1955–56 European Cup

The 1955–56 European Cup was the first season of the European Cup, UEFA's premier club football tournament. The tournament was won by Real Madrid, who defeated Reims 4–3 in the final at Parc des Princes, Paris, on 13 June 1956.

The participating clubs in the first season of the European Cup were selected by French football magazine L'Equipe on the basis that they were representative and prestigious clubs in Europe. When the tournament started, Real Madrid, Anderlecht, AC Milan, Rot-Weiss Essen, Reims, Djurgården and AGF Aarhus were the reigning champions of their respective national leagues. English champions Chelsea initially agreed to compete and were drawn against Swedish side Djurgården; however, under pressure from the Football League, who saw the tournament as a distraction to domestic football, they later withdrew from the competition, and were replaced by Gwardia Warsaw of Poland. Scottish champions Aberdeen withdrew under similar circumstances, Hibernian were chosen instead. They were considered one of the best teams in Scotland, having won the Scottish title in 1950–51 and 1951–52, but the main reason they were invited was because they were the only team in the country to install floodlights on their grounds. Dynamo Moscow, the champions of the Soviet Union, did not participate due to climatic restrictions. . This was also the only UEFA tournament to include a representative of Saarland, unified into West Germany in 1957.

The first round pairings were fixed by the organisers and not drawn as would be the case for all future European Cup matches.
