1999–2000 British Basketball League season

The 1999–2000 BBL season, was known as the Dairylea Dunkers Championship for sponsorship reasons, the regular season commenced on September 15, 1999, and ended on April 8, 2000, with a total of 13 teams competing. For the first time in the league’s history, the 13 teams were split into two geographically divided Conferences, seven in the North and six in the South, with northern teams playing 36 games and southern teams playing 34 games each. The season was dominated by the success of Manchester Giants, conquering the Northern Conference and Championship Play-offs, whilst London Towers were victorious in the Southern Conference and the uni-ball Trophy. Sheffield Sharks were also successful in defending their Sainsbury's Classic Cola National Cup.

London Towers featured in European competition, participating in the Saporta Cup, though with a 3-7 record they finished at the bottom of Group G and thus failed to progress beyond the Group stage. Cross-town rivals Greater London Leopards also made a brief appearance in the Korać Cup but following a 155-189 aggregate defeat to ÍRB Reykjanesbær in the Preliminary round, their first foray into Europe was merely a cameo.

The Southern All-Stars beat their Northern rivals in the eleventh annual All-Star Game with a 177-180 victory, the closest result in the League's history. That was the 7th overall win of the South against the North who won 5 games since the All-Star Game's inception in 1989.
