had defeated the Tigers in Baton Rouge during the regular season. The Tigers tied for the SEC West title for the 2nd straight year, but Auburn had won a dramatic game in Baton Rouge earlier in the season and therefore represented the West in the SEC Championship.
