The 1997–98 Football League Cup (known as the Coca-Cola Cup for sponsorship reasons) was the 38th Football League Cup, a knockout competition for England's top 92 football clubs.
The competition began on 11 August 1997, and ended with the final on 29 March 1998, held at Wembley Stadium. The tournament was won by Chelsea, who beat Middlesbrough 2–0 in the final.
The 70 First, Second and Third Division clubs compete from the First Round. Each section is divided equally into a pot of seeded clubs and a pot of unseeded clubs. Clubs' rankings depend upon their finishing position in the 1996–97 season.
