In the 1971 Intertoto Cup no knock-out rounds were contested, and therefore no winner was declared.
Group stage
Teams from seven countries (West Germany, Sweden, Switzerland, Poland, Czechoslovakia, Austria, and Denmark) participated: four teams from each country. Denmark was the only country that failed to win a group, while West German clubs won two.
