The 1989–90 season of the European Cup Winners' Cup was won for the only time by Sampdoria in the final against Anderlecht, 2–0 at Nya Ullevi in Gothenburg, on 9 May 1990. They went on to win 1990–91 Serie A, also being runners-up in the 1991–92 European Cup and in the 1988–89 European Cup Winners' Cup. English clubs were still banned from Europe following the Heysel Stadium disaster, meaning Liverpool missed out on a place, but would have a representative again the following season.

- 1 The first leg of the Partizan—Celtic tie was played at Bijeli Brijeg Stadium in Mostar instead of FK Partizan's home ground in Belgrade due to the club being punished by UEFA as a result of crowd trouble during their 1988–89 UEFA Cup second round first leg match vs AS Roma. Part of the punishment for FK Partizan was playing home matches at least 300 km away from home.
