The 1971–72 FIBA European Cup Winners' Cup was the sixth edition of FIBA's 2nd-tier level European-wide professional club basketball competition, contested between national domestic cup champions, running from 4 November 1971, to 21 March 1972. It was contested by 21 teams, five less than in the previous edition, and it marked a reform in the competition's format; a 6-team group stage was introduced, replacing the quarterfinals. Defending champion, Simmenthal Milano, defeated Crvena zvezda in the final, which returned to a single game format, to win its second trophy, becoming the first team to successfully defend its title. It was the third title in a row for an Italian League team. This season's FIBA European Champions Cup final, also featured Italian and Yugoslav League teams, with the same outcome.
