It was held in Italy between 24 and 29 June 1991. Eight national teams entered the event under the auspices of FIBA Europe, the sport's regional governing body. The Palazzo dello Sport in Rome was the hosting venue of the tournament. Yugoslavia won its fifth FIBA European title by defeating hosts Italy with an 88–73 score in the final.
