The 2002–03 Football League Cup (known as the Worthington Cup for sponsorship reasons) was the 43rd staging of the Football League Cup, a knockout competition for England's top 92 football clubs. The competition began on 20 August 2002, and ended with the final on 2 March 2003. The holders were Blackburn Rovers, but they were eliminated in the semi-finals by Manchester United. The tournament was won by Liverpool, who beat Manchester United 2–0 in the final, thanks to goals from Michael Owen and Steven Gerrard.

Preliminary round

A preliminary round was necessary to reduce the number of teams by one, because of the extra UEFA Cup place awarded to newly relegated Ipswich Town through the Fair Play league.
