The English National Cup is an annual basketball knock-out competition held between professional, semi-professional and amateur teams from the various divisions of the National Basketball League. For most of the competition's history, the draw has featured the elite of English basketball, but teams from the British Basketball League currently do not compete in the National Cup, as they compete in their own separate competition, the BBL Cup.
The final is usually played midway through the season, at a neutral venue. The winners of the tournament are awarded the George Williams Trophy, which is named for the man who donated the original cup.
