The 1979–80 Football League Cup was the 20th season of the Football League Cup, a knockout competition for England's top 92 football clubs. The winners qualified for the 1980–81 UEFA Cup, if not already qualified for European competition. Wolverhampton Wanderers won the competition by defeating the reigning holders and European champions Nottingham Forest 1–0 in the final on 15 March 1980. This was their second League Cup success, after winning in 1974.
