The British Basketball League Cup, often shortened to the BBL Cup, is an annual cup competition for British basketball teams organised by the United Kingdom's top professional league, the British Basketball League. It is one of two peripheral competitions operated by the League during the regular season, with the other being the BBL Trophy. The competition is usually played as a single game knock-out tournament, and is only contested by members of the British Basketball League. The final takes place in early January at the Arena Birmingham in Birmingham.
