2002–03 FIBA Europe Regional Challenge Cup

The 2002–03 FIBA Europe Regional Challenge Cup was the one-season international European competition for men's professional basketball clubs, organised by FIBA. Although it was marketed at the time by FIBA as the 2nd-tier level European club basketball tournament, most would consider it Europe's 4th-tier level competition, after the Euroleague, ULEB Cup and the FIBA Europe Champions Cup. The aim of this tournament was to provide competitive international play for clubs that would otherwise be unable to participate in international basketball. The tournament which featured 4 domestic champions was divided in two conferences: "North" (which consisted of 17 teams) and "South" (which consisted of 11 teams). The season started on 30 October 2002, and ended on 13 February 2003. There were two champions - Azovmash from Ukraine and AEL Limassol from Cyprus. Prior to the commencement of the 2003–04 basketball season, an agreement between FIBA Europe and ULEB basketball was reached regarding the management of Europe's transnational leagues. As a result, the Regional Challenge Cup merged with the Champions Cup to form the FIBA Europe Cup, which was thereafter renamed FIBA EuroCup Challenge.
